    Abstract: A system and method for providing three dimensional printing production quality prediction is described herein. The system may include logic to scan a region of interest associated with a layer of a plurality of parts during printing to obtain an input for the region of interest and compute an input metric associated with the layer based on the input. In response to an initial set of print jobs, at least a portion of the plurality of parts is mechanically tested to determine at least one output. In response to a production print job, a likelihood of a part of the plurality of parts to satisfy a quality specification is predicted by inputting the input metric to at least one machine learning function comprising the at least one output, wherein the at least one machine learning function is trained during the initial set of print jobs.

    Abstract: An example system includes a kernel generation engine. The kernel generation engine is to generate a plurality of kernels based on a description of a physical state. The plurality of kernels are generated based on applying a neural network to the description of the physical state. The system includes a calculation engine to apply the plurality of kernels to the description of the physical state to produce a plurality of intermediate descriptions. The system includes a weighting engine to determine a plurality of weight maps based on the plurality of kernels. The system includes a compositing engine to apply the plurality of weight maps to the plurality of intermediate descriptions to produce weighted intermediate descriptions and to combine the weighted intermediate descriptions to produce an updated description of the physical state.

    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.
