    Abstract: Examples of methods for monitoring additive manufacturing by an electronic device are described herein. In some examples, a predicted thermal image is calculated for a layer. In some examples, a captured thermal image is obtained for the layer. In some examples, a risk score is calculated for the layer based on the predicted thermal image and the captured thermal image. In some examples, a mitigation operation is performed in response to determining that the risk score is outside of a threshold range.

    Abstract: A method of packing a three-dimensional (3D) build bed includes, with a shape-based packing module, and for a number of iterations, selecting two parts from a plurality of parts within a parts list, and minimizing a volume of a composite bounding box that encloses both parts. The method may also include determining abounding box reduction ratio (BBRR) by computing the volume of the composite bounding box divided by a sum of the volumes of a first bounding box enclosing a first part of the two parts and a second bonding box enclosing a second part of the two parts, and, in response to a determination that the BBRR is lower than a threshold value, combining the two parts to form a composite part.

    Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises object property data indicative of properties of the three-dimensional object. Layers within the three-dimensional object to be printed are identified. The obtained data is processed by comparing object property data associated with an identified layer to object property data associated with a reference layer selected from the identified layers. Where a difference in object property data associated with an identified layer and object property data associated with a reference layer is determined, the determined difference is stored.

    Abstract: 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.
