Abstract: A method of imposing quality requirements on a 3D model including support structures to be built by an additive manufacturing apparatus including: defining the surface geometry and the orientation of the 3D model with respect to the platform, the surface geometry includes surface segments. The method further includes attributing a degree of quality (L;H) to the surface segments respectively against post-processing for the subsequent removal of the support structures calculating, based on the defined orientation, the surface geometry and the degree of quality L;H) attributed; and adding the support structure to the 3D model based on the calculated positions and the degree of quality (L;H) attributed.

Abstract: An intelligent restoration proposal including using an input resource to segment a 3D jaw model to obtain a segmented missing or unhealthy teeth and omitting the segmented missing or unhealthy teeth from the 3D jaw model to obtain a modified 3D jaw model. The modified 3D jaw model is used as input to a restoration proposal module to propose an output restoration. The restoration proposal module is operated as a machine learning engine. The restoration proposal is trained using a database that includes healthy teeth.
