Direct color 3d printing coloring and additive material technology

An apparatus comprising:a filament feeder comprising a filament mounting bracket, a roller, and a filament motor, the filament motor configured to rotate the roller to feed the filament into a chamber of a three-dimensional ("3D") printer, wherein the filament mounting bracket is mounted to the 3D printer above the chamber and wherein the 3D printer is modified to comprise a filament opening corresponding with the filament mounting bracket;

• and
• a controller module configured to signal the filament motor to feed the filament into the chamber of the 3D printer.

An apparatus comprising:one or more color dispensers, each comprising a hopper, a color auger, a color auger motor coupled to the color auger, and a vibrating motor, the color auger motor configured to rotate the color auger and feed powdered substance from the hopper out a nozzle into a chamber of a three-dimensional ("3D") printer, wherein the vibrating motor is configured to vibrate the color dispenser during operation of the color auger of the color dispenser;a mounting bracket comprising a nozzle opening for three color dispensers, the mounting bracket configured to mount to a side of the chamber of the 3D

• printer, wherein the 3D printer is modified to comprise a chamber opening corresponding to at least each of three nozzle openings;
• and a controller module configured to signal each color auger motor to rotate to deliver a prescribed amount of powdered substance to the chamber of the 3D printer, wherein a main auger of the 3D printer mixes the powdered substance with printing material to color the printing material and/or to add an additive to the printing material,
• wherein the controller module is configured to interface with executable code of the 3D printer, wherein the controller module provides a graphical user interface ("GUI") comprising fields configured to be modified by a user to program color information for various parts of an object being printed.
