Desktop Metal Introduces PureSinter™ – a High-Purity Vacuum Furnace that Delivers Premium Debind-and-Sinter Performance at an Affordable Price
- PureSinter offers one-run debinding and sintering of metal parts produced with either Additive Manufacturing or traditional manufacturing methods in a 15.8L retort
- In development for five years, this all-new furnace was designed for ease-of-use, premium performance, reliability, and low cost of acquisition and operation
- PureSinter features a revolutionary, patent-pending machine design that delivers parts-per-billion levels of purity in a high-efficiency, airtight processing environment — ensuring a clean and reliable furnace with low operating costs
- With more than 17 fans and a pop-out ceiling vent, PureSinter can cool from 1,420°C to 200°C in less than four hours without expensive water-cooled walls
- Titanium parts sintered in PureSinter demonstrate better performance results for density, tensile strength, and elongation than an all-metal retort third-party furnace with lower energy consumption and without complex setup requirements and getter materials
-
The first PureSinter Furnace has been installed at FreeFORM Technologies, a metal binder jet contract manufacturer based in
St. Marys, Pennsylvania , and the largest owner of a Super Fleetof 24 3D printers, to validate new materialsDesktop Metal - Standard shipments of the PureSinter Furnace — which is now validated with 14 metal powder and binder combinations, with more to follow — are slated to begin in Q3
-
The Desktop Metal PureSinter Furnace will make its global debut
June 25-27 inLos Angeles at Rapid + TCT, North America’s largest additive manufacturing and industrial 3D printing event

PureSinter 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.
For decades, the powder metal manufacturing industry has been challenged by sintering furnaces that are easily contaminated by hydrocarbons and other waste emitted by powdered metal parts. This contamination builds up on walls and other surfaces inside the furnace and causes undesirable chemical reactions and furnace reliability complications that have long challenged powder metal manufacturers.
“Rather than trying to simply mitigate the factors that lead to poor performance in an all-in-one debinding and sintering furnace, we have eliminated them with an innovative all-new design,” said
“We have put the PureSinter through a prolonged period of testing to rigorously verify our new design, and it has exceeded all expectations. PureSinter is an exemplary demonstration of the innovation for which

All-New Furnace Design
In development for more than five years, PureSinter reinvents furnace design from the ground up to eliminate traditional furnace challenges with an all-new, patent-pending approach. PureSinter features hot walls that prevent contamination buildup and an airtight processing environment to ensure efficient waste exit and the highest levels of purity.
PureSinter has undergone extensive testing and shows little to no contamination or buildup inside the furnace, even after hundreds of runs. Consequently, PureSinter delivers the highest quality sintered parts, on par or better than premium furnaces with higher acquisition, energy utilization, and operating costs. Even titanium can be easily sintered with a high degree of confidence without the complex preparations required with other furnaces. PureSinter is Ti-Tested™ with excellent results.
The PureSinter furnace is 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 1,420°C and is qualified for use with 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 expensive water-cooling features. As experienced furnace users know, cold walls are collection points for debinding residue and contaminants.
With an oxygen-tight retort seal, and an efficient cooling system, the PureSinter energy requirements offer a dramatic improvement over other state-of-the-art furnaces that it competes with on performance. The electrical requirements are 200-220V, 40A; 380-415V, 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 1420°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.
