Abstract Scope |
The NASA Tech Standard 6030 is created with the understanding that the metallic AM parts are a unique metallurgical product form. While there are similarities to other processes, the AM product is produced in a fashion that has no true precedent. It still lacks the benefit of many years of incremental refinement, which typically provides the experiential and scientific foundation. For this reason, undiscovered failure modes remain in the metallic AM process. NASA's standard is supposed to provide the implementation approach that is heavily rooted in metallurgical understanding and respecting the evolving AM process. There are a lot of questions remain in qualification of critical spaceflight AM parts. These questions lead to considering the use of “material engineering equivalence”. The presentation will cover how it can be used to evaluate the quality of AM materials that acknowledges the range of characteristics that must be assured to meet all its expectations. |
