摘要： An example system includes an identification engine to determine production data associated with a three-dimensionally printed object. The system also includes an alignment engine to determine a placement of the three-dimensionally printed object relative to a display device. The system includes a rendering engine to generate an image including a visual representation of the production data. The rendering engine is to position the visual representation of the production data so that representations of data points in the production data will overlay corresponding portions of the three-dimensionally printed object upon displaying by the display device.

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.
