[@Acecool]

Actually, sooner. You can make a 3d printer do exactly this. There are already injector extruders available, and so on... this thing isn't worth $400, let alone $4000.... Ugly finish, etc... I can get just as ugly a finish with protoboards, and for connecting surface mount components, I just run traces around and don't cross... Or, simply run thin wires and a bit of adhesive to get the same result for prototyping.

Hi, Bro! I saw a random guy the other day on KZbin, and his process is intuitive. 1. He hand-sketched on the board. 2. Made appropriate drills. 3. Then he laid very very thin wire along his sketch. Then, he put that whole PCB carefully on a surface which he can increase the temperature (he used an iron box). Gradually as temperature increased, wires began to melt and the wiring thing was done. That was cool.

This is a really fascinating review, very in-depth, and we learned a lot watching you use the tool! Thanks so much for taking a look at our technology! You're absolutely right that our customers are more often professional electronics engineers looking to quickly validate ideas, do rapid solder paste dispensing for SMT components on short runs of factory-fabbed boards (something you didn't really do here because you prefer hand soldering) or work with flexible/stretchable substrates where an additive approach is required. We also have a lot electronics designers looking to test/validate their own custom conductive ink formulas among our customers, because you can easily swap different cartridges of ink into the machine. As you point out, we've had a large number of universities purchase if they're looking to work with exotic substrates, or to teach the fundamentals of electronics by having students see circuit designs come together before their eyes.

[@ytc3182]

[@HypherNet]

If it could do auto-riveting, board flipping, solder-paste dispensing, flying probe test, pick-n-place, included an oven, and flying probe uC programming, it would be really cool. Though I doubt using ink is really the right approach. Using a more traditional etching process with a laser or something similar would be much better in my opinion. You could totally sell a machine that took in parts, blank boards, and spat out fully functional and programmed 2-layer boards ready for testing. Probably could sell that for $20k. But until you're at that point, I just don't see the value proposition compared to the Chinese board houses.

[@absurdengineering]

... and filled the blind vias for you, and added a tool for extruding on the hole walls and curing it there (with a pin sticking out the middle of dispenser to keep the hole open). The board would need to be heated for that so that the ink on hole walls would cure so that the head could move to the next hole without disrupting current one. … and used a smaller nozzle, and had the ink stick less to the nozzle… In other words: this is good for proof of concept and for someone’s pet niche application where the current resolution and process would work unchanged. For most other people with money for it, this seems like a waste of time though. I wouldn’t be able to use this even if it was given to me for free. OTOH, a sturdy CNC with total component cost in the same price range would have immediate use. I could run two boards in parallel. CNC is also great for doing controlled impedances on thin two layer boards, or even 4+-layer boards if you can press the stack yourself (takes a press, among other things). On a CNC, you can tweak the trace width with the VNA plugged into the circuit, and do trim runs until it’s within a fraction of an Ohm, if you want it that way (not normally needed). You can also do EM-model-free feature routing, where instead of using very expensive software that still takes you only so far, you run a shape refining algorithm that modifies the shape incrementally to produce the exact response you want - and both the VNA and a TDR output can be used for that. You can do this with other components already in the circuit as well, and after the dust is blown off, you power it up, g-code generator takes a frequency and time domain sweep, circuit power is removed, and the tool goes back for another refining run to bring it closer to what you need. You could design some very complex filter responses and feedback paths that way, with rather simple technology, without slaving yourself away to EM tool vendors (OK in a big business setting, not so much in small startups and for advanced hobbyists). This can easily pay for a very fancy CNC just in the cost saved by not paying a fortune for EM modeling software, and for the speed of iterations. A bit of ingenuity can really take CNC techniques way further than is typically talked of. I’m sure plenty of companies with clever people may do this already and keep mum for competitive advantage; but I just do it for hobby stuff and would love it if some manufacturer just took the idea and made a cheap widely copied machine + software combo that can do the sort of CNC you don’t see done on PC boards. Commoditizing this stuff would be more than awesome. I only mess with it because I have to - otherwise I couldn’t play with microwave circuits so easily, and am not interested in product development in this area (life is too short - can’t do everything). I like physical experimenting too much - dealing with accurate numerical EM models for a hobby is not my piece of cake. So, all in all, this is not a very innovative product, because it does something that 99% of people who do these things can think of in like half a minute, and it doesn’t even do it particularly well (about anyone in this field could take it to this field - but that normally in business setting is a proof of concept, not something you dump onto the market with fingers crossed).

[@xaytana]

