3d-printed (or even 2d-printed) electronics apparently is already a reality, but to what extent exactly?
The basic conductive paths of a PCB can now be easily made even by amateurs, but you still have to mount the actual components to make it work such as resistors, capacitors, transistors, leds, etc.).
However, if you take a look at the link, and pic related, apparently we're already at the point of being able to print all of that stuff, and even entire displays just the way we would print a normal paper flyer; also, from the 2nd link: "A very wide range of inks can be utilized enabling a full range of printed electronics functionality: conductors, semiconductors, dielectrics, resistors and more."
This made me think... how close are we to the point where we could literally print an entire PC's electronics using a single multi-material printer and no additional mounting required (aside from the microelectronics components like the CPU, which for obvious reason cannot be made with a regular printer)?
What are the parts that we still cannot do and why?

sorry, wrong pic

What's the advantage vs just using a pnp machine? I imagine it's easier to make a resistor than to make some kind of material that a small machine with limited power can turn into a resistor. 3d printing empty pcbs are cool but you can make those at home with a little bit of investment too.

Why wasting time individually manufacturing all the countless components and then placing them all together when you can simply print the entire thing in 1 go?

Because you replace that problem with manufacturing the various materials needed to feed the printer, and designing a printer that isn't the size of a factory to convert these materials into working parts. Its a much harder problem, and thus much more expensive than simply outsourcing it to a Chinese factory which churns these out by the millions.

Because mass manufacturing standards goods in large quantities give an economy of scale. Printers are the best tool when you want to create a small number of unusual items, factories are the right tools to produce cheap things in industrial quantities.
Imagine printing one million newspapers on small printers.

That "problem" exists regardless, electronic components aren't manufactured out of thin air
>and designing a printer that isn't the size of a factory to convert these materials into working parts.
I doubt the stuff depicted in pic >>79412 required a printer the size of a factory
>>79444
You could say the same about literally every kind of product, not just electronics; but commercial 3D printers for self-production still exist. That's what I'm interested about, not economy of scale or mass-production.

3d printed hardware would open up a possibility of 100% FOSS hardware, with a fully FOSS environment. Get the files for printing hardware, then print whatever chips you want.
Probably hilariously slow and large compared to the contemporary mass-market chips in any given era, but great for security because it'll be a lot harder for glowies to sneak in their management chips and whatever else most chipsets are plagued with nowadays.

>that problem exists regardless
yes, this theoretical device would not solve any real problems; it would just change the extant sourcing problem to a different sourcing problem.
3d printed electronics sounds cool and maybe would be in a couple niches, but I think for most uses it would be far nicer to have a home PCB manufacturing device and a P&P machine, which could be combined into a single product. P&P does not depend on the establishment of a second supply chain for the production of probably non trivial 3d printer filaments (non trivial if they're any good that is), but can just use the existing and well developed component industry. And dont go telling me resistors arent open source and therefore botnet. Go take a shower

I think 3d printing resistors etc. could be useful for prepper/survivalist scenarios
>inb4 just hoard some of every type of resistor/capacitor in existence
Roger Pollack · 2024-08-28 13:28
I have a book in my library called "Makers", I haven't read it but the summary claims that a fourth industrial revolution is about to begin and it'll be over the common person having the means of industrial production in their own homes for very cheap through things like 3D printers, laser cutters, whatever. This thread reminds me of that book, so yeah. hi

I mean with basic electronics skills you can take smaller resistors and make them into any amount you want. For survivalist scenarios you either scavenge or use anything conductive you can find and cut it to length.
>>79566
If this means includes physical space, I doubt it. Most people don't even own one to live in.

Could inkjet 3D-printing be the solution?
>"The 3D inkjet printing process is similar to other 3D printing processes in that it proceeds through layer-by-layer deposition. Printing instructions in each layer are generated from a 3D mechanical model for your product, just as is done with popular fused deposition modeling (FDM) systems. However, this established additive manufacturing process is unique in that it is adaptable to a wide range of liquid materials or solid suspensions, providing conductive or insulating structures with high printing resolution. Compared to processes that involve the fusion of metal or plastic materials, inkjet printing requires no post-processing—the finished printing product will be fully functional as soon as it leaves the printing system."
