摘要： The present disclosure describes three-dimensional printing kits, systems for three-dimensional printing, and methods of three-dimensional printing. In one example, a three-dimensional printing kit can include a particulate build material and a binding agent. The particulate build material can include metal particles. The binding agent can include a polyhydroxy polyol and a water-dispersible blocked polyisocyanate having multiple blocked isocyanate groups. The blocked isocyanate groups can include a blocking group bonded to the carbon atom of the blocked isocyanate group through a labile bond breakable by heating to a deblocking temperature. Breaking the labile bond can produce a released blocking group reacted with hydrogen and an isocyanate group.

摘要： A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include an outlet configured to discharge a material in a trajectory along a central axis of the outlet; a compactor disposed downstream of the outlet relative to the trajectory and configured to press the material transversely against an adjacent surface, and a cutting module located between the outlet and the compactor. The compactor and the cutting module may be configured to move together relative to the outlet.

摘要： Systems and methods for three-dimensional printing using microwave assisted deposition are disclosed herein. An example device includes a reservoir of carbonaceous nanocomposite thermoset, a microwave resonance cavity that cures the carbonaceous nanocomposite thermoset, and a sensor to measure the extrusion temperature of the resin when curing the carbonaceous nanocomposite thermoset at the point of deposition during extrusion-based 3D printing.

摘要： Various implementations include a method of printing and curing of thermoset resin. The method includes outputting a thermoset resin from an outlet of a feeder and directing a stimulus from a stimulation source toward a portion of the output thermoset resin that is downstream from the outlet of the feeder. The stimulus is configured to heat the portion of the output thermoset resin to fully cure the portion of the output thermoset resin.

摘要： An additive manufacturing system and method for including non-printable secondary materials, such as wire, metal, ceramic, electronics, optical fibers, or other materials, within a printed object. A first layer of the printed object includes a recess sized to fit a non-printable secondary material. The non-printable secondary material that aligns with an upper surface of the first layer is inserted within the recess. A heater roller flattens the upper surface, including the non-printable secondary material, to form a flat, printable surface for a second layer. The second layer is then deposited over the upper surface of the first layer and the non-printable secondary material. The non-printable secondary material can be suspended in a tray that aligns with the printed object and drops below the upper surface of the printed object to facilitate printing of the second layer.

摘要： An additive manufacturing device includes a stage configured to support a substrate. The device also includes a printhead disposed above the stage. The printhead is configured to heat a build material to a molten build material and to deposit the molten build material on the substrate in the form of droplets to fabricate an article. The device also includes a controlled heating and ablation system disposed proximal the printhead. The controlled heating and ablation system is configured to heat the substrate and ablate oxides on a surface of the substrate.
