Abstract Scope |
When logistics lines are long, the need for manufacturing parts using locally available resources becomes paramount. One of the significant challenges to using locally-sourced materials for critical applications is that materials of sufficient quality are often limited and vary from location to location. We present a pipeline for optimizing discovery and manufacturing in such ISRU environments. This pipeline consists of a closed-loop AI framework that integrates predictions with synthesis and characterization, generating new data and progressively improving models. Our system starts by generating new in situ constrained material structures, then predicts mechanical properties, and estimates synthesizability, targeting manufacturable structural materials. We present developments of key steps in this discovery cycle: LLMs for knowledge-base creation, physics-guided generative models, prediction synthesizability, self-supervised multi-property predictions, high-throughput directed-energy-deposition synthesis, and characterization of targeted materials. We present how our approach efficiently navigates vast materials spaces, leveraging ISRU to realize manufacturable materials on the Moon. |
