The robotics club I mentor (Parallel Universe) has a few different 3D printers, and print all kinds of custom parts for their robots. An alumnus of Parallel Universe founded the company "Formlabs" that makes 3D printers, among other endeavors. My son worked there for a time.
For obvious reasons, I have no way to get pictures of the printers themselves. But here is a picture of a 3D printed part that my son has sitting on his night stand. I'm not sure exactly what it is supposed to be, but if I had to guess, it is a rook to a chess set.
