So I am a beginner 3d printer who just had his first class at a makers space. I have some 3d modeling experience. My idea was to get an aquarium with my friends, and to practice my 3d printing wed all pick some simple things from our favorite games and print it for the fish tank decor. Simple things that don’t need painting like the n64 logo. When I brought this up the class however, the teacher said that filaments are full of toxins that would kill the fish, and his modded rigidbot does not support a filament that would not have toxins in it.My question to you guys is, is there a way around this? Is it possible to purge the filament of its toxins somehow, or seal it so that toxins do not leak?A quick Google search did confirm the level of toxins, but I didn’t see any work arounds for my project as it is a pretty niche project.Edit:You guys have been super helpful, thanks for the advice. http://ift.tt/2o1vbfg
