Hello! I was thinking of making some piercing designs, mainly for personal use since I cannot find that I like in the market. So I was thinking if there are any materials I could use. Plastics, stainless steel and sandstone are out of the question. But what about ceramics? They are food-safe, pretty smooth and (from what I've seen from pictures) they are not porous at all. Are they suitable though to.. .stick them in my ear? The minimum wall thickness is 3 mm, but this is not a problem because I wanted to make piercings thicker than 3mm anyway. So if I avoid sharp edges I don't think that I will have any mechanical problems. Glass is another candidate, since many piercings are made out of glass, but I don't think that 3D printed glass would work. It is porous and fragile, so it is neither hygienic nor has the desired mechanical strength. Any thoughts?
