I dont get this - you can just print with SMD paste and then reflow the whole thing at once - though you will need high temp materials to do that, but several amateurs have done it.
Afaik there are a lot more high temp UV resins you can print with.
- StingyJelly 6mo agoReflowing smd paste inside print won't work reliably as the solder will tend to form blobs instead of keeping the track shape
- Joel_Mckay 6mo agoI actually tried mixing in fine copper dust with fine SAC305 paste to create a non-liquid amalgam on re-flow, but the void/inclusion problem was worse than conventional SLS processes. Also looked at RF and metal salt processes, but it had more problems/hazardous-material than traditional laser setups. The core problem is making these machines safe and cheap to use. =3