DIY would be stupidly easy. Nothing about this is sophisticated at all, just the changeable tool platform is a bit unique in that it uses pin to pad as a connection method, and that the bed works as a workpiece clamp and the curing heater. The only other non-standard thing is the screw-based plunger extruder for the ink vial, but this isn't anything difficult to implement. The drill itself is so unsophisticated that it uses a literal RC hobby motor to run it. Take any typical 3D printer, add a clamping system to hold a PCB blank to the bed, and have a a changeable tool system. The plunger extruder would work off the filament extruder's functionality but at a different feed rate depending on the gearing between motor and plunger. The drill could probably run off the extruder's functionality as well, but implement it as a switched function where a constant feed rate has the drill as 'on,' and stopping the feed rate switches it to 'off,' with a simple amp to run the DC motor. You could probably even upgrade the tool changer from a manual system to an automatic system. The only sophisticated part that would need work is the probe function, as most closed-source printers won't integrate it nicely unless a probing system is already provided, resulting in the probe being entirely separate and integrating at the design software level, or there's a chance more open-software products would allow it, with open-source platforms being the most open to this modification. But with that said, is probing actually necessary? Most 3D printers are going to be level for proper printing anyways, and the clamping system should be sophisticated enough to keep relative flatness of parts, even with the PCB floating in relation to the bed; even hobby milled standoff clamps should be toleranced well enough as long as the hobby machinist knows what they're doing. As for positioning purposes, I would think a laser pointer would be a valid replacement, and would be an entirely passive tool. This only leaves curing. I'd recommend and oven as no typical 3D printer is going to have a bed that safely achieves the 210°C requirement. Heated beds for ABS only really achieve >100°C due to going above the glass transition temperature of 100°C isn't really recommended. A heated bed that'll go to 210°C is a modification that is possible, but at that point it's probably safer to use an oven due to burn hazards on an open surface. The only big issue is the consumable that is the ink. I'm not sure how many suppliers there are for this stuff. Though I do wonder how similar it is to solder paste that board manufacturers use for SMD soldering; seems like it'd be similar stuff, high silver lead free paste, just the 'ink vials' use a much finer syringe tip. There may also be some kind of etching agent, or something in the reaction while baking, that adheres the paste to the fiberglass of the PCB; though I'm not sure how soldering paste interacts with a raw PCB without solder mask, as SMD soldering always has a solder mask on the etched PCB, there may not be a need for any method of adhering the paste to the board. The paste is the big unknown, and the cost of the Voltera pastes makes an alternative solution worth looking into. On the topic of conductive consumables, we've also seen actual conductive ink, as in pen ink, and we've seen various forms of filament that're metallic and conductive once you bake off the plastic. I don't think finding a product between the two would be all that difficult, especially as solder pastes already exist in various recipes. Unfortunately, Voltera doesn't list the metallic recipes for their inks, though they do for their various solder pastes. All of Voltera's products also require refrigeration for an 8 month shelf life, which makes this entire system even more expensive given that each vial is only 2ml. Only thing left is the rivet tool, probably the least sophisticated tool here, as hollow rivets have been a thing for a long time and are mostly understood in how they work. At the end of the day, the conversion is simple, with a simple manual tool changer, and simple code hacks to make it all work, with the biggest issue being the cost of OEM solder pastes and the need to find an affordable alternative. All of this is also true for converting a CNC mill, though you'd need to make more drastic changes to how the tool functions to get that platform to function correctly, as exchanging extruder type A for extruder type B is fairly simple and could easily be a 1:1 exchange in coding, but adapting a mill would be like adapting the mill to a 3D printer first before adapting it to a PCB printer. All of this is easily achievable, it's just the damned ink that makes the DIY project expensive. But does anyone really need a PCB printer? PCB printing services are extremely affordable, with some having decent turn around times, not to mention those services can do everything a PCB printer can plus more, considering those services can also do multi-layer boards. Even DIYing a double sided board isn't that difficult, though chemicals involved may produce safety hazards, but a simple masking and etching setup is extremely cheap in comparison to a machine with a high cost consumable ink. While a cool project, I just don't see the point of it. Need a prototype board? This is what we have perfboard for, or even better, just use a breadboard until an order from a PCB service arrives. There is literally no logical explanation for PCB ink printers to exist, other than being an expensive toy for people with more money than brains. I can't find a single use case where this machine has any advantage over what we already have and already use; especially when the consumable has a shelf life that requires you to actually produce a decent volume of boards within that time frame.

The printer would become cheap and easy to get, if the concept was succesfull. But the main problem lies in the conductive inks. These have been around for decades and didn't get cheaper by any means, ever, mostly for the expensive resources needed.

Great demo video, thank you. I was very interested in this printer until I saw the horribly poor quality result. Maybe good for extremely simple boards, but if you're doing enough to warrant a PCB printer you're probably not always doing super simple designs. After seeing what it did with his design, I shudder to think how it'd print out even a simple 32 or 48 pin mcu design. Add the price tag to that and this is just not for prime time.

Having to buy proprietary consumables is an instant red flag. Especially for that price. It really wouldn't be that hard to make something similar for a considerably lower price.

This product is kinda dumb, in the same time this takes you can print your circuit on a transparent film, expose a photosensitive PCB with UV, develop it and etch it with ammonium persulfate or ferric chloride.

I have a lot of experience working with the voltera and the nscrypt 3d printers from an internship. The voltera is very nice for printing on flexible substrate and can tolerate using a variety of approved and non-approved inks. You can make your own inks that have properties you want and you can load them into the voltera using lurelock connections.

We have one in our lab. It's nothing like the PCBs you get from JLCPCB and the ink is pricy. It can print on flexible substrates and that is really handy. Prototyping flexible electronics can be costly, and while Voltera can't do fine pitch, is a great prototype tool.

Hey could you maybe make a video about how to get all the parts for starters? I especially mean ICs, Mosfets, Capacitors ect. You often have huge part lists under your video but it's somehow awkward to buy all of them single or a bunch of lets say 5 ICs of that type, 10 Mosfets of that type ect. Especially for new ones this can be quite tedious because we all don't know what to use where. I bought a few boxes of sortiments for ICs but I am never sure if it contains the right ones I'd need for a project... So what sortiments of components would be the best for a broad range of beginner projects? Would be cool, thanks!
