@@Ismsanmar actually I think Strange Parts’ second channel (Stranger Parts) had the best video on this machine, as far as actual product reviews go, of the 4-5 I ended up watching lol. I think this video is as much about the actual project as it is about the machine used to make it.
@@clonkex The traces at the very least have to run along the inside of some topological hole (e,g, tube) in the printed shape which is connected to the volume of plating fluid. Can't expect to make traces anywhere the fluid can't reach.
I used to run a Shipley 3000 PTH line, and we were adding a 500-1000ml of formaldehyde to the electroless (150 litre) bath every 3-4 hours to keep the plating thickness uniform throughout a production day.
I was working on 3D printed electronics in my phd. At the begining I had similar idea that you presented in 16:20, but my problem was achieving copper in the whole sintered layer. Finally I ended up with FDM and precision dispensing with laser curing of MOD ink, which composition I developed myself.
I'm just interested in science in general and find this man to be an utter hero despite the world of intellectual gatekeeping around. A genius that needs to be recognized. Thanks for amazing videos over the years!
YT is weirdly interesting place. Not sure how did I ended up here, because this is not really field of my interests, but I found it fascinating. Not just the scientific part of it, but also the passion and creativity. People really have extremely wide range of hobbies. :)
Dude, if you could patent that idea of using a dichroic mirror to activate the catalyst as it prints, I bet you'd make a small fortune! You'd be a thousandaire in no time!
As usual, what Ben manages to achieve is amazing. These Micronics SLS printers look like they'll turn into a very good product, but I'd have been impressed if the video was just that he'd worked out DIY electroless copper plating, as someone who has wished he could do it before now. A more detailed video showing exactly how to do DIY electroless copper plating would be very nice! The fact that before anyone even has a Micronics SLS printer via the Kickstarter, Ben has already worked out how to hack one to make it print 3d circuit boards within prints is awesome.
This is the most criminally underrated channel on RUclips, dare I say. The amount of knowledge, skill, and time that goes into this should demand millions more views. Perhaps if you expanded to partnering with someone to handle a mixture of marketing as well as someone who can incorporate some video illustration and distill some of this into bite-sized pieces of knowledge for the laypersons? Anyways, hope you're doing well!
This is awesome, I can see laptops where the case is the motherboard, leaving more room for battery and cooling and much thinner devices and so much more.
It's incredible how patents hinder progress across all areas. In the case of 3D printers, the delay was also because there were closed patents that were renewed for decades, until the companies eventually gave up as they couldn't find a viable business model. Once those patents were released, homemade 3D printers began to emerge worldwide. I didn't know that even chemical formulas were patented ... basically, we're in a dark age where large monopolies have appropriated all knowledge and technological development. I had proposed developing a system of Cooperative Patents, along the lines of GPL licenses and open-source software, at a university in Argentina. But I didn't receive any support. On the internet, I saw that there's another person (Frederik Questioner) who tried to propose something similar with the Open Patent Office, but it didn't gain much traction either. Excellent video sharing your insights.
@@KallePihlajasaari What do you mean by 'support the initiative'? And what things couldn't you find on Google? Was it about Frederik Questioner or about my proposal?
@@jonidimo I am in favour of placing as many 'patents' as possible into the public domain. Specifically I would like to see unused patents be easier to licence or forced into the public domain. I would also like patents from companies that become insolvent or close down move into the public domain. Having a national patent pool that provides free or very cheap access to patents from any academic work or the above groups would increase the chance of small startups getting started and the more small business we have the less globalist monopolies we have. One provides resilience the other slavery. I think I went looking for Frederic because you mentioned him. However you are just a random userid so there is no way to find what you have been working on so no point in spending too much time guessing.
I've tried to find a working electroless copper plating solution recipe before without like. Tried this today and I accidentally copper costed my thermocouple! I'm excited to have a working solution
This is a crazy cool technique that basically lets you do dual density parts and create electrical paths between them for creating wearables it basically means that you have a 3D printer but double and I think that's going to create some really interesting part
I think that we all hate the circuit boards that are covered in epoxy or something similar and then it is impossible to see what is wrong with the circuits. Just imagine what could be achieved with such a technology. You are a real evil genius. But to be honest that is really impressive and it can surely find a really useful application.
Sounds incredible. I bet microwave engineers would love the ability to put conductive surfaces arbitrarily throughout 3D space, feels like another metamaterials video is just around the corner.
