Seems like the scans require an account to view. You might want to ask for a "guest" mode. IMO it would really increase Lumafield's exposure since I don't think many people would go through the hassle of making an account.
My father was a surveyor for 40+ years, and he had a Curta he used in the 50s, 60s. and 70s. He put it aside when he started using a calculator in the mid-70s. As a child, I was fascinated by the Curta. It's still in pristine shape, and it's probably the thing he owned that I cherish the most.
I was on the surveying field for much of the 60's until well past the advent of hand-held calculators and remember the Curtas fondly. I wish I had one.
@@Skeeter51244 "I wish I had one." Until Thursday just gone I had never heard of the Curta. On that day I was visiting a customer of my business here in Sydney, Australia, an 85yo retired professor of physiotherapy. She's recently had to move house to an apartment with only one storey, due to mobility issues. The culling of decades of assorted bits and pieces is underway, and she'd offered to give me her Hermes Baby typewriter, which we got to after I sorted out her home IT problems. Before bringing me the typewriter though, she handed me a black metal screw-cap container with only the letters "C-U-R-T-A" printed on it. "You can have this," she offered, "but can you tell me what it is?" Getting the device out of its cylinder was the first hurdle, as it had a left-handed screw thread on it, and Australia is a right-screw nation. When I pointed that out, my client said, "oh, no wonder I couldn't open it." There was a double-sided folded glossy sheet with the device, being a sales brochure that had some scant sample instructions printed thereon. After reading through these and having some hands-on with the device, I pronounced, "it's a calculator." The device is in pristine condition and the lady can't remember purchasing it. In the day or so that I've had the Curta Type 1 I've at least learned how to multiply with it and hope to have more time to become familiar with it soon. I think I've only seen Adam's video about it here because I'd been Googling info about it today. Praise the Algorithm!
There are actually metal build gundams where there are a lot more metal parts for the inner frame. I think I would be really cool if you guys can scan one of those!
Blocks of wood are pretty cool to do. We did one at work a few years back in our CT scanner and you can trace back the growth rings of the tree all through the piece.
There are 200 parts in the Hellboy pistol? That is unreal as is this video. I'm glad you didn't have to disassemble the hammered aluminum ball to see the density inside. Lumafield has really nailed the hardware and the software.
Just wanted to add something to the video (for context I’m an Applications Engineer for a company that has been designing and manufacturing CT systems for years). As was said in the video you do have time vs quality - longer scans are less noisy or you can penetrate more. We can do scans anywhere from a few seconds (you’d be surprised the data you can get from 20 seconds with the right set up) all the way up to hours. And we can scan things from a grain of sand (eg a bronchoscope lens) all the way up to a part that is taller than Adam! We also make different X-ray sources that let us get a resolution of 1um (for lower densities or electronics), but more commonly is a source that can get down to 3um (which is a more general purpose source). The things you scan are pretty much anything and everything- even food items (the porosity and inclusion distribution is important for chocolate!!) I’d be happy to answer any questions (within limits of NDAs), if lumafield and Adam are okay with it, as I don’t want to steal their thunder as the data does look good 😊
Is there a problem if the object that's being scanned has both very dense and very sparse components? Something akin to sensitivity in photography? Edit: and if there is, do you use something akin to HDR to compensate for it? Sorry if I'm a bit hard to understand. English isn't my native language.
What kind of density resolution can you get to? The Gundam's ABS inner frame and styrene armor are only about 0.1gm/cm^3 different in density so that's a lower bound.
@@circleofowls Really? That's incredible. I knew of a couple projects trying to rebuild it or at least create theoretical models for it. But I honestly haven't read about it for probably 10 years.
For anyone in Sydney, the Powerhouse Museum has an exhibition called The Invisible Revealed showing objects scanned with neutron beam and synchrotron X-ray facilities (don't ask me). One of the objects is the Curta calculator. The animated resolution is perfectly defined and mesmerising to watch. I saw it about a month ago and thought "Doesn't Adam Savage have one of these?"
That sounds like a months long project because every "frame" would take a whole day. It would be achievable, but I believe the machine would be more useful on a million other things, this is a matter of will.
If you have the scan with all of the parts in their exact shapes, it should be possible to recreate it as a cad model and do simulations/animations of the thing
Wow... this is one of those videos where I think we are really living in the future. That scan of the Curta is just amazing. There have to be conservators and curators out there who would give their eye-teeth to run some objects through this scanner.
I know a certain Australian Clockmaker and RUclipsr that would love to use the CT-Scanner to make even more precise scans of an ancient artifact he is recreating for a couple of years now. But the mechanism of Antikythera is one of its kind and the musem won't give it away so fast
This was something far beyond what I imagined we'd see! That fidelity is out of a science fiction movie, and the aluminum ball looked like an inverted sun with all the striations and tendrils of density angling towards the center. Phenomenal idea, I wish them well! Also, my suggestion for an object to scan would be something similar to the aluminum ball - something without uniform density or heavy amounts of mechanical parts.
I love this! A couple months ago I was in the makerspace trying to figure out how to convert a 3D model into a handful of slices and one of the people there (Mark) suggested I print it out and he could take it to his work to put in the medical CT scanner. Using a CT scanner to inspect mechanical objects like that is an amazing idea! The models it comes out with are beautiful and now I really want to take up Mark on scanning some stuff and looking at the data it outputs!
In those horizontal cross-sections of the Curta (especially the Curta I at around 12:25 ) there are a lot of lines criss-crossing the image, forming a pattern a bit like a spirograph. Those lines are not actually present in the Curta but are artefacts of the scanning process. Essentially the ring of metal axles are like a cage throwing shadows over the interior. Beautiful, but a bit confusing.
Yup. I found the limitations of Lumafield's technology as interesting as the strengths. It reminds me of peoples' first experiences with 3D printing: there too, when you first hear about it you assume it's just like Star Trek, and it's only as you get some experience that you realize the limitations. A great technology, but not a miracle machine, because you can't beat the laws of physics.
@@agate_jcg While true, those scatter artifacts can be significantly reduced with a good algorithm. It isn't 100% perfect, but it is pretty accurate in some medical/dental CT equipment/drivers these days, and for something with a lot of scatter, it is night and day. For the images of the Curta, it would look near perfect (based on some scans I have done with a computer mouse and a stapler). Hope they have someone on the software side looking into that sort of thing. If you are curious, look up "Metal Artifact Reduction", that seems to be a fairly common terminology.
