Design for additive manufacturing : Methods and tools for part definition
Zodiac Company develop and make aeronautical mechanism. Their main preoccupation is to make light part to reduce oil consumption. But this weight reduction don’t have any consequences on fly safety. The functional requirement: part volume, cinematic mechanism, strength resistance must be respected. Additive manufacturing allowed to more liberty on part shape. This allowed shape which is not realizable with conventional process. Thanks to the topological optimization, the material was reorganized in possible: load case, process… The part weight was reduce and keep mechanical properties to respect load cases. This can be introduce original design. So, additive manufacturing has a huge potential which are essential for companies to investigate.
Some works realized in g-scop laboratories led to identify different process for additive manufacturing, capacity and constraint bind to their utilization. The implementation on EBM process allowed to bring out and to characterize certain manufacturing phenomena and to do some recommendations or rules to anticipate them during the design phase; to suggest a method to integrate process characteristics during the design phase. A lot of works were initiated at Grenoble: on materials, on process characteristics, on method and tools to go with design methodology for this type of process. Competences are available and developed on design for additive manufacturing.
