Comment on DissolvPCB enables fully recyclable 3D-printed circuit boards with liquid metal conductors
nesc@lemmy.cafe 1 week agoIt looks good for prototyping true and makes the whole thing easy to disassemble and reuse. As for safety and size concerns I think they are pretty similar with 3d printers and etching. PVA is far more expensive, starting from us$40, while copper coated fiberglass panels cost <$1 per square meter. It really looks like a great process for learning institutions/kids I wouldlove ro try it it at least once. 🙃

It’s around $40 for a spool, I’m not sure what that works out to per square meter of printed board, and I’m far too lazy to work that out.
It also seems to me like it could be a more efficient use of board space since it could be printed closer to the shape of the traces than you’d probably want to trim a board to by hand so you can save on material a bit that way. A bunch of cut corners and notches cut out of a few boards could add up over a few prints.
I’m just spitballing some thoughts, I don’t do nearly enough circuit designing to have a horse in this race, nor the desire to really work out the economics of it but especially for someone who already owns a 3d printer and maybe is already using PVA filament this seems like something that could fit well into their existing workflows.