@@bobsquirrelking Exactly, this kind of work is all based on algorithms, from the initial processing to the noise reduction, etc. Artifacts also don't necessarily detract from its usefulness. e.g. if trying to reproduce something, the artifacts could be cleaned up "by hand" before turning into something printable.
That's phenomenal! But I gotta say, I've been trying for years to get a good price on a Curta computer on eBay, I keep waiting for people to forget about them so the price will hopefully drop, but every year or two some famous tech nerd comes along and tells people about them and the price spikes. So thanks, Adam.
No such thing as a Curta _computer._ They're calculators. Fundamentally different thing. Calling them "computers" is like calling a table saw a "CNC router".
That was wicked! The parts in the Curta computer. The complexity of the Gundam. But the aluminum foil ball! It looked like a scanned moon or small planet. Slicing through is was just so cool!
This was absolutely one of the coolest things I've ever seen. The Al ball blew my mind. You know, it feels kind of like being a god. You can pear inside anything, discover all of it's workings and secrets, then reproduce it if so inclined. Absolutely incredible.
I just sat in front of my computer with my chin on my desk in absolute awe and amazement for the better part of 20min. Thank you for allowing all of us sitting behind our screens to discover this kind of technology. This is absolutely amazing. If this is still in its (somewhat) infancy I cannot wait to see where you guys go in the next 18mos. Keep up the AMAZING work. Sorry, I cannot stop saying that its amazing.
Possibly one of the best episodes for me! Over the years, I've taken so many things apart in order to find out how they work, & utilise or improve a design for something new. Whilst there's nothing technically ground breaking about this, the accessibility, affordability, & visibility is really exciting for smaller scale engineering 👏
What a great tool! Andreas is such a salesman and probably doesn't even realize it. Hope this tech continues to grow, by being able to really dig inside something like the Curta. I think about how NASA could have used something like this in the 60's.
I’ve been amazed by some of Tested’s content, but this left me absolutely speechless. Just imagine what this will allow people to recreate from ancient history
Incredible device. Designers live in a modelling world and tolerances there may or may not match the reality of building a million parts. Manufacturing tool wear; supplier part variations, assembly tolerances all contribute to pretty difficult realities. Where I saw one of these used successfully was a situation where everything was fine with good tolerances in both design and implementation. Then, after 26 month of volume production it started to drift with field failures rising first. Everything returned was parametrically measured and was again within tolerances. So what was it. Well, this technique allowed for the team to see a tolerance "stack up" wherein tolerances - within spec individually - added up to being out of spec but in a small percentage of cases. Some would throw the "corner case" disclaimer card out here but it was root caused to perfectly logical tool wear variances and trying to run tools longer than the data made sense.
Copied from another comment: "We sell the scanners as a service, starting at $3,000 per month for the machine plus all the software, service, and maintenance you need to operate it. Industrial CT service bureaus exist as well, typically charging from $1,000 to several thousand dollars depending on turnaround time and scan requirements."
Oh!! You know what I'd like as a 3d scan... Blade Runner blaster!! I can imagine this service being really useful for antiques and prop collectors, especially when you can't take something apart but you need to see inside from a conservation point. Especially with props.
wow, its a good job i have a capable PC Adam lol When looking at the scans, via your links, i noticed that when rotating or moving the parts around, my GPU was sweating its knackers off lol, as the fans were screaming at me hahaha So im guessing the image is rendered locally on my machine and not over the web, which is great if you have a high powered gaming rig, but maybe not so good if your on a laptop or business PC that is not very highly specced! Ive got to say though i was blown away by the detail and even to my mechanically orientated brain , it was a hell of a lot to take in at once, especially on the Curta's wow so complex and well made!! it's also is mind blowing what being able to essentially copy and past parts means for the future, not only in being able to replace faulty or broken parts for your current items, but to be able to scan print and rebuild old no longer purchasable items, that are no longer being manufactured, or of course parts for them! MIND OFFICIALLY BLOWN!! literally we are coming to a point in mankind's history where anything is possible, its so exciting and leaves me hungry to know what is next!!! :)
this is wild. When adam mentioned museams and histroical restorations/preservations I just thought if I was head of that department i would be on the phone to the these boys yesterday and making an order for one. vey cool video!
One of the greatest strengths seems to be what was briefly mentioned at the beginning of the video, and that was the ability to do scanning for diagnosis or analysis of things like internal o-ring compression. If designers can catch failure points earlier in the process, with less cost, that could begin to improve the reliability of lower end products which normally quickly enter landfills. Extensive testing isn't always cost effective when you're just turning out a low cost item into the market. I could also see some detrimental effects of this, e.g. making it easier for products to be cheaply cloned and dirty the market with knockoffs, but considering how a lot of the current clones happen due to the original source design materials being leaked or sold, they don't need a 3d scan anyway.
Amazing! My grandfather had a Curta - he was an optometrist who used to grind his own lenses, so had need of calculation back in the '60s, and was also something of a hoarder of gadgets and geegaws - and I wish I knew what happened to it. Such a beautiful machine. Seeing inside is amazing. (I also built a Gundam recently - Gunpla abruptly seems to be everywhere! - and it was a very satisfying process. The Bandai engineers have been doing those kits for a long, long time, and it shows.)
Such cool stuff lately Cutting the foil ball in half, getting the Calculator CT scanned, I LOVE seeing inside stuff and how they work more than the thing itself working.
Adam Savage making an entire lifelong career out of nothing more than an unbreakable sense of a child's curiosity is the single most inspiring thing I can think of, right off the top of my head. Do what you love folks.
Spectacular! What an incredible technology, and then to be able to provide links that anyone can manipulate the part to view its insides without needing a whole course to understand how to use the software is amazing.
This is like Star Trek science. The ability to put an object in a machine, create a 3d render of its internal parts, and print every part again, all without opening the object is next level! Also, I'm betting their website just got a ton of hits from Japan and specifically IP addresses owned by Bandai employees.
The really cool part of this way of producing a model. If you ever have an MRI or similar imagining done, ask for the STL file. Can print replicas of your own organs, albeit likely damaged if they are being scanned.
Thats awesome that the guy showing the Gundam CT scan was most excited about that, considering how incredibly impressed and awe struck Adam was when he was building it. As soon as i saw it in this vid I was thinking that it might even be better than the calculator.
I'm betting that in a year or two you'll be able to rent time on these machines. I wouldn't be surprised if a couple of big museums buy them and loan scanning services to smaller museums, too.
That is very cool. Funny thing I noticed is that when they were going through the layers of the aluminum ball, it looked like the animation of the explosion ring that Lucas added to the Death Star explosion in the Episode IV special edition.
