A rigorous research lens on aerospace additive manufacturing (AM) must dig into technologies, breakthroughs, industry players, and white spaces. Using the MRFR report as a backbone, here’s a research-oriented exploration.

Core Technologies & R&D Directions

The aerospace AM domain is grounded in several key technologies: laser sintering, 3D printing, electron beam melting (EBM), fused deposition modeling (FDM), and stereolithography. Each has different material compatibilities and precision/throughput tradeoffs.

• Metal AM (e.g. EBM, laser sintering): Often a focal R&D area given the demand for high-temperature, high-strength parts (e.g. engine components).

• Polymeric/FDM processes: Useful for non-structural, interior, or ducting parts where mechanical loading is lower.
