HP and Legor Group Collaborating on Precious-Metals Development for HP Metal Jet AM MachineApril 1, 2022
HP Inc. and Legor Group SPA announced a strategic collaboration for the development of innovative precious-metal materials for HP’s Metal Jet system. Legor, a developer and producer of metal alloys, powders and plating solutions, is the first to produce specialty precious-metal materials for the jewelry and fashion accessories markets designed to work with HP’s 3D metal binder jet platform.
The collaboration initially will focus on enabling the production of functional stainless-steel accessories for the jewelry and fashion markets. In parallel, the companies will implement an R&D program to parameterize and characterize bronze and silver powders, and, eventually, gold powders, the core material in the precious sector.
“Producing metal powders and 3D metal objects is part of our DNA and we always have been collaborating with customers in the jewelry and fashion-accessories world,” says Massimo Poliero, president and CEO of Legor Group SPA. “The digital capabilities of HP Metal Jet provides an alternative method to classic investment casting, which requires the combustion of waxes or resins and the use of gypsum as casting material, containing free breathable silica. It is our way to promote more robust and intentional sustainability into production processes.”
HP and Legor will work to optimize printing and sintering parameters for these new materials as well as surface-finish results. Research will take place in the new Legor 3DMetalHub in Bressanvido, Italy, a center of excellence focused on accelerating additive manufacturing (AM) for the luxury industry.
