  • Patent number: 11003166
    Abstract: In an example, a method includes receiving a first data model of an object to be generated in additive manufacturing, at a processor. Using the processor, a second data model may be determined. Determining the second data model may include generating for each of plurality of contiguous, non-overlapping sub-volumes of a volume containing the object, a sub-volume octree characterising the sub-volume and having a root node. Determining the second data model may further include generating a volume octree characterising the volume containing the object, the volume octree characterising in its lowest nodes the root nodes of the sub-volume octrees.

  • Patent number: 10853998
    Abstract: In an example, a method includes receiving, at a processor, data representing at least part of an object to be manufactured in a layer-by-layer manufacturing process. A serialised octree representation of at least part of the object may be generated from the data. In the serialised octree representation, nodes are ordered such that (i) a node representing a volume which includes a layer of the object to be generated earlier in an intended order of object generation precedes a node representing a volume which consists of layer(s) of the object to be generated subsequently; (ii) nodes representing a volume which includes a given layer of the object are ordered based on a level of the nodes within the octree representation, wherein parent nodes appear before descendent nodes; and (iii) nodes representing a volume which includes a given layer of the object and being of the same level within the octree representation are ordered according to a location encoding pattern.

  • Patent number: 10558200
    Abstract: In one example, an additive manufacturing system includes a processing system to obtain characteristic data including conditions under which a heat reservoir may be added close to a portion of the object, based on the characteristic data, add sacrificial structure data to the three-dimensional object data for a sacrificial heat reservoir structure close to a portion of the object and not connected to the object, and generate multiple slice images from the three-dimensional object data including the sacrificial structure data.

  • Publication number: 20190205483
    Abstract: In an example, a method comprises receiving machine-readable data relating to a three-dimensional object to be generated by an additive manufacturing apparatus, the machine-readable data being in a first data format. The method may further include processing, by a processor, the machine-readable data. The processing may comprise converting, by a processor, the machine-readable data from the first data format into a second data format suitable for use by the additive manufacturing apparatus to generate the three-dimensional object; and extracting metadata from the machine-readable data. The method may further include providing the processed data to an additive manufacturing apparatus for use in generating the three-dimensional object.