I’m a CT Technologist at Seton Medical in Daly City California. This is giving me ideas 😈 J/K Yeah pretty cool stuff man. That Gundam blew my mind. And the fact that it’s web based also blew my mind. Our Siemens Multi Slice, for obvious HIPA reasons, is all done in the computer.
It would be cool if you could also safely do it web based so patients could email Grandma with scans of their medical adventures! I guess you could maybe still email them the file, though.
I’m watching this video and just mind blown this could be a legitimate milestone just thinking about the construction industry and how much it could help and that’s just one trade not talking about everything else hats off to you guys
This is such an awesome video. I had no idea what you did to build that Gundam, that’s fascinating and I am going to watch the video now. Thanks so much for another fascinating video!!!
Adam explores the world around him from whole another view. Thanks Adam. Keep on exploring! Maybe ... Adam Savage can assist the LockPickingLawyer in opening a lock that has not been opened yet from his bucket collection.?
I love seeing industrial CT! Best job ever! I'm a certified NAS-410 Level 2 CT technician performing contract inspection. I scan all sorts of interesting things: aerospace, med device, forensic engineering, reverse engineering, and metrology primarily... My lab uses microfocus sources so we can see resolution down to about 3 microns.
@@jeremiahshoemaker9512 Damn, 3um is amazing. I've gotten ours down to about 15um for really small samples, I'm very jealous. I assume the pig heart was frozen?
@@circleofowls Yeah. It took MANY attempts to get that scan to be successful. The pig heart was actually refrigerated before and after, but not during the scan. It was scanned while suspended in formaldehyde. Fixturing to prevent sample movement was the hardest part of that scan. But yes, when scanning biologic material, it generally has a time limit for scanning...
@@jeremiahshoemaker9512 Lmao, I'll bet. I imagine that was satisfying as hell to get a good image on. It sounds like you have a sensor/source that rotates around the sample?
Hey Adam! You should consider scanning any meteorites laying around the shop. I’m sure you’ve got more than one! Also, how about scanning your omega watch? Or your seiko? Best regards from Mexico
I have a curta that belonged to a great uncle of mine that he got while he was in the navy. My great grandmother held onto it. And my and my ADHD have been obsessed with fidgeting with it every since! Lol It's so freaking fascinating! A can't get enough of a mechanical calculator. It's amazing, and I don't even love math! haha This thing fascinates the hell out of me.
It has been scanned several times. They have pretty good hires 3D scans now. Unfortunately, the pieces are a lot more worn (and a bit smaller!) than they were when it was found. Check the Clickspring channel for more info. He’s an Australian who is building a replica using methods from 2000 years ago… and the videos are gorgeous!
Even after building my own gunpla models I was suprised at seeing the complexity of the inside after the scan, It's so easy to forget just how much detail there is after the casings go on.
Ahh, fond memories of my Curta Type I. Bought it about 15 years ago in an estate sale, they sold out of an old store, I didn't know what it was but it looked very interesting so i paid $1 for it, which was the asking price. Thought at first it was some kind of fishing reel or drilling bits holder. Complete with the receipt, proof of purchase (some banker in Gothenburg / Göteborg Sweden) and the bakelit container. Got it in my hands and realised that it was some kind of a calculator thingomajig, to me unknown what. A few months later I saw a video on RUclips that showed how it worked and so on, wrote a comment describing how I got it and how much I paid, OP contacted my and asked if I was willing to sell it, this being just a week before Christmas and I didn't have much money to buy the kids any real Christmas presents, so I offered it up for sale, the video OP paid me $600 for it and I spent it all on a very good Christmas for both my wife and children. Really wish I had one today, love them.
Speaking as someone who's been trying to find a cheap Curta for literally 20 years, I hate you so much right now. The going price on eBay is around $2000.

Years ago I worked with medical volumetric data. There are more visualization modes which might be of interest: maximum density (along view ray) to spot clumps where they might not belong; minimum density to likewise spot holes. One can use the local density gradient (with fake illumination) to help the human eye extract surfaces from the nebulous volume. If there is enough computational power available, one can shine "god rays" through the volume from one direction and observe scattered light from another direction, to more clearly perceive subtle density variations in areas that ought to be uniform.
I operated an industrial x-ray CT scanner for a couple of years. Right before I left that position I was cleaning out my desk and found a combination padlock that we normally use to lock up misc storage shelves, but we had lost the combo for this one. So I tossed it in the x-ray machine and was able to decode combination from the resulting 3d reconstruction of the internal mechanism. It was one of the more fun scans I ever did!
I personally would love to see a hi res scan of the Antikythera mechanism. I am sure someone else has thought of it, the biggest problem would be safely transporting the fragments to the scanning machine. We have X-rays of it I know, but the ones I've seen don't come close to the same type or level of detail.
I imagine all that copper oxide that has build up on the surface would have a different density than the solid copper parts themselves. With the density filter, it might look really clean.
As seen in the following video, it's looks like CT scans of the mechanism have been done. A comparable program is shown, looking through the mechanism slice by slice and revealing internal gears. However, the software shown in this video appears more powerful and really impressive in how it can isolate parts by density. I imagine researchers are very interested in better scanning technology. That said, it's simple brass gearing in a damaged device and there may not be anything else to discover with the best and latest current scanning technology beyond scans that have been already done. ruclips.net/video/UpLcnAIpVRA/видео.html
This right here is some next generational shit, and they're just casually talking about it as if it were nothing. This thing is absolutely amazing, you guys are amazing
I went and watched the Gundam build to see how it was put together. Finding that a snap-together toy would draw praise for its complexity from the scanners' company rep is a testament to the build quality and love that went into it.
An uncle of mine had a Curta, I used to play with it as a kid, finding it fascinating. Years later he died and I was offered the Curta and I didn't take it thinking it was just a cute mechanical item, but little else. Every day I kick myself for not taking it ...
If you imaged an engine throughout its complete stroke cycle. You could capture the inner workings in action. Possibly most complicated animation of a running engine ever. Forever a fan Adam
What I would like to know is if they can deduce the material from the density; how accurate is the machine in that regard? Could it produce an exploded view of all the parts and their materials? I'm also curious about the resolution; we saw some really tiny screws, but does it resolve the threads of those screws? Could it resolve something as thin as the crushed aluminum sheet matrix in the center of the sphere?
