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."}],"author":[{"first_name":"Thomas","full_name":"Alderighi, Thomas","last_name":"Alderighi"},{"first_name":"Luigi","last_name":"Malomo","full_name":"Malomo, Luigi"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd","last_name":"Bickel","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd"},{"last_name":"Cignoni","full_name":"Cignoni, Paolo","first_name":"Paolo"},{"full_name":"Pietroni, Nico","last_name":"Pietroni","first_name":"Nico"}],"publisher":"Association for Computing Machinery","intvolume":"        40","main_file_link":[{"open_access":"1","url":"http://vcg.isti.cnr.it/Publications/2021/AMBCP21"}],"date_updated":"2024-02-28T12:52:48Z","publication_status":"published","has_accepted_license":"1","article_number":"272","file":[{"file_name":"rigidmolds-authorversion.pdf","content_type":"application/pdf","creator":"bbickel","file_size":107708317,"access_level":"open_access","relation":"main_file","file_id":"10185","checksum":"384ece7a9ad1026787ba9560b04336d5","date_created":"2021-10-27T07:08:07Z","date_updated":"2021-10-27T07:08:07Z"}],"file_date_updated":"2021-10-27T07:08:07Z","language":[{"iso":"eng"}],"isi":1,"ec_funded":1,"_id":"10184","day":"01","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"12"}
