I'm glad to see the Filament Library using the free access/affiliate link model. I'll be sure to use their links for future purchases, even if I'm buying the same filament I've been buying.
Wow. You can really see the passion of these folks. I love seeing them progressively talking faster during the conversation because they are just so excited to get the information out
They are awesome. I have followed their machines. EDM is such a fascinating tech for home /micro production. That powercore is something i had hoped existed for like 10 years, lol
I had access to a professional EDM machine in my last job - the potential uses are endless: chisels for the lathe made from hardened HSS blanks takes minutes, high precision parts from titanium w/o the work hardening, thin-walled jewelry from super-alloys, a complex clamping mechanism that withstands high temperatures? That EDM machine saved us so much time and money!
Random comment but you should be careful with using superalloys for jewelry; dermatological nickel allergies are a thing and they are not fun. From personal experience even just having Inconel chips on my skin for a couple minutes can cause my skin to get hives.
@@barrag3463You are absolutely correct. Nickel is no joke and we were anal with the alloys we picked for our regular products (professional coffee makers). Some of the stuff we made were display things that only had to survive a photo shooting and were then put in storage. The other thing we found out is that some alloys are pretty "hot" in terms of radiation. Some of our suppliers were pretty careless when smelting scrap metal so we had to check all their shipments with radiation meters...
@@jungletek Note that radiation risk is relative, and depends on the type. If it's alpha, then a simple glaze would work. If it's something else, then dose matters. For example, Uranium glass is safe to keep on a shelf and drink from, but probably not the best for jewelry. Course, that doesn't fly for a commercial product without regulatory approval.
@@jungletek China. From what I hear, a lot of the imported leather goods are so radioactive that they get confiscated by customs... there was a wave of cases of radiation sickness in major cities across China last year that can be linked to the burning of contaminated coal from a mine in Northern China. What virtually nobody in the West is aware of, is the fact, that for every kilogram of neodymium (essential for EVs and wind turbines), the same amount of radioactive Uranium and Thorium is dumped in open tailings ponds and then carried as dust across Northern China and India. Cancer rates of 44% are "normal" in the regions where mining/refining of those rare earth elements is taking place...
You can't deny the passion of the guys at Rack Robotics to make all this. I really hope they can create a successful company. I ordered the fish tank already
i would make this shredder a stand alone motor powered addon you can bolt to the back of a bambu lab printer, to take care of the filament poop it ejects. i was already planning on building my own micro shredder just for this.
I can't even express how much respect I have for the guys that made that EDM machine. If I'll ever need to machine gears, this would be the way... I'm not sure I _need_ this machine, but I want it.
With professional wire machines, the use cases tend to be: Since there is no tool to part contact, they are incredibly accurate. If something needs to be spot on, wire it. 2. It cuts anything conductive, without care for how hard it is. It will cut hardened steel. 3. It can cut an almost square inside corner (limited by the wire diameter which is very small). These 3 combine to make wire machines the primary method for making stamping tools
@@judlex7300 That would be sick at one point but there are other options. On corner wire edm stops for short period of time to machine corner. Or you can use smaller diameter of wire to make even smaller radius. For that kind od WEDM we use 0.1mm wire instead of standard 0.25 or 0.3mm 😎
@@judlex7300 almost, but no. You need a bit of space between the wire and the metal you are cutting, for where the spark jumps and where the water washes out the burned metal. It's about half the wire diameter. So with a square wire you'd get a radius of about half the wire diameter rather than the whole diameter. Also, I suspect it won't be an arc, but rather some kind of parabolic who knows what shape. A lot of machines are made to run multiple wire diameters. 0.010 for most cuts, plus .002 for the super fine stuff. But really, .01 inside radius is pretty damn small, and you can usually just deal with that.
These two guys at Rack Robotics EDM know their stuff, inside and out! Very impressive! Looks like a mostly "turn key" unit for practical use will end up ~ $2000 to $4000, which is and absolute bargain! Good luck to them and thanks for the work to get it to "here".
