【 摘 要 】

This paper offers a NASA perspective on guidance for fracture control and structural certification of "fracture critical" additive manufactured spacecraft structures. Results of a recent industry survey on the need for maturing NASA guidance for AM certification are presented for the first time. The survey results are placed in the context of a description of what NASA standards in this area already exist, where the gaps are, and what work to address the gaps is underway.
