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 ?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%.

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: Examples analyze three-dimensional printing specifications associated with a three-dimensional printing device to determine test angles for a test object and test surfaces corresponding to the test angles for the test object. Examples generate the test object for color calibration for the three-dimensional printing device based at least in part on the test angles and test surfaces that are configured with at least one test color.

Abstract: A device includes a material dispenser and a fluid dispenser. The material dispenser is to dispense a build material layer-by-layer, to at least partially additively form a first 3D object. The fluid dispenser is to dispense at least one fluid agent at selectable exterior voxel locations of the respective layers to at least partially define an external surface of the first 3D object as a first color to represent a first non-color material property of at least a first portion of the first 3D object. The selection of the first color is independent of characteristics of the first non-color material property.

Abstract: An apparatus receives a first image of an object captured under a first light measurement condition and receives a second image of the object captured under a second light measurement condition. The apparatus determines a first transmission value of the object based on the first image, determines a second transmission value of the object based on the second image, and determines, based on a difference between the first transmission value and the second transmission value, a light scattering property of the object.

Abstract: According to an example, an apparatus may include a processor and a memory on which is stored instructions that are to cause the processor to identify features for a three-dimensional (3D) indicator object to be fabricated by a 3D fabricating device, in which the identified features define a shape and a pattern of colors for the 3D indicator object. The instructions may also cause the processor to instruct the 3D fabricating device to fabricate the 3D indicator object to have the identified features, in which the 3D indicator object has a shape having a plurality of surfaces on which a plurality of colors are arranged in a certain pattern as defined by the identified features, and in which each of the plurality of surfaces has the same certain pattern of the plurality of colors and determine properties of the fabricated 3D indicator object.

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.