That's the kind of thing every machine shop is going to want right next to their 3D printer. Massive market for "it just works" while open sourcing everything.
as an american who lives very far from colorado i hope you had a good time and i hope our people were hospitable. Im a huge fan and i appreciate your work. these interviews were very interesting. these people are very passionate about their work and i love seeing all these people in one place with unique ideas all united towards the same goal
@26:50 I have a bunch of hobbies, including the fiber arts, and this happens all the time with yarn, too. You always have to look at the dye lots on the yarn labels, to see which were dyed together, and therefore have the same color. If you get yarn that looks identical, but has different dye lots, and then knit with one for half a sweater, and with another for the other half, you'll most likely see it. It'll look like half the sweater was left out in the sun for years and faded a bit. You can get around it pretty well by alternating skeins every row. That's a bit harder with 3D printers.
Filament library could be really useful once they fill out the selection. Of my 15 rolls of filament I own, a good 7 are missing from the list, including a few Bambu colours. It would be great if all the filament manufacturers got behind this and sent him the tiny lengths he needs.
The wire EDM machine would be a godsend for me in NDT. I do ultrasound flaw detection in industry and being able to machine a "test block" that would have miniscule flaws to practice before a full run would be great.
The ability to make High Quality Injection Molds for things like the Precious Plastic type “Makerspace Scale” Injection Molding Machines would be a HUGE improvement this Open Source EDM Development is Enabling. I don’t know enough about injection mold design, and force needed etc, but if they can get molds that can reliably churn out actually useful/valuable things like LEGOs, or Buckets etc that would be huge.
@@Hukkinen Yep, the mold development (several prototypes and a final one that lasts for enough production runs) is generally the expensive part of injection molding. Needs to be highly accurate, but also very strong, and often with mechanical designs to be able to get the resulting product out. Once you have a good mold, every individual production run is cheap.
This is enormous news, I've been waiting for this technology ever since Ben Krasnow demonstrated a sort-of-affordable EDM plunge drill device some years back! I have a hypothetical project that would require high precision machining on very tough steel (e.g. hardened 4340), it would be tremendously useful to have the cut made on a hardened piece to avoid distortions from the heat treatment process. I am very excited with the prospects DIY EDM will provide.
already had the link for the filament colors library saved, wonderful idea. The EDM equipmentlooks really interesting. Also, yes, I love the idea of the mini shredder. I've got a few "medium" size moving boxes full of waste PLA just waitingto be shredded and re-used. that'd be a start, at least.
On the filament colour library... I will definitely be using this! I've bought some truly disappointing filaments in the past, from a "gold" that was more brown to "orange" that was "emoji yellow" (fortunately I had good uses for that one).
The EDM machine is so cool. Looking forward to finding an opportunity to picking up one of those machines. And the color matching library - that's a resource that I hope never goes away.
I used to operate EDM machines at one of my previous jobs and it is STILL one of my absolute favorite forms of metal machining. I was making jet turbine components and the tolerances we worked with were the tightest in the plant. Incredibly fun and ridiculously interesting!
Very cool exhibits you showed here. The cutting tech that can be available for the enthusiast is great. The filament indexing and color matching website is superb and will definitely be using that. Thanks for sharing your experience
for my study we went to a couple of part manufacturers that also used Wire EDM and i have to say, what these two guys did is raelly impressive, even if it's only a part of the quality of industry standard machines. this is the kind of machine that would fit nicely next to your desktop 3D printer standing in the workshop
Thanks you @CNCkitchen for constantly sharing such inspiring topics. EDM is an amazing example of technology that could be readily available to hobbyists, and professionals. EDM combined with 3d-metal printing offers so many amazing possibilities. Truly stuff of sci-fi becoming reality.
As a retired U.K. Boilermaker, now hobby maker, I would love to hit Open Sauce. I just cannot justify the cost of flying over the pond & the $200 admission. Love the E.D.M. Great coverage, just the right amount of detail.
Props to the EDM guys. It's a very interesting and useful technology and making it available for cheap (compared to regular EDM) will make a huge difference. Looking forward to how this will change prototyping and small scale manufacturing for small businesses and hobbyists.
