Abstract: A method of forming a 3D multi-colored object is described. The exemplary method includes two steps. The first step is forming the size and shape of the object using an extrusion process. The second step is applying a color to the object using a colorization process. An apparatus for forming the 3D multi-colored object is also described. The apparatus includes an object support, a first nozzle and a second nozzle. The first nozzle is for extruding a material that forms the size and shape of the object. The second nozzle is for applying a colorant to the object for coloring the object.

Abstract: A method of printing a three dimensional object in three dimensions using a starter substrate and rotational positioning is provided. The three dimensional printing method includes obtaining a starter substrate, coupling the starter substrate onto a rotating spindle, rotating the starter substrate about a rotational axis of the rotating spindle, and depositing material onto the starter substrate.

Abstract: A method of forming a three-dimensional multi-colored object is described. According to the method, molten base filament is used for forming the shape of the object. Before the molten base filament is deposited, colorant is added to the molten base filament to form a colored molten base filament, generally in the shape of a small colored slug. Finally, the colored molten base filament is formed into the size, shape and color of the three-dimensional multi-colored colored object. A nozzle for use with the method is also described.

Abstract: A vendor provides, and an operator obtains a method dedicated printer bundle. The printer bundle includes a printer having a key interface, an ink supply, and a key for association with the printer through the key interface. The key is provided with key data pertaining to an authorized page count. The printer operator is allowed to acquire additional authorized pages as needed. When the printer ink supply becomes depleted, the printer operator is provided with additional ink at no or insignificant cost.
