When I was prototyping a bunch of CNC gear we'd routinely use wood to test with. It makes a terrible mess but an accident due to a misplaced comma will not result in missiles being shot through the room at high speed and the material is much cheaper. Also, your sintered toolbits will last just about forever.

When you work wood with metal tools you're going to have do a very thorough cleaning job afterwards because the acids in wood will wreck equipment quickly.

Thanks for the warning. I hadn't realized this problem exists.
