    摘要: A system for creating a feedstock line for additive manufacturing of an object comprises a prepreg-tow supply, a prepreg-tow separator, an optical-direction-modifier supply, a combiner, and at least one heater. The prepreg-tow supply dispenses a precursor prepreg tow, comprising elongate filaments and resin. The prepreg-tow separator separates the precursor prepreg tow into individual elongate filaments at least partially covered with the resin. The optical-direction-modifier supply dispenses optical direction modifiers to the elongate filaments. When electromagnetic radiation strikes the outer surface of the optical direction modifiers, at least a portion of the electromagnetic radiation departs the outer surface at an angle. The combiner combines the elongate filaments and the optical direction modifiers into a derivative prepreg tow. At least the one heater heats the resin to cause wet-out of the optical direction modifiers and the elongate filaments in the derivative prepreg tow by the resin.

    摘要: A system for use in producing a nanotube mesh structure is provided. The system includes a first nanotube collection apparatus including a first substrate configured to collect a plurality of nanotubes substantially aligned in a first orientation on an attachment surface thereof, and a second nanotube collection apparatus including a second substrate configured to collect a plurality of nanotubes substantially aligned in a second orientation on an attachment surface thereof. The first and second nanotube collection apparatuses are configured to combine the pluralities of nanotubes at an interface. The system also includes a first energy source configured to direct energy towards the interface between the pluralities of nanotubes, wherein the energy is configured to join the pluralities of nanotubes to form the nanotube mesh structure.

    摘要: Systems for additive manufacturing comprise a delivery guide configured to dispense a curable material to additively manufacture a part in sequential layers of the curable material, and a source of curing energy configured to direct the curing energy to a discrete region of the curable material forward of or at a location where a subsequent layer of the curable material is dispensed from the delivery guide against a preceding layer of the curable material to cure together the subsequent layer and the preceding layer. Methods of additively manufacturing comprise dispensing a subsequent layer of a curable material against a preceding layer of the curable material, and concurrently with the dispensing, directing curing energy to a discrete region of the curable material to cure together the subsequent layer and the preceding layer.