Material detection is included, so long as all your different materials have different densities (actually, it is more complicated than that, but density is the oversimplification they use). If you want to know the chemical makeup, that would require per-pixel x-ray fluorescence spectroscopy, which I highly doubt they could fit in an enclosure that small and would complicate the computation by about an order of magnitude, maybe more. Resolution is largely a function of scanning time and computation time. More images at more angles and more distinct exposure times allows resolution for finer details. I would be very surprised if their best resolution is any worse than 5 micrometers, but that would likely take quite a while longer than their standard stated 40um. And yes, 40um is plenty of resolution for screw threads, in fact the fit of fine screw threads with mechanical components is something that this type of hardware is used to examine in industry. The aluminum ball may present interesting challenges. A dense shell with a far less dense interior requires a lot more fine grained differences in exposure time compared to most subjects which are more dependent on angular differences. It being mostly spherically symmetric exacerbates that.
I have a decade-old GE Phoenix Nanomex at work that will easily get down to 15um, screw threads are trivial to resolve. I'll show you the artifacts left by the machining that made the threads. I'd imagine that better software than what I have could easily export models of various material densities into a CAD program to build an exploded view from.
When he said "we can take it apart without actually taking it apart," and then isolated all the more dense material I was right there with Adam on that gasp
It would be really interesting to see if an AI can understand the relationship between for instance cad files and the products produced using them. Specifically, it would be interesting to see if it can categorize deviation types that can lead to solutions to problems and maybe even automatic adjustments to manufacturing equipment.
Awh man.... I've looking for a Model 1 Curta Calc for quite some years now, and this video will definitely drive prices up (again). I'm still going to enjoy watching the video though! The background story behind these mechanical marvels and it's designer truly is something else.
This is cool. The only downside to the process I would change is the upload of the raw images to the cloud. This creates a risk with proprietary engineering projects getting leaked. I would change it to offer an offline option for rendering of the final images along with the cloud rendering.
Not to mention what happens if the company goes out of business or is sold or the next CEO starts looking for 'reoccurring revenue' opertunities. And of course, what happens if you scan "unapproved objects"?
Oh wow, we live in great times (in most respects). Besides desktop 3D printers, desktop laser cutters etc we now have desktop (sort of) CT scanners? i wouldn't mind playing with that. 6:22 Ah it needs "the cloud" (or in other words, the manufacturer to be in business) for it to work. I don't like that.
My heart sank at the phrase "upload it to the cloud". You're not allowed to actually own anything electronic anymore. You have to give them access to your soul for all eternity. The cloud is Satan incarnate! It is the Beast! It s Skynet!
"the cloud" is just another computer. The scans have to go somewhere for processing. If you bought and owned this machine I'm sure you could have it upload anywhere you want that has the required storage capacity.
@@ehzmia In somecases it is just uploading to access the files etc, but they're suggesting raw data is being sent to be processed there. This would require local software to process, or they build it into the machine itself. Still no excuse to require "the cloud".
Wow. This is extremely cool tech. And the pricing of the product is actually within the realm of reason. It's not quite within the reach of consumer (at $3,000/mo entry level) but even the smallest engineering firms should be able to afford this. What would be even cooler would be able to bring this tech to the consumer. 3D printing has always had the Achilles heel problem of getting a precise copy of a part. If consumers could have affordable metal sintering 3D printers plus a consumer-ready CT scanner MINUS the cloud (there is zero reason for "the cloud" to be part of this equation), the consumer would finally have access to the ability to scan and print metal parts, which is the holy grail of 3D printing. Being able to take, say, a cheap plastic part where some engineer skimped and introduced planned obsolescence and replace it with an identical 3D printed metal part that won't break would be truly game changing. Also great for scanning a device you want to disassemble, repair, and reassemble and make sure you don't miss anything in the process.

My father was a surveyor for 40+ years, and he had a Curta he used in the 50s, 60s. and 70s. He put it aside when he started using a calculator in the mid-70s. As a child, I was fascinated by the Curta. It's still in pristine shape, and it's probably the thing he owned that I cherish the most.
Cool
I was on the surveying field for much of the 60's until well past the advent of hand-held calculators and remember the Curtas fondly. I wish I had one.
@@Skeeter51244 "I wish I had one." Until Thursday just gone I had never heard of the Curta. On that day I was visiting a customer of my business here in Sydney, Australia, an 85yo retired professor of physiotherapy. She's recently had to move house to an apartment with only one storey, due to mobility issues. The culling of decades of assorted bits and pieces is underway, and she'd offered to give me her Hermes Baby typewriter, which we got to after I sorted out her home IT problems.
Before bringing me the typewriter though, she handed me a black metal screw-cap container with only the letters "C-U-R-T-A" printed on it. "You can have this," she offered, "but can you tell me what it is?" Getting the device out of its cylinder was the first hurdle, as it had a left-handed screw thread on it, and Australia is a right-screw nation.

Major kudos to the interface builder over there. I just had a look and it was super easy and intuitive to use.
Those scans are beautiful! The foil ball looks fiery inside too. Amazing.
Thanks!
Check out the latest foil ball vid. Adam got it back from the water jet guys. And did an unboxing video
Just wanted to add something to the video (for context I’m an Applications Engineer for a company that has been designing and manufacturing CT systems for years).
As was said in the video you do have time vs quality - longer scans are less noisy or you can penetrate more.
We can do scans anywhere from a few seconds (you’d be surprised the data you can get from 20 seconds with the right set up) all the way up to hours. And we can scan things from a grain of sand (eg a bronchoscope lens) all the way up to a part that is taller than Adam!
We also make different X-ray sources that let us get a resolution of 1um (for lower densities or electronics), but more commonly is a source that can get down to 3um (which is a more general purpose source).
The things you scan are pretty much anything and everything- even food items (the porosity and inclusion distribution is important for chocolate!!)
I’d be happy to answer any questions (within limits of NDAs), if lumafield and Adam are okay with it, as I don’t want to steal their thunder as the data does look good 😊
Have you scanned anything like ICs, CPUs or GPUs? Can CT scans see inside the silicon? :o
Is there a problem if the object that's being scanned has both very dense and very sparse components? Something akin to sensitivity in photography?
Edit: and if there is, do you use something akin to HDR to compensate for it?
Sorry if I'm a bit hard to understand. English isn't my native language.
What kind of density resolution can you get to? The Gundam's ABS inner frame and styrene armor are only about 0.1gm/cm^3 different in density so that's a lower bound.
is resolution a function of the wavelength of the x-ray?
Can you somehow do film? I'm sure not, but it would be amazing for preservation of badly damaged film, I'm sure.
This thing with the 3d printer feels like a clone machine, you can put in ancient artwork and just print copies, this is so freaking cool
More like a Replicator as seen on the Enterprise D.
