摘要: A three-dimensional printing system includes a controller to instruct a fusing agent distributor to selectively apply a fusing agent to a first region of a layer of build material. The controller also determines a subset of voxels in the layer of build material to provide an opacifying agent based on an opacity value of an opacified region of an object to be generated and instructs an opacifying agent distributor to apply the opacifying agent to the determined subset of voxels.

摘要: An example of a fusing agent includes a tetraphenyldiamine-based dye, alkyldiphenyloxide disulfonate, 1-methyl-2-pyrrolidone, and a balance of water. The fusing agent excludes a strong reducing species. The fusing agent may be incorporated into a three-dimensional printing method or a three-dimensional printing system. In an example of the three-dimensional printing method, a polymeric or polymeric composite build material is applied. The fusing agent is selectively applied on at least a portion of the polymeric or polymeric composite build material. The polymeric or polymeric composite build material is exposed to electromagnetic radiation to fuse the portion of the polymeric or polymeric composite build material in contact with the fusing agent to form a layer.

摘要: To additively manufacture a 3D object, a layer of material is deposited onto a receiving surface. Droplets are selective deposited onto first portions of the layer with at least some droplets including at least a first color agent. A gas discharge illuminant selectively induces a first amount of heating in the first portions of the layer substantially greater than a second amount of heating in second portions of the layer omitting the first color agent.
