PureSinter Furnace Combines De-Binding and Sintering for Metal Parts Into One Machine

For high-purity, one-run de-binding and sintering of powder metal parts, PureSinter Furnace eliminates the challenges of hydrocarbons and other waste contamination with a new, patent-pending approach. Its hot walls prevent contamination buildup and provide an airtight processing environment that lets waste exit efficiently every time for high-quality sintered parts.

The furnace is compatible with powder metal parts 3D printed with additive manufacturing, such as Bound Metal Deposition (BMD) and Binder Jetting (BJT) processes, as well as traditional Metal Injection Molding (MIM) or Press and Sinter (PM) manufacturing methods. It's also compatible with all of DM's metal printer platforms and binders, and the system is currently validated with 14 metal powder and DM binder combinations, including stainless steels, tool steels, superalloys, and reactives. Additional material validations are in process.

PureSinter can reach a maximum temperature of 2,588°F (1,420°C) and is qualified for a variety of processing gasses, including argon, nitrogen, forming gas, and air. The system also features a total of 17 fans and a pop-out ceiling vent for active, rapid, and consistent cooling as well as fast turnaround times. Importantly, PureSinter does not require cold walls with water-cooling features.

With an oxygen-tight retort seal and an efficient cooling system, the electrical requirements are 200 to 220V, 40A; 380 to 415V, 20A, 3ph, 50/60hZ. With a maximum power draw of 15.2 kW, PureSinter has a holding steady state power draw of approximately 7 kW at 2,588°F (1,420°C).

PureSinter also modernizes the experience of operating a furnace, with a vertical furnace design that offers an efficient footprint, an automated thermal hood lift, touchscreen controls, and unparalleled visibility inside the retort.
