Color (Or should we say 3D print) by Numbers

Kurt Hamel is an engineer, builder, maker, hacker and “mad scientist” from Providence, RI, who uses his skills at 3D printing to create some interesting objects and techniques. A member of the Ocean State Maker Mill, Hamel has won some first place prizes in challenges sponsored by MakerBot and GE, and now he's taken on the task of updating and modernizing the venerable paint-by-number kit with a method of using his 3D printer to build multi-colored prints. By working with the extrusion heights of various parts of a print, it's fairly straightforward using his method to create multi-colored objects using a single-head 3D printer.