I came across a similar problem of a lack of specific information when building a zinc plating setup. It's not quite as finicky but getting good information was really difficult. I have scanned through quite a lot of available studies, footnotes, took notes from YT videos etc and even stumbled across a good book from 1900 (exact year) that helped me piece together a suitable solution. Turns out that the companies (doing electroplating) guard their exact mixture of bath, current and temperature fairly closely.
With that fancy dual laser setup you can even print the pads and stuff for components recessed, so you can more easily locate them for easier soldering, and also more easily pot everything in place to have a totally flat PCB with multiple planar layers, basically inlaying SMC's, really good for vibration damping because your whole board is monolithic.
Your videos are, without question, some of the best around. Regardless topic, subject, genre or target demographics. If you haven’t heard of this, don’t know how that would be, a nice gentleman released an open source SLS 3D printer. His project is called SLS4All. I thought that would be an awesome way of realizing your dichroic mirror idea without having to do a ground up design. I’ve been wanting to launch my channel with a project that kind of stands out and the SLS4All build is what I’m going to attempt. Because I want to see this project succeed, I hope content creators with the resources and experience, like yourself, take on the Sls4All project too. And , like I said, it would be a great way to integrate your 3D copper trace idea. Thanks for your time- Jason Burchell
Yes! 3d-printed parts with embedded circuits is something I have been dreaming about since I started my EE in undergad (over 10 years ago). The ability to 3d print some mechanical structure with circuits designed into the part opens up so many possibilities in robototics - which is what first got me thinking on this topic - but I bet there are a lot of applications that haven't even been dreamt of yet. Thank you so much for you content! I love your videos.
It was a pleasure speaking to you at open sauce. My suggestion to explore further and achieve 3d conductive paths on a ceramic medium would be a checkmate for diy pcbs. Imagine a fully routed qfp 44 MC the size of a poker chip! Show us the way Mr. Wizard!
With regards to your final point about "who would want to use this", I work in testing in consumer product R&D and the ability to integrate sensors, control, and wiring directly into the weird 3D printed jigs and prototypes I'm provided by various project teams would be a game changer. At the very least it would cut down on the wire and kapton spaghetti that everything seems to turn into the moment you start to assemble it.
I love the idea of wire harness/circut as part of the structure of an object. Car and ebikes come to mind as a super useful place for this, where aero dynamic, weight, aesthetic and manufacturing constraints really limit what can be done!
You Sir are impressive, I would recommend that you reach out to the company that gave you the tool that you’re working with in the video. I believe they would sponsor all of your needs in attempting the experimental idea you shared towards the end of the video. They as a company would find lucrative use for what you are freely sharing, still share it but have them provide everything you need in order to vet out the operational possibility and issues as you work through devising the final parts. Very impressive
If you could 3D print the traces layer by layer, you could make your own tranformers to any ratio, and even motors. You don't actually need permenant magnets for motors, you can absolutely use electromagnets for stator and rotor, it results in a really powerful motor actually...
He's not printing the layers, just an activating surface which copper plates to. So where copper is wanted fluid must have access. Impressive all the same.
@@kenmercer2721 He said himself he could activate it layer by layer towards the end which surprised me. I assume he's just putting a hollow cavity though, either way, it could still work. We print motor windings on transformers on 2D PCBs today anyway, think of what you could do with 5 or 6 of those with just some cavities so that the doping could still work.
Ganz herzlichen Dank, dass Sie nach langer Zeit wieder ein neues Video gemacht haben! :) Mit "SLS" hatte ich schon vor weit über 20 Jahren beruflich zu tun, dabei habe ich mich etwas in den "3D-Druck" verliebt. :) Die im Video vorgestellte Technologie ist sehr interessant! Beste Grüße aus Deutschland :)
The brief tangent about chat GPT is something I've encountered before from asking language models questions about my projects. Even if I know pretty well what I'm doing, the way you can get it to break down and explain individual steps and their purpose has helped me learn new things that weren't immediately apparent on numerous occasions. great video as always!
One thing to consider (other than chatGPT/LLMs) when optimizing experimental variables (such as your electroless plating solution) is using some kind of DoE (Design of Experiments) software. Although it probably wouldn't solve your problem here (since the order of addition was the important factor), it can be really useful for optimizations. Typically the software will suggest some different "factor levels" (or whatever it's called) to test, then you can enter your results, and it will suggest new improved conditions which you can test. It may require quite a few iterations, though, depending on the use case.
