Design for additive manufacturing is focusing on rules and methods to support new components development and redesign. In this paper, the design of a high-performance cryogenic silicon wafer holder is presented according to a design workflow able to accomplish the component redesign and optimization with and without lattice structure. The test case is a next-generation cryogenic detector for particle physics research, named BULLKID Project, applied in the field of neutrino and dark matter, and carried out by INFN (the Italian National Institute of Nuclear Physics) of Rome (Italy) with the support of Sapienza University of Rome (Italy). Starting from the design requirements that involve not only the performance but also assembly and manufacturing, a new silicon wafer holder is designed and manufactured by Laser-Powder Bed Fusion (L-PBF) with the aim of increasing the numbers of detectors per assembly. According to this development, via Computer Aided Engineering (CAE), the new design has been validated and printed. Redesign efficiency and drawbacks have been assessed with the perspective of the component lightweight also studying lattice insertion.

摘要

Design for additive manufacturing is focusing on rules and methods to support new components development and redesign. In this paper, the design of a high-performance cryogenic silicon wafer holder is presented according to a design workflow able to accomplish the component redesign and optimization with and without lattice structure. The test case is a next-generation cryogenic detector for particle physics research, named BULLKID Project, applied in the field of neutrino and dark matter, and carried out by INFN (the Italian National Institute of Nuclear Physics) of Rome (Italy) with the support of Sapienza University of Rome (Italy). Starting from the design requirements that involve not only the performance but also assembly and manufacturing, a new silicon wafer holder is designed and manufactured by Laser-Powder Bed Fusion (L-PBF) with the aim of increasing the numbers of detectors per assembly. According to this development, via Computer Aided Engineering (CAE), the new design has been validated and printed. Redesign efficiency and drawbacks have been assessed with the perspective of the component lightweight also studying lattice insertion.
