Abstract: A three-dimensional printing system having a generally planar object platform that is rotatable about a central point is disclosed. A printing extruder nozzle is disposed above the platform and configured for radial or linear movement relative thereto while the platform rotates. The rotating platform may include an electromagnet configured to attract magnetic flakes within the material extruded by the printing nozzle. The printing nozzle may include a multi-heater having two or more heating units configured to incrementally heat the printing material from room temperature to the target extruded temperature.