Super Fascinating as always. Sizzle focusing. That was some bowing with the hot air gun. 1n5711, what a great circuit. If only I was in a startup instead of an overgrown elephant of a tech company where security and H&S crush inovation this is just the channel to find those techniques that really work. Inspiring. Much appreciated Ben.
Back in 2010 I had been messing with a bunch of .5 mm LED lights and trying to get the soldering, wires and all the parts to be small and customizable enough to meet my needs. Maybe after seeing this some of the steps you are doing will make this project doable again.
As an electronics engineer, I'm really looking forward to technology enabling fully 3D PCB. This will completely change the way traces are laid out and will make designing electronics so much more fun!
BTW, every time you release one video like this in sandy or rocky terrain, like desert, first thing I do is go and buy some cold beer, sit in the couch and enjoy your videos, nice and relaxing ❤.
Really enjoyed watching this. I love how you clearly identified and explained the major issues you encountered. One thing i didnt understand is how you can plate an internal trace even if you activate it with a pulsed laser during printing.
I think this would be amazing for printing prosthetics, if you need to pick up electrical signals from where the prosthetic mounts to a location where a motor connects with signal processing build right in, or something like that.
I was a chrome plater. No one will help you learn. If you read the published manuals they just describe the process, little else. We carry our secrets to the grave. Congratulations, you are now one of us.
Fantastic as always Ben! I've had really bad experiences with chatgpt and technical questions (fea solver cards for example), so be careful! LLMs seen to be super confident even when they are blatantly wrong. Keep up the amazing projects!
This is fascinating concept, Ben. What you're describing is a way to build structural components with inbuilt wires and circuitry, thus building parts for a robot, say, that are multifunctional. Mind blown!
I feel like the failure rate will be astronomical if they are used in a structural way. A big advantage of having a separate PCB is the mechanical de-coupling from the structure so that stresses do not affect the traces as much.
You could mechanically decouple in this scenario too.I don't know if its possible to do print in place joints with SLS but you can make separate parts that snap together in some way.
An easy way to find focus is to let the reflected light scatter onto a light coloured surface; you will see a pattern of laser speckle which is an excellent indicator of focus, when the spot is well focussed, the pattern will become much coarser.
It's amazing to see how quickly new 3D printing technology gets into the home. By the way, I built a two-photon lithography tool from scratch that prints < 100 nm lines. 🤓
This video made want an SLS printer more than any normal review. I think you are on to an incredibly useful technique we will see a lot in the future especially when it comes to failure detection/prevention such as formation of cracks (or maybe even strain - at least over bigger surfaces)! Either as a continuity measurement or via monitoring the resistivity!
You can vary the distance between the ball lens and the collimating optic to change your focal distance. For concave surfaces make the focal distance about the same as the mean radius of curvature.
Very interesting. Could you possibly investigate the RF properties of the sintered powder? It would be interesting to see if ceramic powders with a binder could allow very robust antennas to be manufactured? My interests are for broadband antennas up to 20GHz.
Wow, I just watched a really helpful video about transistor switching circuits from 11 years ago. I was curious if you're still around, and I'm glad you are!
An cool idea with the integrated pulsed laser inside the Micronics would be to do multilayer boards. You could make hollow "arteries" to pump the copper liquid through for the copper deposit on the activated layer. This project is so cool!
In my academic experience I have noticed that many papers are quite similar to the previously published ones with slight modifications. The problem that GPT helped you solve probably was published in some of the first (oldest) publication on the subject and after that was dropped as considered "common" knowledge in this specific field of science. This conclusion is also based on reading a considerable number of science publications from the late 1800 and early 1900.
I think that’s right. When making up “physiological salines”, I always add weighed solid compounds (salts, glucose, taurine etc.) to distilled water and pH the (almost) final mixture with NaOH and HCl solutions. The exception is adding Ca which is done by adding CaCl2 solution slowly into stirred or bubbled solution: if you added solid or too quickly, calcium salts (phosphates) can precipitate out.
That’s really cool. You could have thick solid parts with 3D printed wires going through them. I guess they would have to actually be hollow pipes for the copper solution to get to. You’d probably also have to pump the solution through while plating to get proper coverage. Would love to see how far you could push that.
