摘要： Measures for use in an additive manufacturing system. A thermal camera measures temperatures of a printbed area of the system at a first time and a second, subsequent time during additive manufacture of an object in the printbed area. A controller receives, from the thermal camera, temperature information associated with the measured temperatures at the first time and the second time and processes the received temperature information to determine a first position of a moving part of the system at the first time and a second position of the moving part at the second time. In response to the processing indicating that the moving part has not moved by a sufficient amount between the first time and the second time, the controller determines that the moving part is operating abnormally.

摘要： In one embodiment, an apparatus that removably connects to a first printer is validated, the validating including comparing first data stored within the apparatus to second data stored within the first printer. A first feature is enabled within the first printer utilizing third data stored within the apparatus. The apparatus is restricted such that the apparatus is no longer operable to enable the first feature within a printer other than the first printer.

摘要： In some examples, octree serialization can include non-transitory machine-readable medium storing instructions, the instructions executable by a processing resource to evaluate two or more nodes sequentially in an octree structure until a leaf node is reached, wherein the two or more nodes include at least one non-leaf node, and generate a serialized octree document based on a respective node identifier in a header associated with each node of the two or more nodes.

摘要： A heater may be to heat build material during a three-dimensional print job. A sensor may be to measure a temperature distribution of the build material. A processor may be to obtain first temperature data representing a first temperature distribution of build material associated with normal functioning of the heater. The processor may be to obtain second temperature data representing a second temperature distribution of the build material to be measured by the temperature sensor during the three-dimensional print job. The processor may be to compare the first temperature distribution to the second temperature distribution. The processor may be to determine whether the heater is malfunctioning based on the comparison.

摘要： An example technique for creating a voxel representation of a three dimensional (3-D) object can include obtaining a shape specification of a 3-D object and a number of 3-D objectives. The example technique for creating a voxel representation of the 3-D object can also include creating a voxel representation of the 3-D object by assigning a material type from a number of material types to each voxel of the voxel representation that defines the 3-D object. The example technique creating a voxel representation of a 3-D object can also include evaluating the voxel representation to determine whether the number of objectives are met.

摘要： A method is described in which a 3D printing file is processed, the 3D printing file having a header and including a plurality of compressed files. The method comprises reading a content of the header of the 3D printing file, identifying, based on the header content, a relation file among the plurality of compressed files, identifying, based on the relation file, a main 3D model file among the plurality of compressed files. Further the method comprises creating, by uncompressing the main 3D model file, a data stream, and analyzing, with a parser, the data stream, thereby directly processing the main 3D model file when being uncompressed.

摘要： An example technique for generating slice data from a voxel representation can include obtaining a shape specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include obtaining a material specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include merging the shape specification and the material specification to create a voxel representation of the 3-D object, wherein each voxel in the voxel representation includes a plurality of data types. The example technique for generating slice data from a voxel representation can also include generating slice data from the voxel representation, wherein the slice data provides a higher resolution than that provided by the voxel representation using the plurality of data types.
