摘要： A method of fabricating a three dimensional object in an additive layer manufacturing process, e.g. 3D printing, wherein a three dimensional design of the three dimensional object is modelled as a plurality of three dimensional pixels or vortexes. For every pixel or vortex, at least one parameter is calculated and is used to select a setting for use when fabricating the three dimensional object. The parameter may be a speed or rate at which heat will diffuse away from the pixel or vortex, or a weighted density surrounding the pixel or vortex. The method provides higher quality fabrication of the three dimensional object.

摘要： 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.

摘要： In an example, a method includes forming, at an additive manufacturing apparatus, a first layer of build material to be processed in the generation of an object. A print agent is selectively applied onto the first layer based on a first print instruction associated with the first layer. Energy is applied to the first layer to cause fusion in a region of the first layer. The method further comprises: measuring the temperature of the first layer at a plurality of locations to form a measured temperature distribution profile; comparing the measured temperature distribution profile against a predicted temperature distribution profile to generate a difference; and correcting a temperature distribution profile of a subsequent layer of the build material following fusion of the subsequent layer based on the difference by modifying a second print instruction associated with the subsequent layer.
