Such decomposition enables the manufacturing of individual parts using two-piece reusable rigid molds. Our decomposition strategy relies on a new energy formulation that utilizes a pre-computed signal on the mesh volume representing the accessibility for a predefined set of extraction directions. Thanks to this novel formulation, our method allows for efficient optimization of a fabrication-aware partitioning of volumes in a completely\r\nautomatic way. We demonstrate the efficacy of our approach by generating valid volume partitionings for a wide range of complex objects and physically reproducing several of them."}],"isi":1,"external_id":{"isi":["000729846700077"]},"date_published":"2021-12-01T00:00:00Z","article_processing_charge":"No","citation":{"ista":"Alderighi T, Malomo L, Bickel B, Cignoni P, Pietroni N. 2021.