We just bought one of the v2 for the ender 3. Looking forward to testing and tinkering with it. These guys are very cool. Happy to put money down on their project.
Your channel makes me feel so excited for tech that others may be cynical about and i apreciate it. U make me feel better about all the stuff i bought lol
we send out a lot of work to our parent company for their edms, definitely a super useful manufacturing technique. I small form shredder for plastics and stuff would be super useful for me. This one is a bit small but I like the idea. Sometimes I have to get rid of things that aren't recyclable and I can't find a new home or use for and have to just toss it. Shredding it could reduce the space the waste takes up or possibly give me an avenue to mess with dome diy extruding or something.
Super cool! Open source machining, CNC, printing is moving at speed. Can't wait to see small components like what you'd see in a mechanical watch made with Open Source EDM.
I'mma definitely send some filament to that project, and give them some donation as well. That's an awesome project that'll help a ton when it comes to finding replacement colors, or colors that might look good together.
I thought about going to. RMRRF. Wish I had cause I probably would've met that stand and have been able to donate in person. Though.. I actually picked up like 15 spools of filament that Saturday from someone who was leaving the hobby. So, I guess I may have lost out on that deal if I did go. (100 bucks for I believe 14 spools of PLA, and 2 spools of TPU. Don't remember exactly. Most were 800+ grams left. Only two had less)
I love the innovation. For me I've been looking for a small scale shreadder for ages. Most current ideas are too expensive and bulky. I'd love to give that diy one a try.
My dad was head of matrix maker shopn and there was such a big machine the wire was copper tools and the medium was a sort of oil. It was end of '70. I loved that machine its was magic at the time for me.
Absolutely yes. An affordable shredder/extruder combo to turn my failed prints and purges and brims and support into usable filament again? Even if I have to get some virgin plastic pellets, it would be SO worth it. Same thing goes for water/soda bottles. I would much rather use them for filament than sending them to the recycling center. Especially because I'll know they're actually being recycled. A lot of post-consumer plastics don't actually get recycled for various reasons.
There are machine shops that use EDM to drill down into hardened steel like broken taps or other hardware if you are unable to remove them with heat or easy outs. Amazing tech.
A cheap shredder and extruder combination would be amazing. The resulting filament may not be the best but would be ideal for test prints and prototyping and reduce waste.
I love this story and the developments these guys are making in the process. These machines will change the world for makers.Thanks for your hard work guys. I look forward to seeing Production. I will definitely buy one, once the kinks have been worked out.
Also, I'm really excited to see any advancement in home plastic recycling, and shredding seems to be 'the weakest link' right now. I kind of stopped 3D printing items 'recreationally/experimentally' when my boxes for storing sorted waste material filled up. It feels too bad to just throw plastic out like that when it's only been used once and I know the exact material, so I've been kind of... holding out for a way to affordably recycle it, and only printing things with immediate practical uses in the meantime. If you have a 3D printer with constant, closed-loop filament diameter sensing (shouldn't be too hard? Technically you want the cross-sectional area [or in-nozzle pressure?], not just the diameter, since it could be out-of-round, is this really that bad?), you could use fairly inaccurate home-extruded filament effectively, as long as the equipment to shred and extrude it is accessible.
I'm loving the color library! I love that guy and his use of nerd power to accurately code the colors... reminds me of when was that the early 2000's when you could bring anything into a paint store and they could scan it! WE NEEDED THIS!!! Thank you! Also thanks T for bringing this to our attention. It has been my dream, I only have about 50 examples & I'm not even sure how I afforded that... really, thank you! 1 critiscm/ask about the site if the gentleman sees this, could you maybe add a country availability filter? That "North" filament is nice and plentiful, but not in the US😢
Industrial EDM machines have apps for your phone to monitor weekend long burns. Most mold shops have at least a sinker and a wire EDM. I'm a laboratory machinist at a university in the states so I get to cut lots of weird materials. I've would love to cut a diamond!! My least favorite material to EDM is some weird steel (can't remember the name) made for heating elements. Kept breaking the wire no matter what setting I changed!! Grr!! WC cuts like butter!
