Final PCB

Group assignment

Fabio has a nice description of our PCB milling machine on its website.

3D printed board

As an electrical engineer, I make PCB for more than 20 years.
I started using chemical etching. 10 years ago, my department acquired a PCB milling machine.

With this experience, I decided to try something new: 3D printed PCB.

I saw several videos of people using a 3D-printer to make PCBs.

I decide to try a method using copper foil tape on 3D print board.

Design procedure

First step is to design the PCB. I used KiCAD to make a simple board, inspired by the QPAD:

Next, use File/Plot... to export the PCB as a svg file:

plot dialog box

  • Uncheck Plot drawing sheet, we don't need it
  • Select Actual Size for Drill marks, to have the correct size for the holes
  • Click on Plot