I'm always impressed with curved circuit board manufacturer. I have a 900R monitor and am using a Kinesis Advantage2 keyboard. I didn't realize antennas were created in this form inside electronics though. And yeah, we all have used LLMs for something technical that seems astounding.
I think there is good use to print parts with electronic circuits on them. From antennas integrated into cases to miniaturization by just getting rid of a pcb entirely and integrate everything into a case. However, for mass production we also need a plastic that can cope with the heat of smd soldering.
Now you can print a Luneburg lens for radar collimation. You could also print radar wave guides and feed horns. You could also print bifilar coils with exact lengths so that it is the perfect tuned tank of inductive and capacitive value for a specific frequency.
That dichroic mirror idea sounds AWESOME! Think of it as the Bambu Lab Automatic Material System - an add-on that will improve the capabilities of your printer. It'd need software support, but that could be a really awesome, albeit niche, addition to the printer, and move it into a realm that no-one else has gone.
The end pretty much echoed my sentiment at the beginning, while I can't really think of anything to use this for right now I feel like if the capability was easily available people would definitely find all kinds of cool uses for it
I wanted to implement sort of that process few years ago. But I'd chosen 355nm laser and different materials. I we built system and ordered custom galvo scanner from SinoGalvo and laser. But faced technical difficulties. I'm excited to see that process in real world! You are awesome!❤
Making small drones where the electronics are on the plastic body of the drone is an application of the circuit board printed on a 3d part. It would save weight and space for the drone, increasing available mass for the battery. You could also 3d print in place simple motors and solenoids for minor automation potentially with how tight you can get SLS, so you could print an induction motor in place with print in place gears for torque or speed adjustment that just needs to be plated and hooked up to a power source to make it work. I see a lot of potential with this process you are looking to create here.
You should reach out to my friends/former students at Rendyr. They’ve got a great mobile laser that can do some crazy cool things and still has a tiny footprint. I realize it’s not an sls printer, but it might be worth exploring for other ideas and applications and modifications you come up with in the future. Great video as always. So happy to see another one!

Did not expect this channel to be a part of this Micronics embargo that flooded my feed today but couldn’t be more grateful
lmao same
The only one that I'm gonna see, because I know for sure that it's gonna be the best of all.
I wish I could ban all the Linux channels from my feed to not see his and his team disgusting faces.
@@Ismsanmar actually I think Strange Parts’ second channel (Stranger Parts) had the best video on this machine, as far as actual product reviews go, of the 4-5 I ended up watching lol. I think this video is as much about the actual project as it is about the machine used to make it.
@@IsmsanmarWell, its been the least about this product so far... watch any of the other ones and youll see there is a loooot more to this whole thing
Focusing a laser projector "by ear"!? That would certainly not have occurred to me, but it makes good sense once you explain it!
Surprising, yes. But those of us with galvo lasers do this all the time. Solid way to get you 95%'ish there.
Seems like a cheap auto focus method, with some signal conditioning.
I thought only meth users could hear light. Guess I was wrong. Lol
@@AmericanMaking LSD also lets you hear light. And see sound. :)
@@NScherdin Tasting texture was my thing, haha. Smooth is sweet, velvet is citrusy, rough is bitter
It would definitely be cool to see a video specifically proving the idea of printing traces in areas that later aren't optically accessible.
but the "wires" runing thgroug the part would need to be tubes that need to have the loose material removed, so the copper can "collect" there
@@leobla744 Why tubes? They could be any shape, theoretically.
@@clonkex The traces at the very least have to run along the inside of some topological hole (e,g, tube) in the printed shape which is connected to the volume of plating fluid. Can't expect to make traces anywhere the fluid can't reach.
@@danielkruyt9475 Could we make the parts porous? The chemical bath would be an all day process as a result, but it could work.
@@heroslippy6666 My initial thought about the porous concept is, how do you clean off the dust? Ben mentions it as quite a critical step.
I used to run a Shipley 3000 PTH line, and we were adding a 500-1000ml of formaldehyde to the electroless (150 litre) bath every 3-4 hours to keep the plating thickness uniform throughout a production day.
Thank you for sharing arcane lore.
Was a pleasure meeting you at OpenSauce. Your approach to reproducing and improving these science and engineering results is second to none.
I was working on 3D printed electronics in my phd. At the begining I had similar idea that you presented in 16:20, but my problem was achieving copper in the whole sintered layer. Finally I ended up with FDM and precision dispensing with laser curing of MOD ink, which composition I developed myself.