...open-source CNC wire EDM could provide a novel path to the last few precision metal parts required for the old dream of a (room full of) Reprap(s) that make all their nontrivial parts. At that point you need... some way to source or produce ceramic tubes/guides (for the EDM machine, for hotends, etc.), and commodity hardware and semiconductors. I love seeing the capabilities of open-source benchtop manufacturing expand!
That Opensource EDM-Machine is awesome. I thought about getting the one Applied Science used, but the EDM-driver alone costs 5k. So those guys are the way to go for hobbyist.
The problem with EDM is the consumable cost. Wire cut around 100$ to cut 10 feet of 10mm Aluminium (or 100$ to cut 3 feet of steel). High precision is not cheaper than ever, but still has a steep price.
I LOL'd at that too but that's where electric code has the break. It used to be 70V but they dropped it. (Can't remember what to.) I worked with 70/100V PA systems and laughed when they changed the rule. I've never heard of anyone getting hurt by a PA system.
@@button-puncher LOL, in my country low voltage is bellow 1000VAC/1500VDC. We do have a lower class which would literally translate to "small voltage" and that's bellow 50VAC/120VDC.
Uh, nice. I have seen my first wire EDM system at CERN. It was about one cubic meter in size, working on a huge metal part. Really impressive. Very nice to see the desktop machine!
The EDM is so cool! I used a Charmilles wire EDM for production of intricate othepaedic implants from Titanium sheet. Make a stack an inch high. Drill a start hole and next day stacks of completed cut parts. A mini shop version would be awesome! Nice work guys! Hes right about production EDM machine being expensive the Charmilles machine was about $400k in 1980s. 😮
The Bettawire looks absolutely amazing. I was wondering when someone would build something like this. I'll wait another year or two to let them iron out the kinks, but I'm pretty sure that I will buy one of those sooner or later.
The best tool/machine isn't the one that's the best, it's the one you can have/afford/manage. I develop software for industrial extruders: to give you an idea, during processing they use tens of kg of plastic per minute, the feed screw alone weighs 20 tons and they have tanks of 1 or 2 tons of pellets. They are certainly better and faster than our 3D printers: but if you don't have several millions, a warehouse, 4 or 5 operators etc. you can't have or use it. Same thing for CNC: I modified an Ender 5 Pro and a Plus to also use a spindle. In aluminum I can only do 0.16/0.2 DOC: slow but better than nothing. Next thing: EDM for sure.
the shredder is by far the most interesting, ontop of a cheap shredder we need a cheap filament creator (cheaper than the one you tested already) and cheap filament dryer
Yah I can see an EDM machine in my future. Disappointing that I live 10 minutes from the event location but didn’t know about it until I saw your video.
Those Robo Rack guys have done some impressive stuff. EDM isn't something that I've considered. I remember seeing an article in Popular Mechanics as a child about making a simple home EDM for busting out broken taps. It's really cool to see such a thing refined and polished so many years later to the point that it's a fully automated process.
Honestly, I got into 3D printing with the intent to try modeling and creating custom tools for modular multi-tools like the GOAT tool and Roxon Flex. Wire EDM looks like an amazing way to create sturdy tools for those systems. I'm probably years away from making a purchase like that, but it fits my ideas perfectly.
Saw their (Morlock's) Betta Wire video a few days ago - really excited for it, though I'll wait a while before purchasing one. I have no right to request this, but it'd be nice if you could link to their video in the description for those curious - I think it'd be enjoyed by this crowd.
25:00 the leds will vary output with age. Color balance can help but not compensate. You need to tune led intensity/color on a golden sample and calibrate the led.
A simple EDM machine would be a huge time saver for a machine shops in a bind. You break a tap in a hole you are hosed unless you can get an edm machine to burn out the tap.
The filament color match is pretty cool resource. As a future enhancement they might get full spectra under controller light, not just RGB from a camera. That will help with color rendering index issues from LEDs or any other source they use, or one uses, to get the most consistent results. Also for those filaments that fluorescence, maybe also have a controlled light source to trigger that, ie UV in different parts of spectrum. Very neat idea.
