Muriatic Acid Etchant PCB making

thingiverse

hi, this is a new version I recently gave to my friend for testing. This setup is what I call a PCB bath with an acidic etchant. Generally speaking, it's used for making PCBs. For example, take a look at this instruction: http://www.lvl1.org/2011/05/03/toner-transfer-and-muriatic-acid-etchant-making-pcbs-at-lvl1/. I recommend printing with ABS and using a vapor bath to ensure air tightness. The middle section of the setup is for acid, while the rest is used for hot water to raise the temperature. To make it work, you need to place three pieces of clear acrylic, each 10 cm wide, and glue them together with something like silicon. Next, connect an air supply to both intakes. Make sure the holes are large enough to allow air to flow through the acid. I created two versions because of the print time - a smaller one can be used in another container or on its own if desired.
