Relativity Space Inc. proposes to integrate and mature its multi-dimension time series data collection capability; real-time processing elements; and closed feedback loops during a 6-month period of performance, to create real-time automatic defect detection and tagging in large-scale 3D printing applications.
3D technologies such as automatic defect detection is a key enabler for 3D printing off planet, in line with NASA's exploration goals. This, in turn, would yield benefits such as the capability for in-situ manufacturing, on-demand manufacturing from feedstock, manufacturing objects that cannot be launched from Earth, and/or the ability to design missions in novel ways to reduce cost. For example, habitat components, re-entry heat shields, or radiation shields could be manufactured on the Moon.
Across all industry (not just NASA), real-time defect detection would allow for an immediate response--such as rework to print, validation of acceptable performance with the defect, or scrapping of the part before a print is completed.