How long until someone does a Copy Paste of the Antikythera Mechanism?
@@nasonguy They actually used this exact tech on it, I'd love to see the models published though.
Seems like it could be really great for replicas in museums of you are concerned about damage to an original piece.
@@circleofowls Really? That's incredible. I knew of a couple projects trying to rebuild it or at least create theoretical models for it. But I honestly haven't read about it for probably 10 years.
For anyone in Sydney, the Powerhouse Museum has an exhibition called The Invisible Revealed showing objects scanned with neutron beam and synchrotron X-ray facilities (don't ask me). One of the objects is the Curta calculator. The animated resolution is perfectly defined and mesmerising to watch. I saw it about a month ago and thought "Doesn't Adam Savage have one of these?"
How are there not multi-millions of views to this video? THIS IS AWESOME!
The curta calculator would be lovely to see in "action" by doing a stop motion animation using scans with the CT scanner.
[edit] You might like this excellent 3D animation, it really goes deep into the workings of this thing.
ruclips.net/video/loI1Kwed8Pk/видео.html
That sounds like a months long project because every "frame" would take a whole day. It would be achievable, but I believe the machine would be more useful on a million other things, this is a matter of will.
@@Bobogdan258 you could just animate the 3D model if you understood the movement.
or if they shared the data people could 3d print the parts and make their own
If you have the scan with all of the parts in their exact shapes, it should be possible to recreate it as a cad model and do simulations/animations of the thing
Wow... this is one of those videos where I think we are really living in the future. That scan of the Curta is just amazing. There have to be conservators and curators out there who would give their eye-teeth to run some objects through this scanner.
I know a certain Australian Clockmaker and RUclipsr that would love to use the CT-Scanner to make even more precise scans of an ancient artifact he is recreating for a couple of years now. But the mechanism of Antikythera is one of its kind and the musem won't give it away so fast
@@Craftlngo Yep, Clickspring would benefit from such a scan to check to see what he, and his team, is doing is correct.
@@Craftlngo Were the original scans he's going off of now just 2D?
@@Just_Sara no, the scans are 3D but I could imagine that the scans produced by Lumafield could be an improvement
i don't have use for one but would sacrifice my first born for one of these :O
This was something far beyond what I imagined we'd see! That fidelity is out of a science fiction movie, and the aluminum ball looked like an inverted sun with all the striations and tendrils of density angling towards the center. Phenomenal idea, I wish them well!
Also, my suggestion for an object to scan would be something similar to the aluminum ball - something without uniform density or heavy amounts of mechanical parts.
Thank you! So glad you enjoyed the scans.
A bowling ball?
@@gorillaau I was gonna say exactly that.
i am suddenly reminded of those polished mudballs Adam made. could be interesting.
I love this! A couple months ago I was in the makerspace trying to figure out how to convert a 3D model into a handful of slices and one of the people there (Mark) suggested I print it out and he could take it to his work to put in the medical CT scanner. Using a CT scanner to inspect mechanical objects like that is an amazing idea!
The models it comes out with are beautiful and now I really want to take up Mark on scanning some stuff and looking at the data it outputs!
In those horizontal cross-sections of the Curta (especially the Curta I at around 12:25 ) there are a lot of lines criss-crossing the image, forming a pattern a bit like a spirograph. Those lines are not actually present in the Curta but are artefacts of the scanning process. Essentially the ring of metal axles are like a cage throwing shadows over the interior. Beautiful, but a bit confusing.
Looks like typical photon starvation artifacts there! We see them all the time in patients with metal dental implants.
Yup. I found the limitations of Lumafield's technology as interesting as the strengths. It reminds me of peoples' first experiences with 3D printing: there too, when you first hear about it you assume it's just like Star Trek, and it's only as you get some experience that you realize the limitations.
A great technology, but not a miracle machine, because you can't beat the laws of physics.
@@agate_jcg While true, those scatter artifacts can be significantly reduced with a good algorithm. It isn't 100% perfect, but it is pretty accurate in some medical/dental CT equipment/drivers these days, and for something with a lot of scatter, it is night and day. For the images of the Curta, it would look near perfect (based on some scans I have done with a computer mouse and a stapler).
Hope they have someone on the software side looking into that sort of thing. If you are curious, look up "Metal Artifact Reduction", that seems to be a fairly common terminology.
@@baldilocks2356 you can overcome those radio-opaque material by increaseing x-ray power.
but obviously that's not possible on living humans.
@@bobsquirrelking Exactly, this kind of work is all based on algorithms, from the initial processing to the noise reduction, etc.
Artifacts also don't necessarily detract from its usefulness. e.g. if trying to reproduce something, the artifacts could be cleaned up "by hand" before turning into something printable.
those three objects were perfect demonstrations, absolutely beautiful
Feels great to see Lumafield featured in one of your videos. I did a chunk of mechanical engineering on their prototypes!
That's phenomenal!
But I gotta say, I've been trying for years to get a good price on a Curta computer on eBay, I keep waiting for people to forget about them so the price will hopefully drop, but every year or two some famous tech nerd comes along and tells people about them and the price spikes. So thanks, Adam.
On the upside, maybe someone will copycat them & the price will drop??
Jason, Same here I look about once a month but so far their just to much for my budget. Hoping to find one at a garage sale some day.
there is a type one for sale on there now for $580 and a type two for $710 the rest are selling for around $2000
I got a set of Salt and Pepper grinders I can sell you
No such thing as a Curta _computer._ They're calculators. Fundamentally different thing. Calling them "computers" is like calling a table saw a "CNC router".
That was wicked! The parts in the Curta computer. The complexity of the Gundam. But the aluminum foil ball! It looked like a scanned moon or small planet. Slicing through is was just so cool!
This was absolutely one of the coolest things I've ever seen. The Al ball blew my mind.
You know, it feels kind of like being a god. You can pear inside anything, discover all of it's workings and secrets, then reproduce it if so inclined. Absolutely incredible.
I just sat in front of my computer with my chin on my desk in absolute awe and amazement for the better part of 20min. Thank you for allowing all of us sitting behind our screens to discover this kind of technology. This is absolutely amazing. If this is still in its (somewhat) infancy I cannot wait to see where you guys go in the next 18mos. Keep up the AMAZING work. Sorry, I cannot stop saying that its amazing.
Possibly one of the best episodes for me!
