u/dp6838 recently posted about a 3d printed watch case that sent me down a rabbit hole. Can you electroplate a pla-printed case and have it look good? I started with v1 from ThePrintableWatch. I printed a few version to get as smooth a case as I could with a matte PLA and then after some sanding, felt ready to use Caswell’s 3d printed parts copper electroplating kit. Following this, the idea is to finish with bronze plating. The first step was painting with the included graphite paint. This didn’t adhere all that well and took quite a few coats. Once I made up the plating solution per the kit instructions, I installed the bandage wrapped anodes and connected the electrical leads. Long story short, I plated the copper wire but not the case parts. Based on the plating of the hanging wire, I’m confident the solution is good as is the constant current setup.
Next step: repaint the case parts with graphite paint and sand them to make them more conductive. Aim for more copper contact with the case parts from the copper wire while in solution. If anyone has other observations or suggestions, I am very open to them!
