Studio System™ Office-friendly metal 3D printing Desktop Metal STUDIO SYSTEM + Printer specifications The printer was designed from the ground-up for simple installation and use. Its process is similar to the safest, most widely used 3D printing process—Fused Filament Fabrication (FFF). Unlike laser-based systems that selectively melt metal powder, the Studio System™ printer extrudes bound metal rods, eliminating the safety requirements associated with metal 3D printing and enabling new features like closed-cell infill for lightweight strength. New features introduced with Studio System+ include high-resolution printing and an in-chamber camera for live viewing of the part as it prints.