This could make some great RF metamaterials.
Yep. Energy harvesting antenna arrays would be a cool application.
Time for someone to start making ebay grade RF spectroscopes in their garage.
I'm just interested in science in general and find this man to be an utter hero despite the world of intellectual gatekeeping around. A genius that needs to be recognized. Thanks for amazing videos over the years!
YT is weirdly interesting place. Not sure how did I ended up here, because this is not really field of my interests, but I found it fascinating. Not just the scientific part of it, but also the passion and creativity. People really have extremely wide range of hobbies. :)
Hey Ben! Glad to see youre still making videos!
Dude, if you could patent that idea of using a dichroic mirror to activate the catalyst as it prints, I bet you'd make a small fortune! You'd be a thousandaire in no time!
now that the information is public domain, no chance of a patent.
As usual, what Ben manages to achieve is amazing. These Micronics SLS printers look like they'll turn into a very good product, but I'd have been impressed if the video was just that he'd worked out DIY electroless copper plating, as someone who has wished he could do it before now. A more detailed video showing exactly how to do DIY electroless copper plating would be very nice! The fact that before anyone even has a Micronics SLS printer via the Kickstarter, Ben has already worked out how to hack one to make it print 3d circuit boards within prints is awesome.
This is the most criminally underrated channel on RUclips, dare I say. The amount of knowledge, skill, and time that goes into this should demand millions more views.
Perhaps if you expanded to partnering with someone to handle a mixture of marketing as well as someone who can incorporate some video illustration and distill some of this into bite-sized pieces of knowledge for the laypersons? Anyways, hope you're doing well!
This is awesome, I can see laptops where the case is the motherboard, leaving more room for battery and cooling and much thinner devices and so much more.
It's incredible how patents hinder progress across all areas. In the case of 3D printers, the delay was also because there were closed patents that were renewed for decades, until the companies eventually gave up as they couldn't find a viable business model. Once those patents were released, homemade 3D printers began to emerge worldwide. I didn't know that even chemical formulas were patented ... basically, we're in a dark age where large monopolies have appropriated all knowledge and technological development.
I had proposed developing a system of Cooperative Patents, along the lines of GPL licenses and open-source software, at a university in Argentina. But I didn't receive any support. On the internet, I saw that there's another person (Frederik Questioner) who tried to propose something similar with the Open Patent Office, but it didn't gain much traction either.
Excellent video sharing your insights.
I would support the initiative. Very little from google except a LinkedIn user account.
@@KallePihlajasaari What do you mean by 'support the initiative'? And what things couldn't you find on Google? Was it about Frederik Questioner or about my proposal?
@@jonidimo I am in favour of placing as many 'patents' as possible into the public domain. Specifically I would like to see unused patents be easier to licence or forced into the public domain. I would also like patents from companies that become insolvent or close down move into the public domain. Having a national patent pool that provides free or very cheap access to patents from any academic work or the above groups would increase the chance of small startups getting started and the more small business we have the less globalist monopolies we have. One provides resilience the other slavery.
I think I went looking for Frederic because you mentioned him. However you are just a random userid so there is no way to find what you have been working on so no point in spending too much time guessing.
This is fascinating. I like how you blend technologies in novel ways
I've tried to find a working electroless copper plating solution recipe before without like. Tried this today and I accidentally copper costed my thermocouple! I'm excited to have a working solution
This is a crazy cool technique that basically lets you do dual density parts and create electrical paths between them for creating wearables it basically means that you have a 3D printer but double and I think that's going to create some really interesting part
I think that we all hate the circuit boards that are covered in epoxy or something similar and then it is impossible to see what is wrong with the circuits. Just imagine what could be achieved with such a technology. You are a real evil genius.
But to be honest that is really impressive and it can surely find a really useful application.
Sounds incredible. I bet microwave engineers would love the ability to put conductive surfaces arbitrarily throughout 3D space, feels like another metamaterials video is just around the corner.
All this with individual effort and an enlightened mind. You are amazing
I came across a similar problem of a lack of specific information when building a zinc plating setup. It's not quite as finicky but getting good information was really difficult. I have scanned through quite a lot of available studies, footnotes, took notes from YT videos etc and even stumbled across a good book from 1900 (exact year) that helped me piece together a suitable solution. Turns out that the companies (doing electroplating) guard their exact mixture of bath, current and temperature fairly closely.
