    摘要： One example includes a non-transitory machine readable storage medium including voxels organized by an octree and at least one quad-tree index. The octree defines an object to be three-dimensionally printed and includes a list of nodes for each depth of the octree where each node includes nodal content representing at least one voxel. The at least one quad-tree index is to index at least one node of the octree and has a depth less than or equal to a maximum resolved depth. The at least one quad-tree index is to be accessed by computer executable instructions to retrieve nodal content from the octree to control a processor to process the object to be three-dimensionally printed.

    摘要： According to an example, a processing device may slice a 3D model along a first direction to generate a plurality of layers in parallel planes defined across a second direction and a third direction, in which each of the plurality of layers is composed of respective polygons representing portions of the 3D model. The plurality of layers may be partitioned into a plurality of stacked boxes containing the respective polygons and for each stacked box of the plurality of stacked boxes, the polygons in the stacked box may be assembled into a superset polygon and the superset polygon may be partitioned into bounding shapes. A shape profile of the 3D object may be generated using the bounding shapes.

    摘要： A controller may be to receive temperature data representing a temperature distribution of at least part of a current layer of build material that is measured by a temperature sensor. The controller may be to determine one or more weighting factors representing a degree of influence of each of one or more previous layers of the build material beneath the current layer on a property of the current layer. The controller may be to identify one or more regions in the current layer based on the one or more weighting factors and based on how the property is exhibited by each of the one or more regions. The controller may be to cause the current layer to achieve a target temperature if the temperature data in a selected region of the identified one or more regions does not match the target temperature.

    摘要翻译： 控制器可以接收表示由温度传感器测量的构建材料的当前层的至少一部分的温度分布的温度数据。 控制器可以确定一个或多个加权因子，其表示当前层下面的构建材料的一个或多个以前的层的每一个的影响程度对当前层的属性的影响程度。 控制器可以基于一个或多个加权因子并且基于如何由一个或多个区域中的每个区域呈现属性来识别当前层中的一个或多个区域。 如果所识别的一个或多个区域的选定区域中的温度数据与目标温度不匹配，则控制器可以使当前层达到目标温度。
