Inside-out Design & Functionality

Desktop Metal engineers and scientists innovate again with PureSinter, a state-of-the-art vacuum furnace for sintered powder metal applications. Compared to traditional furnaces, its design was turned inside out by enabling heat to work as a purifier and preventing contaminants like oxygen from penetrating the retort during sintering. 


This furnace’s vertical design includes an up-and-down thermal hood. It contains insulation and 12 standard resistive heating elements and supports a silicon carbide (SiC) Vacuum Retort dome.

Save Costs & Energy

Desktop Metal eliminated expensive water-cooled walls; therefore, there is no need for a chiller, and it does not require high inert gas flow or a recirculating blower. PureSinter leverages the extremely high thermal conductivity of Silicon Carbide for a rapid, active, and efficient air-cooling system.

Unlike traditional furnaces, with PureSinter, the cooling happens outside of the Vacuum Retort, which means the high-flow cooling gas is simply air and does not interact with the sintering run or the parts themselves. The electrical requirements are 200-220 V, 40A, 3ph, 50/60hZ or 380-415V, 20A, 3ph, 50/60hZ.

Safety and Easy Maintenance

The engineering behind PureSinter prioritizes safety, easy maintenance, and lower energy costs. Traditional furnaces often have many joints and valves, creating unsafe leak points. PureSinter is designed with a high-purity seal to prevent any leakage or contamination of the metal powders or binding agents.

Traditional furnaces require more than 30 gallons per minute (GPM) of water and closed-loop spot coolers or chillers, which results in high operation costs. In contrast, PureSinter has a rapid air-cooling system that reduces operating and energy costs. Additionally, for easy maintenance, the furnace hood provides full visibility inside the furnace when lifted from either the front or back.

LiveSinter™ | Simple & Intuitive Software

Avoid Part Warping and Meet Dimensional Tolerances

Live Sinter is Desktop Metal’s simulation software that predicts and corrects warpage or cracking during sintering. It comes with PureSinter, which helps users create design files for geometries suitable for pressing, molding, or 3D printing and sintering to perfection. Moreover, this easy-to-use multiphysics simulation software foresees part behaviour during sintering and automatically compensates for distortion and other effects.

User-Friendly Touchscreen

The modern and intuitive touchscreen guides users through operation and maintenance and provides access to Desktop Metal’s pre-programmed furnace parameters, materials, and options for customizing sintering programs. Control panel buttons, such as lifting or lowering the furnace hood, are also operated through this touchscreen. Unlike traditional furnaces, lifting the hood provides full visibility into the furnace from the front or the back. For safety purposes, the opening and closing operation is performed with the touch of two hand control buttons.

Validated Metal Powders

PureSinter is suitable for many sintered powder metal applications within many industries. It can process metals and binders, such as Stainless Steel 17-4 PH, 316L, Cobalt-Chrome, Nickel-Alloys, H13 and D2 Tool Steels, and many more.

TiTested™ for purity

It is well known that reactive materials such as Titanium usually require expensive vacuum pumps, gas purifiers, and burnout cycles. PureSinter overcomes this challenge by sintering titanium at 98% density with properties that surpass ASTM F2885 standards for HIPed (hot isostatically pressed) PM Ti6Al4V material.
