    Abstract: A three dimensional (3D) printer includes a substrate plate, a plate heater, a metal plate, and a multi zone temperature controller. The metal plate, adjustable along a z-axis, supports the substrate plate, and the metal plate is thermally coupled to the plate heater. The extruder is supported by a translation stage configured to move the extruder about an x-y plane, orthogonal to the z-axis, to positions above the substrate plate. The extruder includes a nozzle having a nozzle heater capable of heating the nozzle to at least 200° C.; and a heat tolerant filament drive mechanism to feed a printing material filament towards the nozzle. The multi zone temperature controller is coupled to the plate heater and the nozzle heater to independently control temperatures of the plate heater and the nozzle heater to facilitate extrusion of the printing material filament through the nozzle.
