Desktop Metal has unveiled the PureSinter Furnace, designed for high-purity debinding and sintering of powder metal parts in a single run. This new furnace is compatible with various additive manufacturing processes like Bound Metal Deposition (BMD) and Binder Jetting (BJT), as well as traditional manufacturing methods such as metal injection molding (MIM) or press and sinter (PM).
According to Ric Fulop, the founder and CEO of Desktop Metal, the PureSinter Furnace represents a significant innovation in furnace design. The company has spent over 5 years developing this new furnace, which features hot walls to prevent contamination buildup and an airtight processing environment for efficient waste exit and high purity levels.
The PureSinter Furnace has undergone rigorous testing and has shown minimal contamination even after hundreds of runs. It can sinter a wide range of materials, including titanium, with confidence. The furnace can reach a maximum temperature of 1,420°C and is compatible with various processing gases like argon, nitrogen, forming gas, and air.
One of the key features of the PureSinter Furnace is its rapid cooling system, which includes 17 fans and a pop-out ceiling vent for consistent cooling and fast turnaround times. Importantly, the furnace does not require expensive water-cooling features, making it a cost-effective and efficient solution for manufacturers.
The PureSinter Furnace is currently validated with 14 metal powder and binder combinations, including stainless steels, tool steels, superalloys, and reactives. Additional material validations are ongoing, further expanding the furnace’s capabilities.
In conclusion, the introduction of the PureSinter Furnace by Desktop Metal marks a significant advancement in sinter-based additive manufacturing and traditional furnace industry. The innovative design and features of the PureSinter Furnace are set to revolutionize the way manufacturers produce high-purity powder metal parts.
