Prints with FDM printers without support structures (if you order it you may need to specify that) Other printer types should work too. No 3D printing materials are food safe for long term use, but it seems to be okay. I'd recommend at least washing it often, or to be safer you could boil it if the material can handle it. I use FDM PLA (on 3DHubs specify "Dishwasher Safe FDA Approved High-Temp PLA" as the material.
