Abstract: A material deposition system for additive manufacturing including an extruder that defines a first input passage for supplying a first material, a second input passage for supplying a second material, a chamber for combining the first and second materials to form a combined deposition material, and an extrusion port for extruding the combined deposition material. The system further includes an adjustable sleeve that is movable between a first position and a second position to vary the interaction between the first material and the second material in the chamber. For example, the adjustable sleeve may be configured to separate the first and second materials in the chamber, and can vary the point at which the materials interface with each other prior to deposition based on the sleeve position. Such a system may enable a varying degree of infiltration, encapsulation, or other interaction between the first and second materials prior to deposition.

Abstract: A three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.

Abstract: A thermoplastic composite structure is produced by extruding a bead of composite material to a desired cross sectional shape. An extruder extrudes the polymer bead containing reinforcing fibers, using a low compression first extruder stage where the polymer is mixed and de-gassed, and a high compression second stage where the polymer is consolidated and extruded. The cross sectional profile of the polymer bead may be altered using a variable extruder gate.
