Custom printed circuit boards have become more and more accessible to the average hobbyist over the last decade. But one problem still remains: your circuits will take at least a couple days to make.

Conductive filament exists, but it takes more than that to 3D print something like a circuit board. The main issue is that traces made from conductive filament are basically resistors; they don’t act ...

These unusual problems can derail your 3D printer projects, including filament clogs, brittle material, faulty thermistors, ...

Effective printed-circuit-board cleaning requires special fluids, tools, and methods. Here are some of the most common to use and to avoid. How to effectively clean and dry printed circuit boards at ...

Pentel N850 marker was the best photo resist, ferric chloride etched away the rest very cleanly.
