Color fused fabrication

Currently, filament printers cannot truly reproduce colored objects and the best present techniques rely on a form of dithering exploiting occlusion. These techniques are only demonstrated for shades of two base colors that behave differently depending on surface slope. IceSL provides a novel 3D color printing method capable of creating controlled gradients of varying sharpness.
