Abstract: An apparatus, system, and method is provided for predicting 3D shape deformation in additive manufacturing. A convolution learning framework for shape deviation modeling provides joint learning for a wide class of 3D shapes including both spherical and polyhedral shapes. A 3D cookie-cutter function can effectively capture the unique pattern of the shape deformation for polyhedral shapes. Since 3D freeform shapes can be approximated as a combination of spherical and polyhedral patches, the extended convolution learning framework builds a foundation for modeling and predicting the quality of 3D freeform shapes. By changing the kernel function and considering new distance measures for points from different shapes, the spatial correlations among different shapes can be correctly incorporated. The predicted deformation may be used to offset the machine instructions to an additive manufacturing machine to ameliorate deformation.
