System and method for on-demand colorization for extrusion-based additive construction

摘要

A color 3D printer and its method of use are disclosed. The color 3D printer uses a number of chambers to dye a filament to a given color. This colored filament is then extruded, pursuant to an associated 3D model of an object, to produce varying colored physical objects, on demand, with the use of a single filament and a single print head. Further, the color 3D printer features a waste management apparatus which provides a number of ways to dispose of waste fluid.