Hi! They use a spectrophotometer for the color measurements, and are working on getting an improved one in the future. The photograph is used for comparative color.
About a month ago I bought 6 different spools of "bright green" PETG trying to get the right color. Well, crap. At least I won't have to deal with that again in the future. Thanks for the info!
Yessss....need shredding figured out ....we have tried blenders and coffee grinders, even a cross cutting office paper shredder. And the everpresent concern is increasing surface area and introducing humidity. Genuinely want to be more responsible and recycle more material so this is a desperate need. Extruding isnt actually that bad .....still a bit pricey .... but far easier than shredding
can't wait for edm to become the next affordable hobbyist machining technique, I can feel it being around the corner!
I already listen to edm all the time ¯\_(ツ)_/¯

EDM is an amazing example of technology that could be readily available to hobbyists, and professionals. EDM combined with 3d-metal printing offers so many amazing possibilities.
Truly stuff of sci-fi becoming reality.
As a retired U.K. Boilermaker, now hobby maker, I would love to hit Open Sauce. I just cannot justify the cost of flying over the pond & the $200 admission. Love the E.D.M. Great coverage, just the right amount of detail.
Props to the EDM guys. It's a very interesting and useful technology and making it available for cheap (compared to regular EDM) will make a huge difference. Looking forward to how this will change prototyping and small scale manufacturing for small businesses and hobbyists.
Man this guy is one of the absolute coolest nerds on this planet. I love data, so his videos are just the best thing ever. So much chart p0rn
We just bought one of the v2 for the ender 3. Looking forward to testing and tinkering with it. These guys are very cool. Happy to put money down on their project.
Your channel makes me feel so excited for tech that others may be cynical about and i apreciate it. U make me feel better about all the stuff i bought lol
we send out a lot of work to our parent company for their edms, definitely a super useful manufacturing technique. I small form shredder for plastics and stuff would be super useful for me. This one is a bit small but I like the idea. Sometimes I have to get rid of things that aren't recyclable and I can't find a new home or use for and have to just toss it. Shredding it could reduce the space the waste takes up or possibly give me an avenue to mess with dome diy extruding or something.
Super cool! Open source machining, CNC, printing is moving at speed. Can't wait to see small components like what you'd see in a mechanical watch made with Open Source EDM.
I'mma definitely send some filament to that project, and give them some donation as well.
That's an awesome project that'll help a ton when it comes to finding replacement colors, or colors that might look good together.
I thought about going to. RMRRF. Wish I had cause I probably would've met that stand and have been able to donate in person.
Though.. I actually picked up like 15 spools of filament that Saturday from someone who was leaving the hobby. So, I guess I may have lost out on that deal if I did go. (100 bucks for I believe 14 spools of PLA, and 2 spools of TPU. Don't remember exactly. Most were 800+ grams left. Only two had less)
One cool note around chemical machining that they were talking about at the start is that it's the method used to rifle the barrels of FGC9s!
I love the innovation.
For me I've been looking for a small scale shreadder for ages. Most current ideas are too expensive and bulky.
I'd love to give that diy one a try.
I used to setup and operate a few older Sodick EDMs and one new AgieCharmilles at a tool and die shop. Super interesting and fun process.
My dad was head of matrix maker shopn and there was such a big machine the wire was copper tools and the medium was a sort of oil. It was end of '70. I loved that machine its was magic at the time for me.
Definitely down for a shredder! Especially if it can handle HDPE #2 plastic. I have a huge collection of colors.
Man the EDM is mind blowing, Epic job guys keep it up looking forward to buy one soon.
Absolutely yes. An affordable shredder/extruder combo to turn my failed prints and purges and brims and support into usable filament again? Even if I have to get some virgin plastic pellets, it would be SO worth it.
Same thing goes for water/soda bottles. I would much rather use them for filament than sending them to the recycling center. Especially because I'll know they're actually being recycled. A lot of post-consumer plastics don't actually get recycled for various reasons.
There are machine shops that use EDM to drill down into hardened steel like broken taps or other hardware if you are unable to remove them with heat or easy outs. Amazing tech.
