If you’re searching for yet one more alternate to etching your own PCBs, then inspect out this new Instructable on 3D printing test circuits!
[Mikey] chose to try out this technique when he needed a little board prototype. He developed the perfboard to have a basic thickness—only 1/16th thick (~1.6mm)—with thin, recessed channels on one side as well as with holes on the other. [Mikey’s] circuit card enables you to stuff your elements in, hold them down with a piece of tape, as well as then fill the channels with some type of conductive material. In this example he’s utilized a extremely conductive paint.
This 3D printed choice most likely won’t fit all your circuit-building needs, however it might offer an outstanding shortcut for your next hack! As always, there’s a video after the break.
Unlike printing your PCBs on a routine inkjet printer, purchasing a Kickstarter robot PCB printer, etching your own, or modifying your 3D printer to extrude solder, this hack is most likely the simplest technique you can use—assuming you have the skills to make the 3D design as well as have gain access to to a 3D printer…
