Abstract: Apparatuses, systems, and methods for determining a position of a nozzle of a 3D printer are described. In certain implementations, a method for determining a position of a nozzle of a 3D printer is provided. The method includes moving a nozzle assembly relative to a test feature of a calibration object such that a nozzle tip contacts the test feature for a plurality of times. The nozzle assembly includes the nozzle that has the nozzle tip. The method also includes reading positions of the nozzle when the nozzle tip contacts the test feature. The method further includes determining a relative position of an end point of the nozzle relative to a reference point.

Abstract: A reinforced molding is formed having an internal continuous fiber reinforcement preform embedded therein. Continuous reinforcing fiber is deposited in a reinforcement volume to form a continuous fiber reinforcement preform, and the reinforcement preform is then located within a mold of a molding apparatus. The mold is loaded with flowable and substantially isotropic molding material, e.g., by injection with heated and/or pressurized resin. The molding material is hardened (by curing or cooling or the like) to overmold the continuous fiber reinforcement preform. The resulting reinforced molding surrounds the internal continuous fiber reinforcement preform with a hardened substantially isotropic molding material.

Abstract: In molten metal jetting, where droplets of metal are jetted to 3D print a part, each layer may be traversed each successive layer with a normalizing grinding wheel or other leveling device such as a layer to level each successive layer, and/or the melt reservoir or printing chamber may be filled with an anoxic gas mix to prevent oxidation.

Abstract: Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Abstract: A footwear insole shape is generated by supplying a core reinforced filament having a matrix material impregnating reinforcing strands aligned along the filament, as well as a fill material separately from the core reinforced filament and depositing at least one shell of fill material within an insole shape upon a print bed. The core reinforced filament is deposited to fuse to the fill material within a first reinforcing region formed with respect to the insole shape. A cutter upstream of the nozzle tip cuts the core reinforced filament, and a remainder of the core reinforced filament is deposited to complete the first reinforcing region. A nozzle tip applies pressure to continuously compact the core reinforced filament toward the insole shape as the core reinforced filament is fused to the fill material.
