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 applying the filament from the conduit nozzle.

Abstract: In a 3D composite printer, toolpaths defining fill material shells are received, as are toolpaths defining support material shells. A 3D toolpath defining a long fiber composite material curved shell is also received. A fill material deposition head traces the toolpaths to deposit some of the fill material shells or support material shells at least in part non-parallel to a printing substrate. A long fiber deposition head traces the 3D toolpath at least in part non-parallel to the printing substrate to deposit the long fiber composite material curved, concave, ring, tube, or winding shells to enclose, surround, or envelop at least a portion of the fill or support material shells.

Abstract: Methods of printing parts, e.g., using a 3D printer, are disclosed. The methods include receiving a representation of a part to be printed. The methods include analyzing the representation along one or more of an X-Y plane, X-Z plane, and Y-Z plane to identify an aspect ratio of the part. The methods include comparing the aspect ratio to a threshold value. The methods further include determining that a support structure for the part is needed based on the comparison of the aspect ratio to the threshold value. The methods additionally include providing instructions to a 3D printer to print the part including the support structure.

Abstract: A 3D printing apparatus and method determines an optimized reinforcement strategy for improving one or more mechanical properties of a part to be printed. The optimization may include determining reinforcement parameters which yield the highest improvement in such mechanical properties. The reinforcement parameters may include one or more particular portions of the part to print using a reinforced material, a fiber orientation, a density of print material.
