I made my own PCBs with a 3D printer
I love seeing DIY PCB manufacturing projects like this. Using the 3D printer as a plotter is a creative take on the traditional DIY process.For any aspiring EE hobbyists: Manufacturing your own PCBs is almost never worth the effort. You'll spend days or weeks getting the process and tooling right, and you still have to manually wire any vias that connect the front and back sides of the PCB. These DIY PCB manufacturing projects are fun if you're in it for the experience, but very impractical for getting work done. It's quick and easy to order small quantity PCBs online.OSH Park is a popular option: https://oshpark.com/#services You can get 3 boards in 9-12 days for $5/square inch. If you need the boards sooner, $10/square inch will get you a 4-5 day turnaround time. You won't save any money by buying all of the gear to DIY etch your boards, and you certainly won't save any time.
