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: A three-dimensional geometry is received, and sliced into layers. A first anisotropic fill tool path for controlling a three dimensional printer to deposit a substantially anisotropic fill material is generated defining at least part of an interior of a first layer. A second anisotropic fill tool path for controlling a three dimensional printer to deposit the substantially anisotropic fill material defines at least part of an interior of a second layer. A generated isotropic fill material tool path defines at least part of a perimeter and at least part of an interior of a third layer intervening between the first and second layers.

Abstract: Combined continuous/random fiber reinforced composite filament including a plurality of axial fiber strands extending substantially continuously within a matrix material of the fiber reinforced composite filament as well as a multiplicity of short chopped fiber rods extending at least in part randomly within the same matrix material is 3D printed via a deposition head including a conduit continuously transitioning to a substantially rounded outlet tipped with an ironing lip, which is driven to flatten the fiber reinforced composite filament against previously deposited portions of the part, as the matrix material and included therein a first proportion of the short chopped fiber rods are is flowed interstitially among the axial fiber strands spread by the ironing lip. A second proportion of the short chopped fiber rods is forced against previously deposited portions of the part.

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.
