Abstract: A reinforced molding is formed having an internal continuous fiber reinforcement preform embedded therein. Continuous reinforcing fiber is deposited in a reinforcement volume to form a continuous fiber reinforcement preform, and the reinforcement preform is then located within a mold of a molding apparatus. The mold is loaded with flowable and substantially isotropic molding material, e.g., by injection with heated and/or pressurized resin. The molding material is hardened (by curing or cooling or the like) to overmold the continuous fiber reinforcement preform. The resulting reinforced molding surrounds the internal continuous fiber reinforcement preform with a hardened substantially isotropic molding material.

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: A three dimensional printer incorporates a kinematic coupling between the build platform and movable stage which holds the build platform, of three curved protrusions attached to one of the build platform or the movable stage and six locating features formed in receivers of the other. At least two flexures differentially change a Z position of each of two of the curved protrusions. 3D printing is paused at a preset level of completion, and the build platform may be removed for external operations. A print resume circuit resumes printing of additional printed layers at the previous position in response to a return detection circuit that responds to an input (e.g., a touch screen confirmation).

Abstract: In a method for additive manufacturing, a multi-strand core reinforced filament including a flowable matrix material and substantially continuous reinforcing strands extending in a direction parallel to a length of the filament is supplied. A first consolidated composite swath of a height less than ½ the width of the filament is deposited in a first reinforcement formation including at least one straight path and at least one curved path against a deposition surface, and a second consolidated composite swath of a height less than ½ the width of the filament is deposited in a second reinforcement formation against the first consolidated composite swath. Each deposition flows the matrix material and applies an ironing force to spread the reinforcing strands within the filament against the underlying surface and/or previously deposited swath.
