2x Stronger Resin Prints with Electroplating [video]

Most of the "copper electroplating" videos on youtube are pretty good introductions, but there are two things to keep in mind: first, most just use a 9v battery or similar, which is not a great idea. Better to use a current-controlled source. I use a cheap bench power supply and limit the current to 100-500mA to start, only increasing up to 1-2A after a while (and if I want more plating). Voltage can float at whatever level, as long as it's <5v or so

Second, a lot of YT videos use safer, non-acid mixes. These will work, but not nearly as well as acid copper baths which include sulfuric acid. It's not too bad as long as you're careful while mixing, and despite being low pH the final solution is not terrible if you get some on your hands (mildly irritating, wash it off. Wear gloves though!)

An example acid bath that's pretty decent recipe: https://www.youtube.com/watch?v=yvW5mWbUbU4
