Can anybody tell me what type of machine is used to print food-safe, glazed ceramic? I found a video of how the process works, and it almost looked like a polyjet printer? But as far as I know the only way to print ceramic is with SLS (Selective Laser Sintering)... Sorry for asking such a technical question, I searched the site and FAQ for the answer and found this to be a very cool site but I could not find the answer to my question. I Thanks!