Over the years, I've taken so many things apart in order to find out how they work, & utilise or improve a design for something new. Whilst there's nothing technically ground breaking about this, the accessibility, affordability, & visibility is really exciting for smaller scale engineering 👏
Adam is the best interviewer, real interest and joy and the best questions
Man, this is one of the best corners of RUclips, awesome, deeply thrilling and educational. Just great
What a great tool! Andreas is such a salesman and probably doesn't even realize it. Hope this tech continues to grow, by being able to really dig inside something like the Curta. I think about how NASA could have used something like this in the 60's.
I’ve been amazed by some of Tested’s content, but this left me absolutely speechless. Just imagine what this will allow people to recreate from ancient history
Incredible device. Designers live in a modelling world and tolerances there may or may not match the reality of building a million parts. Manufacturing tool wear; supplier part variations, assembly tolerances all contribute to pretty difficult realities. Where I saw one of these used successfully was a situation where everything was fine with good tolerances in both design and implementation. Then, after 26 month of volume production it started to drift with field failures rising first. Everything returned was parametrically measured and was again within tolerances. So what was it. Well, this technique allowed for the team to see a tolerance "stack up" wherein tolerances - within spec individually - added up to being out of spec but in a small percentage of cases. Some would throw the "corner case" disclaimer card out here but it was root caused to perfectly logical tool wear variances and trying to run tools longer than the data made sense.
Videos like this showcase why we love Adam! I'm curious what a complete scan and image set would cost..?
Copied from another comment:
"We sell the scanners as a service, starting at $3,000 per month for the machine plus all the software, service, and maintenance you need to operate it.
Industrial CT service bureaus exist as well, typically charging from $1,000 to several thousand dollars depending on turnaround time and scan requirements."
Adam Savage is the kind of human every human should try to be in some way. What a man.
Oh!! You know what I'd like as a 3d scan... Blade Runner blaster!!
I can imagine this service being really useful for antiques and prop collectors, especially when you can't take something apart but you need to see inside from a conservation point. Especially with props.
wow, its a good job i have a capable PC Adam lol When looking at the scans, via your links, i noticed that when rotating or moving the parts around, my GPU was sweating its knackers off lol, as the fans were screaming at me hahaha So im guessing the image is rendered locally on my machine and not over the web, which is great if you have a high powered gaming rig, but maybe not so good if your on a laptop or business PC that is not very highly specced! Ive got to say though i was blown away by the detail and even to my mechanically orientated brain , it was a hell of a lot to take in at once, especially on the Curta's wow so complex and well made!!
it's also is mind blowing what being able to essentially copy and past parts means for the future, not only in being able to replace faulty or broken parts for your current items, but to be able to scan print and rebuild old no longer purchasable items, that are no longer being manufactured, or of course parts for them! MIND OFFICIALLY BLOWN!! literally we are coming to a point in mankind's history where anything is possible, its so exciting and leaves me hungry to know what is next!!! :)
I love the journey that’s been taken with the aluminium ball..... what a joy! Thanks for sharing, noodle blown!
It's becoming a running gag like Buster 😆
this is wild. When adam mentioned museams and histroical restorations/preservations I just thought if I was head of that department i would be on the phone to the these boys yesterday and making an order for one. vey cool video!
One of the greatest strengths seems to be what was briefly mentioned at the beginning of the video, and that was the ability to do scanning for diagnosis or analysis of things like internal o-ring compression. If designers can catch failure points earlier in the process, with less cost, that could begin to improve the reliability of lower end products which normally quickly enter landfills. Extensive testing isn't always cost effective when you're just turning out a low cost item into the market.
I could also see some detrimental effects of this, e.g. making it easier for products to be cheaply cloned and dirty the market with knockoffs, but considering how a lot of the current clones happen due to the original source design materials being leaked or sold, they don't need a 3d scan anyway.
Amazing! My grandfather had a Curta - he was an optometrist who used to grind his own lenses, so had need of calculation back in the '60s, and was also something of a hoarder of gadgets and geegaws - and I wish I knew what happened to it. Such a beautiful machine. Seeing inside is amazing.
(I also built a Gundam recently - Gunpla abruptly seems to be everywhere! - and it was a very satisfying process. The Bandai engineers have been doing those kits for a long, long time, and it shows.)
Such cool stuff lately Cutting the foil ball in half, getting the Calculator CT scanned, I LOVE seeing inside stuff and how they work more than the thing itself working.
Adam Savage making an entire lifelong career out of nothing more than an unbreakable sense of a child's curiosity is the single most inspiring thing I can think of, right off the top of my head. Do what you love folks.
Adam is the world's most energetic child. Love these videos.
Spectacular! What an incredible technology, and then to be able to provide links that anyone can manipulate the part to view its insides without needing a whole course to understand how to use the software is amazing.
Thanks! Our software team loved your comment.
This is like Star Trek science. The ability to put an object in a machine, create a 3d render of its internal parts, and print every part again, all without opening the object is next level!
Also, I'm betting their website just got a ton of hits from Japan and specifically IP addresses owned by Bandai employees.
We’re really close to getting replicators.
@@41tinman41 Well, no. Additive manufacturing is good, but it can't do woven fabric,and I doubt it will manage that for a very long time.
And lets not forget the Smithsonian Museums.
The really cool part of this way of producing a model. If you ever have an MRI or similar imagining done, ask for the STL file. Can print replicas of your own organs, albeit likely damaged if they are being scanned.
@@eideticex No. Hospitals won't release the STL files. Privacy reasons. You are able to get some prints, but no actual files.
Thats awesome that the guy showing the Gundam CT scan was most excited about that, considering how incredibly impressed and awe struck Adam was when he was building it. As soon as i saw it in this vid I was thinking that it might even be better than the calculator.
My mind officially blew when he handed Adam the scanned and 3D printed copy. Holy crap, the implications.
As an owner of a Curta the was an amazing thing to see!
As a model maker and 3D printer I am blown away by this. I know it is outside of my finances but OMG the possibilities.
I'm betting that in a year or two you'll be able to rent time on these machines. I wouldn't be surprised if a couple of big museums buy them and loan scanning services to smaller museums, too.
@@darrennew8211 You might check local universities too, I know our local geology dept has one.
That's one of the best things I've ever seen. Adam Savage, a Curta and a CT scanner all in one place? Made my day..
That is very cool. Funny thing I noticed is that when they were going through the layers of the aluminum ball, it looked like the animation of the explosion ring that Lucas added to the Death Star explosion in the Episode IV special edition.
My dad is a retired radiologist. I spent my childhood looking at xrays, ct scans, and mri scans. This is SO COOL
I’m a CT Technologist at Seton Medical in Daly City California. This is giving me ideas 😈 J/K
Yeah pretty cool stuff man. That Gundam blew my mind. And the fact that it’s web based also blew my mind. Our Siemens Multi Slice, for obvious HIPA reasons, is all done in the computer.
