Through his company Odd, professor of mechatronics at Massey University Olaf Diegel is selling 3D-printed nylon-bodied electric guitars that one "could throw [...] against the wall without worrying about it breaking."
Diegel is an exponent of 3D printing. His zany guitar bodies are created using computer-aided design (CAD) software, output in one piece on an EOS 3D printer. This is the new world of additive manufacturing.
"The old style of [subtractive] manufacturing is you start with a block and cut away the material you don't need. With this you start with nothing and add material one layer at a time until the object is finished."
The process is a little like inkjet printing, but instead of ink squirting out of the print head, successive layers of plastic or metal powder are deposited according to the CAD file's instructions
