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: In example implementations, an apparatus is provided. The apparatus includes a light table, a camera, and a processor. The light table is to hold an object. The camera is to capture images. The light table is positioned within a field of view of the camera. The processor is communicatively coupled to the camera to receive the images. The processor is to analyze the images to calculate an imaged transmission percentage at a plurality of different locations of the object based on a correlation function of the camera used to determine an amount of print agents to be dispense by a three dimensional printer to print the object.

Abstract: Color chart characterization and techniques related therewith are described herein. In an example, an image including a reproduction of a color chart may be received by a computing system. Data associated with the color chart may be received. The data is encoded in an encoding element located in a substrate including the color chart. The color chart may be automatically characterized based on the received data.

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.
