Diegel is professor of mechtronics at Massey University in Auckland, New Zealand and has a passion for 3D printing. His designs – Scarab and Spider electric guitars blur the line between art and mere musical instruments. They are 3D printed in alumide and polyamide on an EOS Formiga P100 selective laser sintering machine. Both guitars can be fitted out with any selection of neck and hardware by modifying the geometry to suit. If someone wants a certain brand of pickup the guitars can easily accommodate any changes.
