NAOJ is performing R&D studies related to additive manufacturing (AM) technologies based on metal 3D printing. This technology is evolving day by day in the world, both instruments and methods, and is used for diverse industries, e.g., aerospace, medical, automotive, ISS. Benefits of AM are rapid prototyping, design optimization with topology methods, cost and lead time reductions. We have...
