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 an example, a method includes receiving, at a processor, a first matrix comprising a set of print coverage vectors, each print coverage vector specifying print materials for object generation using additive manufacturing and a second matrix comprising a corresponding set of properties for objects generated using the print coverage vectors. The method may further include determining, by the processor, a solution to an objective function relating the first and second matrices.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a light table, a camera, and a processor communicatively coupled to the light table and the camera. The light table is to emit light through an object on the light table. The camera is to capture an image of the light table. The processor is to receive an image of the light table without the object, receive an image of the light table with the object, and calculate a transmission value for each pixel of the object in the image of the light table with the object, wherein a mechanical property of the object is to be determined based on the transmission value of the object.

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: In an example, a processing apparatus includes an interface to receive data representing a three-dimensional object. The data includes an object description comprising object property data. The processing apparatus comprises a mapping module to map the object description to an object generation description which includes at least one print material instruction associated with a predetermined combination of print materials from a set of print materials. The mapping module includes a plurality of mapping resources and each mapping resource associates combinations of print materials from the set of print materials with values of at least one object property. At least one object property of one mapping resource is different to at least one object property of another mapping resource. The processing apparatus also includes a selection module to select, for at least part of the object, one of the plurality of mapping resources to carry out mapping of the object description.
