Guest Curator Emmett Lalish has this to say about this 3DxMechanicals project: “This shows we’re well on our way to the holy grail of integrated printed electronics. Surely someone has realized that a 3D printer basically is a pick and place machine, right? It’s only a matter of time. I can’t wait to see non-planar electronics integrated throughout the volume of a 3D printed part.
This is a 3D printed circuit board that is the same size as a standard soldered perfboard. However it uses a conductive material for the conductive traces instead of copper cladding. Holes in the board allow component leads to be connected in printed channels that are later filled with a conductive paint or epoxy.
Details on the process can be found here.
