, I printed them right here on Shapeways, using their Porcelain material (and before that, Ceramic). Does that count as a "normal" 3D printer? Perhaps you mean something like a MakerBot. In that case no, it would be a bit hard to have the hardware and materials to print something like this at home. But it's easy to do it here! If you want to learn more about 3D printing, Shapeways is a pretty good way to do it -- they've got lots of great tutorials.
