Abstract: The invention, and all of its embodiments, is a 3-D printer that utilizes one or more extrusion screws to process any given material including, but not limited to, plastic, metal, composites and non-metals to build 3-dimensional objects. The processed material is deposited on a moveable platform via force from the extrusion process. Motion is numerically controlled via a computer and one or more motors. As the extruder deposits material, a platform or the extruder is moved in one, two, or three dimensions at a predetermined vector. Once a layer of the object is created, the distance between the extruder nozzle and print surface is increased and the process is repeated until a three dimensional shape is created.