A cheap shredder and extruder combination would be amazing. The resulting filament may not be the best but would be ideal for test prints and prototyping and reduce waste.
we utilize sinker EDMs commercially for med device manufacturing. super cool to see the tech making its way to the hobbyist scene!
I love the Wago bus on the tool head! I use all different kinds of Wagos for low voltage AV/datacom projects at work :)
I love this story and the developments these guys are making in the process. These machines will change the world for makers.Thanks for your hard work guys. I look forward to seeing Production. I will definitely buy one, once the kinks have been worked out.
The Shredder is really eye catching! I want to build one and get a filament extruder now.
Amazing machines, and amazing lavalier microphones, Stefan! Audio quality on this video in a difficult environment was fantastic!
Also, I'm really excited to see any advancement in home plastic recycling, and shredding seems to be 'the weakest link' right now.
I kind of stopped 3D printing items 'recreationally/experimentally' when my boxes for storing sorted waste material filled up. It feels too bad to just throw plastic out like that when it's only been used once and I know the exact material, so I've been kind of... holding out for a way to affordably recycle it, and only printing things with immediate practical uses in the meantime.
If you have a 3D printer with constant, closed-loop filament diameter sensing (shouldn't be too hard? Technically you want the cross-sectional area [or in-nozzle pressure?], not just the diameter, since it could be out-of-round, is this really that bad?), you could use fairly inaccurate home-extruded filament effectively, as long as the equipment to shred and extrude it is accessible.
I'm loving the color library! I love that guy and his use of nerd power to accurately code the colors... reminds me of when was that the early 2000's when you could bring anything into a paint store and they could scan it! WE NEEDED THIS!!! Thank you! Also thanks T for bringing this to our attention. It has been my dream, I only have about 50 examples & I'm not even sure how I afforded that... really, thank you! 1 critiscm/ask about the site if the gentleman sees this, could you maybe add a country availability filter? That "North" filament is nice and plentiful, but not in the US😢
Industrial EDM machines have apps for your phone to monitor weekend long burns. Most mold shops have at least a sinker and a wire EDM. I'm a laboratory machinist at a university in the states so I get to cut lots of weird materials. I've would love to cut a diamond!! My least favorite material to EDM is some weird steel (can't remember the name) made for heating elements. Kept breaking the wire no matter what setting I changed!! Grr!! WC cuts like butter!
...open-source CNC wire EDM could provide a novel path to the last few precision metal parts required for the old dream of a (room full of) Reprap(s) that make all their nontrivial parts. At that point you need... some way to source or produce ceramic tubes/guides (for the EDM machine, for hotends, etc.), and commodity hardware and semiconductors. I love seeing the capabilities of open-source benchtop manufacturing expand!
That Opensource EDM-Machine is awesome. I thought about getting the one Applied Science used, but the EDM-driver alone costs 5k. So those guys are the way to go for hobbyist.
Rack Robotics are amazing for making this open source, I cant wait to build one they have so many uses!
I would definitely like to see you continue with home recycling. My sons' school has a maker space and design class and failed prints abound. So cool!
The problem with EDM is the consumable cost.
Wire cut around 100$ to cut 10 feet of 10mm Aluminium (or 100$ to cut 3 feet of steel).
High precision is not cheaper than ever, but still has a steep price.
"high voltage"
"65 volts"
oh, that's adorable :3
I LOL'd at that too but that's where electric code has the break. It used to be 70V but they dropped it. (Can't remember what to.)
I worked with 70/100V PA systems and laughed when they changed the rule. I've never heard of anyone getting hurt by a PA system.
@@button-puncher Where we are, the limit for "high voltage" is 48V. We are legally required to let people know this.
@@button-puncher LOL, in my country low voltage is bellow 1000VAC/1500VDC. We do have a lower class which would literally translate to "small voltage" and that's bellow 50VAC/120VDC.
In some companies like the one i work, we consider high voltage from 50v cause the amperage is the one killing you.
I was expecting
20kV for spark eroding, but 65V it is 😂😂 !
