I have been having trouble finding a way to prototype waterproof parts - this is one of the original reasons I purchased a resin printer, but I am now finally testing it! I used the resin printer to print a sphere with a 0.200" wall and a 0.25" neck wall thickness and tested it to 90psi to see if there were any air leaks. Please comment and let me know what you think or what I should try next!
Here's a quick video showing most of the build process for the mechanical components of the Buster Beagle MK3 DIY Desktop Pneumatic Injection Molding Machine.
