Welcome page


The ENIT Production Engineering Laboratory (LGP, EA 1905), which is multi-disciplinary, have a Mutualized Structure Research («SMR», Financed by Occitanie  Region and Europe) with companies covering the entire value chain of metal additive manufacturing on powder bed (3D machines builders, powder making, designers, 3D printers companies, end-users). This technology transfer structure is open to companies of all sizes to support their innovation processes in the field of additive / 3D  metal manufacturing.
