Legor has successfully qualified its Powmet platinum powder for use with the Desktop Metal Production System P-1, a binder jetting platform. This qualification enables the direct additive manufacturing of high-purity platinum jewelry components, bypassing traditional casting and manual finishing processes. The technical validation ensures that the powder meets the specific rheological and sintering requirements necessary for the P-1 system to produce dense, high-quality jewelry parts. This development allows manufacturers to integrate platinum into digital workflows, reducing material waste and enabling complex geometries that are otherwise unattainable through conventional fabrication methods.

This integration addresses the significant challenge of processing high-melting-point precious metals in binder jetting systems. While LPBF has been used for platinum, binder jetting offers a more scalable and cost-effective route for high-volume jewelry production by eliminating the need for support structures and minimizing post-processing labor. The jewelry sector, particularly luxury houses, is increasingly adopting additive manufacturing to shorten lead times for bespoke collections and improve material utilization. By aligning specialized powder metallurgy with established binder jetting hardware, Legor and Desktop Metal are positioning themselves to capture a larger share of the digital jewelry manufacturing market.

For jewelry manufacturers, this qualification means that platinum can now be treated as a standard material within a binder jetting production environment. Users should focus on optimizing sintering cycles to ensure the final density and surface finish meet luxury retail standards. This is a practical step toward standardizing precious metal additive manufacturing, requiring manufacturers to validate their specific sintering profiles to achieve consistent results.
