Abstract: A grazing light system for detecting three-dimensional (3D) Additive Manufacturing Device (3D) part lift and drag may include a grazing light directed along an x, y plane of a build region to illuminate the surface of the build region, an image capture device to capture an image of the build region as illuminated by the grazing light, and an image analysis module to detect protrusions of the part along the x, y plane based on variations of luminance information within data representing the image.

Abstract: A system for presenting a soft-proof of a three-dimensional (3D) printed part may include a processor, and a memory device communicatively coupled to the processor. The system may also include a communication link to support communication with a 3D printing device, and computer usable program code to, when executed by the processor, retrieve data from the 3D printing device defining at least one capability of the 3D printing device that affects an appearance of a part when printed. The system may also include an application programming interface (API) to provide data defining generation of a soft-proof of the part based on the at least one capability of the 3D printing device, the soft-proof of the part depicting characteristics of the part as the part appears as printed.

Abstract: In one example in accordance with the present disclosure a three-dimensional illumination chart is described. The chart includes a substrate divided into a number of portions. Each portion includes a raised relief pattern disposed thereon having a relief angle relative to a reference line. Each relief angle of the raised relief patterns of the number of portions is different from other relief angles of other raised relief patterns of other of the number of portions.

Abstract: An example system includes an object and a support frame supporting the object. The support frame constrains movement of the object relative to the support frame, and the support frame includes at least one of a cage or a shackle to non-rigidly constrain movement of at least a part of the object.

Abstract: 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 μm to about 150 μm 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%.

Abstract: An example non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to generate a first surface based on an edge of a three-dimensional (3D) model. The first surface includes values indicating no displacement at locations of the first surface corresponding to the edge of the 3D model. The instructions, when executed by the processor, cause the processor to merge the first surface with a second surface to produce a third surface. The third surface includes values indicating no displacement at locations of the third surface corresponding to the edge of the 3D model.

Abstract: In an example, a method includes receiving, at a processor, a plurality of property parameter sets representing attainable property combinations in additive manufacturing and being associated with print material description. A constraint of a first property of the property parameter sets may also be received and a hull of a property mapping resource for use in determining additive manufacturing instructions for generating an object in which the first property meets the received constraint may be determined.

Abstract: 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.

Abstract: In one implementation, a method for generation of a soft-proof file is described. A ticket template and a job definition are associated with input contents. Print-ready data is caused to be generated based on the input content, the job definition, and the ticket template. A soft-proof file is caused to be generated based on the print-ready data, the ticket template, and the job definition.
