Studio System™ Office-friendly metal 3D printing Desktop Metal STUDIO SYSTEM + Furnace specifications Fully-automated and sized to fit through a doorway, the furnace delivers industrial-strength sintering in an office-friendly package. The furnace uniformly heats parts to just below their melting point to remove secondary binder, causing the metal particles to fuse together and the part to densify up to 96 to 99.8%—without residual stresses introduced in laser-based systems. New features introduced with Studio System+ include a newly designed retort box with adjustable shelving designed for batch processing.