It would be cool if you could also safely do it web based so patients could email Grandma with scans of their medical adventures! I guess you could maybe still email them the file, though.
Ha! Yeah, I feel you. I've got a few ideas for our GE Phoenix Nanomex now too.
What an interesting concept! So cool. It was also great to hear Adam's genuine fascination over it all.
I always love when Adam gets really excited about engineering and new innovations.
Adam's enthusiasm is similar to a kid in a toy store. Perhaps just a bigger kid with bigger and more expensive toys. Love his work!
I’m watching this video and just mind blown this could be a legitimate milestone just thinking about the construction industry and how much it could help and that’s just one trade not talking about everything else hats off to you guys
More of this kind of thing please! Cool industry devices are so much more interesting than consumer devices.
This is such an awesome video. I had no idea what you did to build that Gundam, that’s fascinating and I am going to watch the video now.
Thanks so much for another fascinating video!!!
Adam explores the world around him from whole another view. Thanks Adam. Keep on exploring!
Maybe ... Adam Savage can assist the LockPickingLawyer in opening a lock that has not been opened yet from his bucket collection.?
I would like to see the inside of the Loki lock puzzle @lockpickinglawyer just did.
Dude I spent literal hours looking through those scans. Fascinating stuff. Thanks
Thanks! Glad you enjoyed the scans!
This was amazing! Can't wait to see more scans!
I love seeing industrial CT!
Best job ever!
I'm a certified NAS-410 Level 2 CT technician performing contract inspection. I scan all sorts of interesting things: aerospace, med device, forensic engineering, reverse engineering, and metrology primarily...
My lab uses microfocus sources so we can see resolution down to about 3 microns.
What's something really cool you've scanned?
@@Just_Sara Coolest thing I've scanned: actual spaceflight hardware (8 flights and counting...)
Weirdest thing I've scanned: a pig heart in a clinical trial testing a new stent.
Biggest thing I've scanned: heat exchanger cold plate.

@@jeremiahshoemaker9512 Damn, 3um is amazing. I've gotten ours down to about 15um for really small samples, I'm very jealous. I assume the pig heart was frozen?
@@circleofowls Yeah. It took MANY attempts to get that scan to be successful.
The pig heart was actually refrigerated before and after, but not during the scan. It was scanned while suspended in formaldehyde. Fixturing to prevent sample movement was the hardest part of that scan. But yes, when scanning biologic material, it generally has a time limit for scanning...
@@jeremiahshoemaker9512 Lmao, I'll bet. I imagine that was satisfying as hell to get a good image on. It sounds like you have a sensor/source that rotates around the sample?
Hey Adam!
You should consider scanning any meteorites laying around the shop.
I’m sure you’ve got more than one!
Also, how about scanning your omega watch? Or your seiko?
Best regards from Mexico
I have a curta that belonged to a great uncle of mine that he got while he was in the navy. My great grandmother held onto it. And my and my ADHD have been obsessed with fidgeting with it every since! Lol It's so freaking fascinating! A can't get enough of a mechanical calculator. It's amazing, and I don't even love math! haha This thing fascinates the hell out of me.
Super cool! All I could think of was the antikytheran mechanism throughout.
That was my recommendation to scan!
It has been scanned several times. They have pretty good hires 3D scans now. Unfortunately, the pieces are a lot more worn (and a bit smaller!) than they were when it was found. Check the Clickspring channel for more info. He’s an Australian who is building a replica using methods from 2000 years ago… and the videos are gorgeous!
@@peterfireflylund Thanks for the recommendation, as a CT scan tech and Antikythera mechanism geek that channel sounds amazing.
Even after building my own gunpla models I was suprised at seeing the complexity of the inside after the scan, It's so easy to forget just how much detail there is after the casings go on.
Think about the fact that the curta inventor did so in his head.
Or that Ancient Greek mechanical eclipse predictor. Antikythra or something like that.
This technology is amazing, how fantastic a visual they produce! Great stuff Lumafield!
Thank you! Glad you're enjoying the visuals.
Ahh, fond memories of my Curta Type I.
Bought it about 15 years ago in an estate sale, they sold out of an old store, I didn't know what it was but it looked very interesting so i paid $1 for it, which was the asking price.
Thought at first it was some kind of fishing reel or drilling bits holder.
Complete with the receipt, proof of purchase (some banker in Gothenburg / Göteborg Sweden) and the bakelit container.
Got it in my hands and realised that it was some kind of a calculator thingomajig, to me unknown what.
A few months later I saw a video on RUclips that showed how it worked and so on, wrote a comment describing how I got it and how much I paid, OP contacted my and asked if I was willing to sell it, this being just a week before Christmas and I didn't have much money to buy the kids any real Christmas presents, so I offered it up for sale, the video OP paid me $600 for it and I spent it all on a very good Christmas for both my wife and children.
Really wish I had one today, love them.
Speaking as someone who's been trying to find a cheap Curta for literally 20 years, I hate you so much right now. The going price on eBay is around $2000.

Woah this is incredible! I knew these existed, but never seen it in action. Thanks for showing us!
Years ago I worked with medical volumetric data. There are more visualization modes which might be of interest: maximum density (along view ray) to spot clumps where they might not belong; minimum density to likewise spot holes. One can use the local density gradient (with fake illumination) to help the human eye extract surfaces from the nebulous volume. If there is enough computational power available, one can shine "god rays" through the volume from one direction and observe scattered light from another direction, to more clearly perceive subtle density variations in areas that ought to be uniform.
One of the coolest science videos ever!
This reminds me of the first videos about 3d printers. I can imagine these becoming smaller and cheaper and marketed as "3D scanners".
I operated an industrial x-ray CT scanner for a couple of years. Right before I left that position I was cleaning out my desk and found a combination padlock that we normally use to lock up misc storage shelves, but we had lost the combo for this one. So I tossed it in the x-ray machine and was able to decode combination from the resulting 3d reconstruction of the internal mechanism. It was one of the more fun scans I ever did!
"You wouldn't download a car"
Lumafield: "Hold my beer"
I literally gasped when he isolated the Steele parts blew my mind
"There's more engineering in this [Gundam] than in a lot of consumer products."
part of me is jealous of all the amazing stuff Adam gets to see and do, but the other 95% of me is extremely thankful he shares it with all of us .
