Re: Homemade Circuit Boards

Most people who are doing at-home PCB etching are now using Vinegar for the etchant acid and Hydrogen-Peroxide as an accelerant.? This seems
safer and easier on the environment.? Thin it with water and flush the dilute solution after using it.? Of course you still need to use appropriate safety
precautions.

Just wondering...has anyone tried using a 3D printer to print the resist pattern on PCB material? I think it could be done but I don't know if the print filament material would resist the etchant well enough. Even the cheap 3D printers like I have can do some pretty high resolution prints when set up properly...maybe not good enough for some of the really tiny surface mount ICs but then they're too small for me to solder anyway. ;) Mutli-layer boards could be a challenge as well. Might be an interesting experiment.
Is the ferric chloride etchant still available these days or has it gone the way of other things we used to use but now are considered hazardous materials?
