Classification: CPC B  G  Y | IPC B  G

Claim 7:
8. A method comprising:
sensing thermal maps of a three-dimensional (3D) part as the 3D part is printed on a 3D printer;
generating layer sequences including the thermal maps and the contone agent maps for each layer of the 3D part;
segmenting each layer sequence into patches to generate patch sequences;
selecting training samples from the patch sequences having temperature intensity variations within each layer or between neighboring layers;
training a neural network using the training samples to generate a model to predict thermal behavior in the 3D printer;
generating layer sequences including contone agent maps for a part to be printed on the 3D printer;
segmenting the contone agent maps for the part to be printed for each layer sequence into overlapping patches to generate patch sequences;
applying the model to each patch sequence to generate a patch level prediction for each patch sequence; and
merging the patch level prediction for each patch sequence into a build bed prediction for the part to be printed.
