If you can 3D print most of the parts for another 3D printer, why not also for a PCB mill? That’s the question answered by the Cyclone PCB Factory. It will help you kiss those toner transfer or photo resist days goodbye.
Homemade circuit boards tend to be rather small, which really helps keep the cost and scope of this project down. Most of the mounting parts, as well as the gears, are 3D printed. Of course there’s the usual machine tool items which you pretty much have to purchase: the ball screws, precision rod, stepper motors, and a motor to spin the routing tool.
Check out the video below to see where the project is right now. One of the crucial aspects of PCB milling is to have a level build table. The cutter head tends to be ‘V’ shaped so cutting just a bit too deep can blow out the traces you’re trying to isolate. The demo shows that this can automatically calibrate the software to account for any variances in the height of the copper clad.
