Desktop Metal has expanded the capabilities of its P-1 Production System, announcing that platinum is now a customer-qualified material for binder jetting. This development, enabled by a specialized powder from Legor, marks a significant step in additive manufacturing for precious metals.

The 3D printer manufacturer Desktop Metal announced that platinum is now a customer-qualified material for its P-1 Production System, using a special powder developed by Legor.
In 2023, Legor invested in a Desktop Metal P-1 Production System, a high-speed binder jetting 3D printing system with Single Pass Jetting (SPJ) technology. This technology offers several advantages over traditional manufacturing methods and other 3D printing processes, including the rapid production of jewelry samples without molds or print supports, new design freedom for hollow, interwoven, and customized creations, and simplified processing of difficult materials like platinum.
An important aspect of Binder Jet 3D printing technology is sustainability. Fabio Di Falco emphasized that the technology represents a significant step towards more sustainable production, as it is energy-efficient and reduces the amount of material used. Unused metal powder can be reused, reducing the need for new raw materials and the risks associated with metal mining.
At RAPID + TCT, North America’s largest additive manufacturing and industrial 3D printing trade fair, to be held from June 25 to 27 in Los Angeles, Desktop Metal will present platinum jewelry designs. These will include a classic wedding ring, a gemstone ring, and a filigree leaf earring, all 3D printed by Legor.
