Michael Hebda is a University of Bradford student who has come up with a design for a unique multi-color 3D printer. It currently has the ability to print with 3 different strands of ABS filament through one nozzle. The nozzle has a mechanism for switching quickly between these filament, allowing for multi-color printing on individual layers.
