  • Color switching for three-dimensional printing
    Patent number: 10022917
    Abstract: By reversing the direction of a first build material fed into an extruder, the first build material can be wholly or partially evacuated from the extruder before a second material is introduced. This approach mitigates transition artifacts and permits faster, more complete changes from one build material to another.
    Type: Grant
    Filed: October 26, 2015
    Date of Patent: July 17, 2018

  • HEATER FOR THREE-DIMENSIONAL PRINTING
    Publication number: 20140044823
    Abstract: A three-dimensional printer extruder includes a thermal core, a heating element, an extrusion tip and an integrated safety system. In this configuration, the safety system is integrated into the heating element and regulates the temperature to prevent the heating element from exceeding a safe or otherwise desirable operating temperature.

  • Multi-extruder
    Patent number: 8512024
    Abstract: Multiple extrusion drive motors are nested in an overlapping configuration that permits re-use of the drive axes to support drive gears and complementary guide bearings, resulting in a compact arrangement of independently controllable extruders for multiple build materials.

  • Automated 3D build processes
    Patent number: 8287794
    Abstract: A conveyor or other transport mechanism is provided to support multiple, sequential builds from a three-dimensional fabrication machine. The conveyor may be heated/cooled, coated, or otherwise treated to assist in adhesion during a build, as well as removal of objects after a build. Each fabricated object may be automatically removed from the conveyor as the conveyor moves in order to restore a buildable surface for fabrication of additional objects.