Well done, if you are able write up your findings and share the arcane lore with humanity.
With that fancy dual laser setup you can even print the pads and stuff for components recessed, so you can more easily locate them for easier soldering, and also more easily pot everything in place to have a totally flat PCB with multiple planar layers, basically inlaying SMC's, really good for vibration damping because your whole board is monolithic.
Your videos are, without question, some of the best around. Regardless topic, subject, genre or target demographics.
If you haven’t heard of this, don’t know how that would be, a nice gentleman released an open source SLS 3D printer.
His project is called SLS4All. I thought that would be an awesome way of realizing your dichroic mirror idea without having to do a ground up design.
I’ve been wanting to launch my channel with a project that kind of stands out and the SLS4All build is what I’m going to attempt. Because I want to see this project succeed, I hope content creators with the resources and experience, like yourself, take on the Sls4All project too. And , like I said, it would be a great way to integrate your 3D copper trace idea. Thanks for your time- Jason Burchell
Yes! 3d-printed parts with embedded circuits is something I have been dreaming about since I started my EE in undergad (over 10 years ago). The ability to 3d print some mechanical structure with circuits designed into the part opens up so many possibilities in robototics - which is what first got me thinking on this topic - but I bet there are a lot of applications that haven't even been dreamt of yet. Thank you so much for you content! I love your videos.
It was a pleasure speaking to you at open sauce. My suggestion to explore further and achieve 3d conductive paths on a ceramic medium would be a checkmate for diy pcbs. Imagine a fully routed qfp 44 MC the size of a poker chip! Show us the way Mr. Wizard!
With regards to your final point about "who would want to use this", I work in testing in consumer product R&D and the ability to integrate sensors, control, and wiring directly into the weird 3D printed jigs and prototypes I'm provided by various project teams would be a game changer. At the very least it would cut down on the wire and kapton spaghetti that everything seems to turn into the moment you start to assemble it.
I love the idea of wire harness/circut as part of the structure of an object. Car and ebikes come to mind as a super useful place for this, where aero dynamic, weight, aesthetic and manufacturing constraints really limit what can be done!
You Sir are impressive,
I would recommend that you reach out to the company that gave you the tool that you’re working with in the video. I believe they would sponsor all of your needs in attempting the experimental idea you shared towards the end of the video. They as a company would find lucrative use for what you are freely sharing, still share it but have them provide everything you need in order to vet out the operational possibility and issues as you work through devising the final parts.
Very impressive
Being able to print circuits through the body of a solid object could revolutionize circuit design.
If you could 3D print the traces layer by layer, you could make your own tranformers to any ratio, and even motors. You don't actually need permenant magnets for motors, you can absolutely use electromagnets for stator and rotor, it results in a really powerful motor actually...
He's not printing the layers, just an activating surface which copper plates to. So where copper is wanted fluid must have access. Impressive all the same.
@@kenmercer2721 He said himself he could activate it layer by layer towards the end which surprised me. I assume he's just putting a hollow cavity though, either way, it could still work. We print motor windings on transformers on 2D PCBs today anyway, think of what you could do with 5 or 6 of those with just some cavities so that the doping could still work.
Ganz herzlichen Dank, dass Sie nach langer Zeit wieder ein neues Video gemacht haben! :) Mit "SLS" hatte ich schon vor weit über 20 Jahren beruflich zu tun, dabei habe ich mich etwas in den "3D-Druck" verliebt. :) Die im Video vorgestellte Technologie ist sehr interessant!
Beste Grüße aus Deutschland :)
The brief tangent about chat GPT is something I've encountered before from asking language models questions about my projects. Even if I know pretty well what I'm doing, the way you can get it to break down and explain individual steps and their purpose has helped me learn new things that weren't immediately apparent on numerous occasions.
great video as always!
One thing to consider (other than chatGPT/LLMs) when optimizing experimental variables (such as your electroless plating solution) is using some kind of DoE (Design of Experiments) software. Although it probably wouldn't solve your problem here (since the order of addition was the important factor), it can be really useful for optimizations. Typically the software will suggest some different "factor levels" (or whatever it's called) to test, then you can enter your results, and it will suggest new improved conditions which you can test. It may require quite a few iterations, though, depending on the use case.
This is why I'm a Patreon supporter. Thanks!
