Abstract: According to an example, a computing apparatus may include a processing device and a machine readable storage medium on which is stored instructions that when executed by the processing device, cause the processing device to access, from a sensing device, information pertaining to formation of a part of a 3D object in a layer of build materials upon which fusing agent droplets have been or are to be selectively deposited. The instructions may also cause the processing device to predict, based upon the accessed information, a quality of the part and output an indication of the predicted quality of the part.

Abstract: According to one example, there is provided a system for generating a three-dimensional object. The system comprises a carriage to move bi-directionally along a first axis relative to a support platform. The carriage is to receive, or have installed thereon, a plurality of modules each to perform an operation from a set of operations to generate a layer of a three-dimensional object. The system further comprises a controller to cause relative movement between the carriage and the support platform along the first axis, and to control, during the relative movement, operation of the modules to perform the set of operations in a predefined order.

Abstract: Certain described examples relate to the generation of data for use in producing a three-dimensional object. Certain examples utilize lattice indexes to define a lattice associated with a particular portion of the three dimensional object. The lattice index may be used in a matrix generation operation that compares index values with threshold values to generate a three-dimensional lattice matrix. The three-dimensional lattice matrix is useable to instruct a structure of the three-dimensional object.

Abstract: According to one aspect there is provided apparatus for generating a three-dimensional object. The apparatus comprises a first agent distributor to selectively deliver a coalescing agent onto portions of a layer of build material, a second agent distributor to selectively deliver a coalescence modifier agent onto portions of a layer of build material, and a controller to control the agent distributors to selectively deliver each of the agents onto a layer of build material in respective patterns derived from data representing a slice of a three-dimensional object to be generated, so that when energy is applied to the layer the build material coalesces and solidifies to form a slice of the three-dimensional object in accordance the patterns.

Abstract: An additive manufacturing system is described. The system includes a working area with a moveable platform, a supply mechanism to supply a build material to the working area, a radiation source to apply energy to the working area during construction of an object, so as to fuse at least a portion of the build material, a platform advance sensor to determine a displacement of the platform in at least a direction perpendicular to the plane of the platform, and a radiation source controller to adjust the energy applied by the radiation source based on the displacement measured by the platform advance sensor.
