    Abstract: In additive manufacturing, composite build material filament and release material filament (each a composite of metal/ceramic powder plus binder) are dropped from respective spools to a print head. On the spools and over the drop height, the filaments are heated to a temperature that flexes the filaments but does not soften them to a breaking point, e.g., heated but below a glass transition temperature of a softener (for example, wax) of the binder. The drop height is of similar linear scale to the build plate. The materials are debound and sintered.

    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.
