摘要： 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.

摘要： 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.

摘要： In one example, a non-transitory processor readable medium with instructions thereon that when executed cause an additive manufacturing machine to: form a first layer of build material; form a second layer of build material over the first layer; solidify build material in the second layer to form a slice; and form a barrier that is separable from the slice to prevent a coalescing agent in the second layer penetrating build material in the first layer.