I personally would love to see a hi res scan of the Antikythera mechanism. I am sure someone else has thought of it, the biggest problem would be safely transporting the fragments to the scanning machine. We have X-rays of it I know, but the ones I've seen don't come close to the same type or level of detail.
I imagine all that copper oxide that has build up on the surface would have a different density than the solid copper parts themselves. With the density filter, it might look really clean.
As seen in the following video, it's looks like CT scans of the mechanism have been done. A comparable program is shown, looking through the mechanism slice by slice and revealing internal gears. However, the software shown in this video appears more powerful and really impressive in how it can isolate parts by density.
I imagine researchers are very interested in better scanning technology. That said, it's simple brass gearing in a damaged device and there may not be anything else to discover with the best and latest current scanning technology beyond scans that have been already done.

Awesome scans. Send your Omega through the scanner!
This right here is some next generational shit, and they're just casually talking about it as if it were nothing. This thing is absolutely amazing, you guys are amazing
"The Next Generation" is probably a better phrase?
I went and watched the Gundam build to see how it was put together. Finding that a snap-together toy would draw praise for its complexity from the scanners' company rep is a testament to the build quality and love that went into it.
An uncle of mine had a Curta, I used to play with it as a kid, finding it fascinating. Years later he died and I was offered the Curta and I didn't take it thinking it was just a cute mechanical item, but little else.
Every day I kick myself for not taking it ...
Ooof, that's gotta hurt.
If you imaged an engine throughout its complete stroke cycle. You could capture the inner workings in action.
Possibly most complicated animation of a running engine ever.
Forever a fan Adam
Love the Curta! I've got one, passed on from my father-in-law.
Adam and this gentleman solved the aluminum ball mystery. Thank you!
What I would like to know is if they can deduce the material from the density; how accurate is the machine in that regard? Could it produce an exploded view of all the parts and their materials? I'm also curious about the resolution; we saw some really tiny screws, but does it resolve the threads of those screws? Could it resolve something as thin as the crushed aluminum sheet matrix in the center of the sphere?
Material detection is included, so long as all your different materials have different densities (actually, it is more complicated than that, but density is the oversimplification they use). If you want to know the chemical makeup, that would require per-pixel x-ray fluorescence spectroscopy, which I highly doubt they could fit in an enclosure that small and would complicate the computation by about an order of magnitude, maybe more.
Resolution is largely a function of scanning time and computation time. More images at more angles and more distinct exposure times allows resolution for finer details. I would be very surprised if their best resolution is any worse than 5 micrometers, but that would likely take quite a while longer than their standard stated 40um. And yes, 40um is plenty of resolution for screw threads, in fact the fit of fine screw threads with mechanical components is something that this type of hardware is used to examine in industry.
The aluminum ball may present interesting challenges. A dense shell with a far less dense interior requires a lot more fine grained differences in exposure time compared to most subjects which are more dependent on angular differences. It being mostly spherically symmetric exacerbates that.
@@hypotheticalaxolotl yes so a bit more than one and a half thousandths of an inch. 40 microns is around 0.0015748031"
@@hypotheticalaxolotl I guess when the Chinese invade we'll forget how to go north then too. So you'd better learn Mandarin.
I have a decade-old GE Phoenix Nanomex at work that will easily get down to 15um, screw threads are trivial to resolve. I'll show you the artifacts left by the machining that made the threads. I'd imagine that better software than what I have could easily export models of various material densities into a CAD program to build an exploded view from.
When he said "we can take it apart without actually taking it apart," and then isolated all the more dense material I was right there with Adam on that gasp
It would be really interesting to see if an AI can understand the relationship between for instance cad files and the products produced using them. Specifically, it would be interesting to see if it can categorize deviation types that can lead to solutions to problems and maybe even automatic adjustments to manufacturing equipment.
Awh man.... I've looking for a Model 1 Curta Calc for quite some years now, and this video will definitely drive prices up (again).
I'm still going to enjoy watching the video though!
The background story behind these mechanical marvels and it's designer truly is something else.
This is cool. The only downside to the process I would change is the upload of the raw images to the cloud. This creates a risk with proprietary engineering projects getting leaked. I would change it to offer an offline option for rendering of the final images along with the cloud rendering.
Not to mention what happens if the company goes out of business or is sold or the next CEO starts looking for 'reoccurring revenue' opertunities. And of course, what happens if you scan "unapproved objects"?
First thing I thought when he said "uploaded to the cloud" is, yearly subscription fee.
@@ElectricGears The cloud is just some else's computer.
I didn't know I needed to see a CT scan of a Gundam. Thank you, Adam. 😁
What about one of the puppets that is in the shop that has a metal armature that can't been seen without destroying a priceless movie relic?
The best 20 minute advert I've seen this year
I inherited one of these from my grandfather, I actually used it to calculate my taxes for several years.
I want one of these just to look at everyday things to see how they are made and assembled. THAT'S SO COOL
Oh wow, we live in great times (in most respects). Besides desktop 3D printers, desktop laser cutters etc we now have desktop (sort of) CT scanners? i wouldn't mind playing with that.
6:22 Ah it needs "the cloud" (or in other words, the manufacturer to be in business) for it to work. I don't like that.
That's super cool, and even cooler that there's links for us to actually view it too.
My heart sank at the phrase "upload it to the cloud".
You're not allowed to actually own anything electronic anymore. You have to give them access to your soul for all eternity.
The cloud is Satan incarnate! It is the Beast! It s Skynet!
"the cloud" is just another computer. The scans have to go somewhere for processing. If you bought and owned this machine I'm sure you could have it upload anywhere you want that has the required storage capacity.
@@ehzmia In somecases it is just uploading to access the files etc, but they're suggesting raw data is being sent to be processed there. This would require local software to process, or they build it into the machine itself. Still no excuse to require "the cloud".
Wow. This is extremely cool tech. And the pricing of the product is actually within the realm of reason. It's not quite within the reach of consumer (at $3,000/mo entry level) but even the smallest engineering firms should be able to afford this. What would be even cooler would be able to bring this tech to the consumer. 3D printing has always had the Achilles heel problem of getting a precise copy of a part. If consumers could have affordable metal sintering 3D printers plus a consumer-ready CT scanner MINUS the cloud (there is zero reason for "the cloud" to be part of this equation), the consumer would finally have access to the ability to scan and print metal parts, which is the holy grail of 3D printing. Being able to take, say, a cheap plastic part where some engineer skimped and introduced planned obsolescence and replace it with an identical 3D printed metal part that won't break would be truly game changing. Also great for scanning a device you want to disassemble, repair, and reassemble and make sure you don't miss anything in the process.
