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 extrusion 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 extruding the filament from the extrusion nozzle.

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: To reduce distortion in an additively manufactured part, a densification linking platform and/or supports of the same composite as the desired part may be printed below the part. After debinding, a resulting shape-retaining brown part assembly is sintered to densify together at a same rate as neighboring metal particles throughout the shape-retaining brown part assembly undergo atomic diffusion. Distortion is reduced by interconnecting portions of the shape-retaining brown part assembly, printing release layers among the portions, depositing adjacent roads of the assembly in retrograde directions, and/or providing channels to accelerate a debinding process.

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.