Uh, nice. I have seen my first wire EDM system at CERN. It was about one cubic meter in size, working on a huge metal part. Really impressive. Very nice to see the desktop machine!
The EDM is so cool! I used a Charmilles wire EDM for production of intricate othepaedic implants from Titanium sheet. Make a stack an inch high. Drill a start hole and next day stacks of completed cut parts. A mini shop version would be awesome! Nice work guys! Hes right about production EDM machine being expensive the Charmilles machine was about $400k in 1980s. 😮
The Bettawire looks absolutely amazing. I was wondering when someone would build something like this. I'll wait another year or two to let them iron out the kinks, but I'm pretty sure that I will buy one of those sooner or later.
That first EDM guy was talking to people who know nothing and introducing people to it the second guy was KNOWLEDGE
The best tool/machine isn't the one that's the best, it's the one you can have/afford/manage.
I develop software for industrial extruders: to give you an idea, during processing they use tens of kg of plastic per minute, the feed screw alone weighs 20 tons and they have tanks of 1 or 2 tons of pellets. They are certainly better and faster than our 3D printers: but if you don't have several millions, a warehouse, 4 or 5 operators etc. you can't have or use it.
Same thing for CNC: I modified an Ender 5 Pro and a Plus to also use a spindle. In aluminum I can only do 0.16/0.2 DOC: slow but better than nothing.
Next thing: EDM for sure.
Heck yeah! EDM for all! That is extremely exciting to me!
Great coverage/showcasing of these interesting projects!
the shredder is by far the most interesting, ontop of a cheap shredder we need a cheap filament creator (cheaper than the one you tested already) and cheap filament dryer
Amazing what was created in the face of adversity (job loss). Brilliant ideas!
Yah I can see an EDM machine in my future. Disappointing that I live 10 minutes from the event location but didn’t know about it until I saw your video.
Those Robo Rack guys have done some impressive stuff. EDM isn't something that I've considered. I remember seeing an article in Popular Mechanics as a child about making a simple home EDM for busting out broken taps.
It's really cool to see such a thing refined and polished so many years later to the point that it's a fully automated process.
Honestly, I got into 3D printing with the intent to try modeling and creating custom tools for modular multi-tools like the GOAT tool and Roxon Flex. Wire EDM looks like an amazing way to create sturdy tools for those systems. I'm probably years away from making a purchase like that, but it fits my ideas perfectly.
Saw their (Morlock's) Betta Wire video a few days ago - really excited for it, though I'll wait a while before purchasing one.
I have no right to request this, but it'd be nice if you could link to their video in the description for those curious - I think it'd be enjoyed by this crowd.
25:00 the leds will vary output with age. Color balance can help but not compensate.
You need to tune led intensity/color on a golden sample and calibrate the led.
Unglaublich was die Leute alles machen - echt geil !!
First time I've bought anything from an ad. Saw you guys had TS101 compatible heat set tools kits and snapped it up straight away.
A simple EDM machine would be a huge time saver for a machine shops in a bind. You break a tap in a hole you are hosed unless you can get an edm machine to burn out the tap.
The filament color match is pretty cool resource. As a future enhancement they might get full spectra under controller light, not just RGB from a camera. That will help with color rendering index issues from LEDs or any other source they use, or one uses, to get the most consistent results.
Also for those filaments that fluorescence, maybe also have a controlled light source to trigger that, ie UV in different parts of spectrum.
Very neat idea.
Hi! They use a spectrophotometer for the color measurements, and are working on getting an improved one in the future. The photograph is used for comparative color.
About a month ago I bought 6 different spools of "bright green" PETG trying to get the right color. Well, crap. At least I won't have to deal with that again in the future. Thanks for the info!
With the sparkly surface, small batch ornamental item manufacturing from upcycled metals is what I might use it for.
Yessss....need shredding figured out ....we have tried blenders and coffee grinders, even a cross cutting office paper shredder. And the everpresent concern is increasing surface area and introducing humidity. Genuinely want to be more responsible and recycle more material so this is a desperate need. Extruding isnt actually that bad .....still a bit pricey .... but far easier than shredding
