摘要： A system (100) is disclosed for three-dimensional printing of multi- directional woven components with hierarchical z-axis reinforcements using p re-impregnated FRP materials. The exemplary 3D printing system includes a primary extrusion nozzle system (160) and a secondary extrusion needle system (170) supported by a multi-axis truss (150). The primary extrusion nozzle system is comprised of at least two sub-extruders and rotation mechanisms (130, 330) for controllably rotating the extrusion nozzle and rotating the two-sub extruders. The extrusion nozzle assembly and the two sub-extruders can be controllably and independently rotated to extrude a braided yarn with a precise fiber-spacing. Additionally, a separate extrusion needle is provided for vertical interpenetration of the needle into the braided workpiece such that material can be extruded at precise depth through side-facing needle openings thereby providing z-axis reinforcement to the workpiece.

摘要： The present disclosure describes kits and compositions for threedimensional printing, systems for three-dimensional printing, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing comprises: a fusing agent comprising water and a radiation absorber, wherein the radiation absorber absorbs radiation energy and converts the radiation energy to heat; and a pore-promoting agent comprising water and a water-soluble pore-promoting compound, wherein the porepromoting compound chemically reacts at an elevated temperature to generate a gas, and wherein the water-soluble pore-promoting compound is selected from the group consisting of sodium bicarbonate, potassium bicarbonate, and combinations thereof.