Super Fascinating as always. Sizzle focusing. That was some bowing with the hot air gun. 1n5711, what a great circuit. If only I was in a startup instead of an overgrown elephant of a tech company where security and H&S crush inovation this is just the channel to find those techniques that really work. Inspiring. Much appreciated Ben.
Back in 2010 I had been messing with a bunch of .5 mm LED lights and trying to get the soldering, wires and all the parts to be small and customizable enough to meet my needs. Maybe after seeing this some of the steps you are doing will make this project doable again.
Love how it solves the focal plane issue AND opens up the capability to print through. Brilliant, thanks for sharing!
Dude this sounds amazing. This is the kind of enabling step that can open an exponential number of doors.
As an electronics engineer, I'm really looking forward to technology enabling fully 3D PCB. This will completely change the way traces are laid out and will make designing electronics so much more fun!
BTW, every time you release one video like this in sandy or rocky terrain, like desert, first thing I do is go and buy some cold beer, sit in the couch and enjoy your videos, nice and relaxing ❤.
By far the most interesting channel that I know. Great to get new content. Keep on trucking!
Really enjoyed watching this. I love how you clearly identified and explained the major issues you encountered.
One thing i didnt understand is how you can plate an internal trace even if you activate it with a pulsed laser during printing.
I think this would be amazing for printing prosthetics, if you need to pick up electrical signals from where the prosthetic mounts to a location where a motor connects with signal processing build right in, or something like that.
I think Ben has a background in medical prototyping.
I was a chrome plater. No one will help you learn. If you read the published manuals they just describe the process, little else. We carry our secrets to the grave. Congratulations, you are now one of us.
knowledge is for the people
@@thesquirrel082190 same as strap-on wearing goth GF in fishnets
Home-made laser lithography is highly impressive. 👍
Fantastic as always Ben! I've had really bad experiences with chatgpt and technical questions (fea solver cards for example), so be careful! LLMs seen to be super confident even when they are blatantly wrong. Keep up the amazing projects!
This is fascinating concept, Ben. What you're describing is a way to build structural components with inbuilt wires and circuitry, thus building parts for a robot, say, that are multifunctional. Mind blown!
This was straight sci-fi, you're making it a reality.
I feel like the failure rate will be astronomical if they are used in a structural way. A big advantage of having a separate PCB is the mechanical de-coupling from the structure so that stresses do not affect the traces as much.
You could mechanically decouple in this scenario too.I don't know if its possible to do print in place joints with SLS but you can make separate parts that snap together in some way.
This sounds amazing. Circuits inside a 3D printed part! I could see so many uses for that.
Dude that bit at the end is mind blowing
An easy way to find focus is to let the reflected light scatter onto a light coloured surface; you will see a pattern of laser speckle which is an excellent indicator of focus, when the spot is well focussed, the pattern will become much coarser.
Words cannot describe my excitement, and there is a kickstarter for it not completely sold out already? Done. . .
A workbench just got happier
Amazing Ben! Exciting work! Thanks for sharing
Glad that you're okay! Your videos are sought-after gems for many of us here.
It's amazing to see how quickly new 3D printing technology gets into the home. By the way, I built a two-photon lithography tool from scratch that prints < 100 nm lines. 🤓
Please share the details with humanity if you are able. Innovation shared breeds more innovation.
Also interested in details.
This video made want an SLS printer more than any normal review.
I think you are on to an incredibly useful technique we will see a lot in the future especially when it comes to failure detection/prevention such as formation of cracks (or maybe even strain - at least over bigger surfaces)!
Either as a continuity measurement or via monitoring the resistivity!
You can vary the distance between the ball lens and the collimating optic to change your focal distance. For concave surfaces make the focal distance about the same as the mean radius of curvature.
Wires INSIDE of a solid part is the space age future I want, can't wait to hear more!
Very interesting. Could you possibly investigate the RF properties of the sintered powder? It would be interesting to see if ceramic powders with a binder could allow very robust antennas to be manufactured? My interests are for broadband antennas up to 20GHz.
Wow, I just watched a really helpful video about transistor switching circuits from 11 years ago. I was curious if you're still around, and I'm glad you are!
An cool idea with the integrated pulsed laser inside the Micronics would be to do multilayer boards.
You could make hollow "arteries" to pump the copper liquid through for the copper deposit on the activated layer.
This project is so cool!
