Kazuhiko Nishioka and Koji Kageyama, who were at Nippon Steel at the time, conceived of their own metal 3D printing technology using their microwave-based steelmaking method, which had never existed in the market before, and after conducting experiments at a campsite, they founded Sun Metalon in February 2021. Their vision is "By enabling local production and local consumption of metal parts, we dramatically expand the possibilities for human beings in space."

-Innovative metal 3d printing (ultra-fast, ultra-cheap, ultra-huge) method based on original technology and its patent.
-Founding team of top engineers with extensive experience in industry and academia, supported by a strong scientific advisory board (MIT, Oxford, The University of Tokyo)

-Effective management support, based on a wealth of experience and success in the deep tech startups.
-Support for hiring executive personnel and introduction of various expert personnel (marketing, intellectual property strategy, etc.)
