摘要： In an example of a method for three-dimensional (3D) printing, a build material composition is applied to form a build material layer. The build material composition includes a polyamide. The polyamide is selectively melted, based on a 3D object model, in at least a portion of the build material layer to form a molten portion including molten polyamide. An epoxy agent is selectively applied, based on the 3D object model, on the molten portion of the build material layer. The epoxy agent includes a polyfunctional epoxy, which crosslinks the molten polyamide in the molten portion.

摘要： Compositions and methods for 3D printing are described herein. In an example, a composition for 3D printing can comprise a build material comprising at least one polymer and at least one first electron donor compound; and a fusing agent comprising (i) a metal bis(dithiolene) complex, (ii) at least one surfactant, at least one second electron donor compound, or combinations thereof, (iii) a polar aprotic solvent, and (iv) water. The at least one first electron donor compound and the at least one second electron donor compound can be the same or different.

摘要： A three-dimensional printing method can include iteratively applying polymer build material as individual layers; based on a three-dimensional object model, selectively jetting an electromagnetic radiation absorber and a translucency-modulating plasticizer onto individual layers of the polymer build material; and exposing the powder bed to electromagnetic energy to selectively fuse portions of individual layers of the polymer build material together to form a three-dimensional object. The polymer build material can include from about 60 wt % to 100 wt % polymeric particles having an average particle size from about 10 ?m to about 150 ?m and a degree of crystallinity from about 2% to about 60%, to a powder bed. At the locations where the polymer build material includes jetted translucency-modulating plasticizer, the three-dimensional object can exhibit an optical transmittance from about 5% to about 80%.