Bless you... it had been so long I saw suffering withdrawal.
Thank you for being.
WOW, internal copper traces - PLEASE MAKE THIS VIDEO - daaaamn. OK buying one of these.
In my academic experience I have noticed that many papers are quite similar to the previously published ones with slight modifications. The problem that GPT helped you solve probably was published in some of the first (oldest) publication on the subject and after that was dropped as considered "common" knowledge in this specific field of science. This conclusion is also based on reading a considerable number of science publications from the late 1800 and early 1900.
I think that’s right. When making up “physiological salines”, I always add weighed solid compounds (salts, glucose, taurine etc.) to distilled water and pH the (almost) final mixture with NaOH and HCl solutions. The exception is adding Ca which is done by adding CaCl2 solution slowly into stirred or bubbled solution: if you added solid or too quickly, calcium salts (phosphates) can precipitate out.
This guy is modding This thing already and it's still in beta. So awesome
You are amazing!!! For someone like myself, yours is the very best content on the web.
Great video, so much work going into this, you saying "see you next time. bye" is iconic!
The amount of information per minute in this video is just great, so much to digest
That’s really cool. You could have thick solid parts with 3D printed wires going through them. I guess they would have to actually be hollow pipes for the copper solution to get to. You’d probably also have to pump the solution through while plating to get proper coverage. Would love to see how far you could push that.
1 word. Awesome 👌
Best channel on RUclips, the only complaint is that you don't post often enough 😅
I'm always impressed with curved circuit board manufacturer. I have a 900R monitor and am using a Kinesis Advantage2 keyboard. I didn't realize antennas were created in this form inside electronics though. And yeah, we all have used LLMs for something technical that seems astounding.
This project could be one of those game changer ones!
I think there is good use to print parts with electronic circuits on them. From antennas integrated into cases to miniaturization by just getting rid of a pcb entirely and integrate everything into a case.
However, for mass production we also need a plastic that can cope with the heat of smd soldering.
Now you can print a Luneburg lens for radar collimation. You could also print radar wave guides and feed horns. You could also print bifilar coils with exact lengths so that it is the perfect tuned tank of inductive and capacitive value for a specific frequency.
That dichroic mirror idea sounds AWESOME!
Think of it as the Bambu Lab Automatic Material System - an add-on that will improve the capabilities of your printer. It'd need software support, but that could be a really awesome, albeit niche, addition to the printer, and move it into a realm that no-one else has gone.
That 3D printer augmentation idea sounds extremely cool. I hope you can make this work.
The end pretty much echoed my sentiment at the beginning, while I can't really think of anything to use this for right now I feel like if the capability was easily available people would definitely find all kinds of cool uses for it
Another amazing video project-writeup. Thank you so much. I genuinely get very excited whenever I see your channel has a new upload.
I wanted to implement sort of that process few years ago. But I'd chosen 355nm laser and different materials. I we built system and ordered custom galvo scanner from SinoGalvo and laser. But faced technical difficulties.
I'm excited to see that process in real world! You are awesome!❤
I think your solution for dynamic track creation is extremely worth pursuing and developing for commercial sale
It was only yesterday I was thinking we haven’t seen Ben for a while. And Today he appears. I think he’s built some kind of mind reading device.
One of the very few educational channels - Advert free - Thanks Ben.
Making small drones where the electronics are on the plastic body of the drone is an application of the circuit board printed on a 3d part. It would save weight and space for the drone, increasing available mass for the battery. You could also 3d print in place simple motors and solenoids for minor automation potentially with how tight you can get SLS, so you could print an induction motor in place with print in place gears for torque or speed adjustment that just needs to be plated and hooked up to a power source to make it work. I see a lot of potential with this process you are looking to create here.
Ah! Finally another video from Applied Science! Long time in the making ! Thank you sir!
Glad to see you posting videos again. I missed learning new things and trying projects.
You should reach out to my friends/former students at Rendyr. They’ve got a great mobile laser that can do some crazy cool things and still has a tiny footprint. I realize it’s not an sls printer, but it might be worth exploring for other ideas and applications and modifications you come up with in the future. Great video as always. So happy to see another one!
Not very often I'm truly amazed with videos this guy blown me away
FANTASTIC WORK
👏 👏 👏
These video journals somehow get better and better
Superb. So close to 3D printed parts with internal electronics: just add pick and place, copper/tin SLS.
