    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: 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 locations of the part where the one or more supports are needed. The methods include depositing a first layer of the one or more supports at a first spacing. The methods further include depositing a second layer of the one or more supports at the first spacing. The methods additionally include repeating the deposition of additional layers of the one or more supports. The methods include printing the part onto the one or more supports.

    Abstract: Metal composites, tooling and methods of additively manufacturing these are disclosed. Metal objects and structures as provided herein are additively manufactured from metal having an infill pattern infiltrated with a metal powder. Also provided herein are methods of forming such objects and structures. Methods include additively manufacturing a metal structure having an interior printed using an infill. Steps can further include infiltrating the printed infill of the structure with a powder metal thereby forming a composite.
