PCB Etching with 3D Printer Agitatior

thingiverse

I crafted Tech2C's Pen holder on Thingiverse, specifically #2459624. I utilized it on my Milling machine to apply sharpie ink as an etch resist. A video demonstration can be found at https://youtu.be/vKqAf8pkKJ0. Next, I employed my 3D printer to heat and agitate the Ferric Chloride solution with the PCB in it. The GCODE commands used were: g1 y0 f4000 g1 y50 g1 y0 f200 g1 y50 Multiple copies can be made; execution takes approximately 15 seconds. Sample PCB traces produced using this technique are visible. To achieve optimal results, increase the overlap of sharpie lines and print twice to ensure a good resist. Thin lines were printed with one layer of sharpie; they worked but got slightly undercut. A video showcasing the process can be seen at https://youtu.be/UFc9t4WyRU4. I discovered that setting my bed temperature to 100C kept the Ferric Chloride solution below the recommended 55C maximum, which is beneficial for my thick plastic tray. If anyone has a reliable method for importing PCB gerbers into Fusion 360, please message me or comment on this thing.
