Powder coating composition system and process

A system for fabricating a colored powder coating composition from a plurality of solid input filaments, the system comprising:

• a filament feeder comprised of a plurality of filament drivers;
• a single-color filament associated with a first of the filament drivers;
• a functional-input filament associated with a second of the filament drivers;
• a filament mixer having a first filament inlet joined through a first inlet channel in a mixing chamber housing to an interior mixing chamber;
• the filament mixer having a second filament inlet joined through a second inlet channel in the mixing chamber housing to the interior mixing chamber;
• a portion of the single-color filament located in the first filament inlet;
• a portion of the functional-input filament located in the second filament inlet;
• said mixing chamber housing having a heating element and an extrudate channel between said interior mixing chamber and a nozzle opening of the filament mixer;
• a mixing mechanism within said mixing chamber;
• an extrudate receiving platform for receiving extrudate deposited from the nozzle opening;
• an extrudate powder mill for milling solidified extrudate received from the extrudate receiving platform;
• and
• an electronic fabricator controller in communication with the filament feeder and having a fabricator processor, a fabricator memory, and a fabricator bus.
