3D Printed, Solderless Circuits

3d printed board

If you’re looking for yet another alternative to etching your own PCBs, then check out this new Instructable on 3D printing test circuits!

[Mikey] decided to try out this method when he needed a small board prototype. He designed the perfboard to have a standard thickness—only 1/16th thick (~1.6mm)—with thin, recessed channels on one side and through holes on the other. [Mikey's] circuit board allows you to stuff your components in, hold them down with a piece of tape, and then fill the channels with some kind of conductive material. In this example he’s used a highly conductive paint.

This 3D printed option probably won’t suit all your circuit-building needs, but it could provide an excellent shortcut for your next hack! As always, there’s a video after the break.
