OpticalShift research tool aims at angle-dependent colour on FDM prints
Grayson Carpenter, the developer of CMYKForge, has started OpticalShift, a research project for 3D printed surfaces whose colour and brightness change with viewing angle. Fine ridges in the printed surface steer reflected light, combined with CMYK colour mixing. The project is at an early stage and he is looking for printer and filament partners to test it.
