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.","lang":"eng"}],"date_published":"2021-12-01T00:00:00Z","publication_status":"published","issue":"6","year":"2021","intvolume":"        40","volume":40,"ddc":["000"],"project":[{"call_identifier":"H2020","grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"file_date_updated":"2021-10-27T07:08:07Z","isi":1,"acknowledgement":"The authors thank Marco Callieri for all his precious help with the resin casts.
