ExOne Expands Collaboration with Elnik Systems and DSH Technologies to Improve Sintering Standards for Metal 3D Printing

The ExOne Company (Nasdaq: XONE), the global leader in industrial sand and metal 3D printers using binder jetting technology, is expanding its collaboration with two companies — Elnik Systems, the global leader in debind and sinter equipment, and DSH Technologies, LLC, a global leader in debind and sinter process consulting — to improve standardization of sintering for metals 3D printed with binder jetting.

ExOne’s family of metal 3D printers are capable of printing more than six qualified metal powders, including the popular stainless steels 316L, 304L and 17-4PH, into dense, solid parts. A variety of beta metals are also being fast-tracked through the Company’s strict qualification process, such as Inconel 718 and 625. To earn qualification, a metal must deliver repeatable, desirable performance in both 3D printing and sintering.

The expanded collaboration between ExOne, Elnik, and DSH will focus on improving sintering profiles for metal parts 3D printed on ExOne binder jetting systems. Standard profiles will be based on metal type, as well as part features, including size, mass and other geometric elements. The companies will also co-develop an easy-to-use interface that will automatically load, or allow a user to select, sintering profiles.

"ExOne metal 3D printers already deliver industry-leading density and repeatability, and now we’re working to ensure that the final sintering step is as easy as possible for our customers — a seamless end-to-end process that delivers a quality result,” said John Hartner, ExOne CEO. "We’re proud to work with Elnik Systems, the leaders in debind and sinter equipment and services, on enhancing the quality of our solutions.”

"We are honored to be collaborating with the experienced ExOne team on technology enhancements for metal binder jetting technology,” said Stefan Joens, Elnik President/DSH Vice President. "Elnik’s introduction of all metal partial pressure furnaces has transformed the processing capabilities of the metal injection molding (MIM) industry, and we are excited to bring this technology to the metal AM industry. DSH Technologies has been providing real world solutions focused on customers-specific issues for 20 years.”

Understanding Binder Jetting

Binder jetting is a mature 3D printing process that uses a digital file to quickly inkjet a binder into a bed of powder particles — metal, sand or ceramic — creating a solid part one layer at a time. When printing metals, the final part must be sintered in order to fuse the particles together into a solid object.

Compared to other manufacturing methods, binder jetting is a fast and low-waste method of making precision metal parts and products. What’s more, it offers new design freedoms not previously possible.

While sintering metal powders is a common manufacturing process, and ExOne customers successfully sinter parts today, the design freedom offered by 3D printing is creating new challenges in sintering green metal parts that deliver predictable dimensional tolerances and meet other requirements. The process often involves some trial and error with sacrificial parts. The new collaboration with Elnik aims to standardize and simplify this end-to-end process.

At Formnext 2019, both ExOne and Elnik will showcase metal parts that were binder jet 3D printed on ExOne systems and sintered in an Elnik furnace. ExOne and Elnik are both located in Hall 12.0. ExOne is at Booth C21, while Elnik is at Booth B69.

About ExOne

ExOne is a global provider of 3D printing machines, 3D printed products, materials and services to industrial customers. ExOne's business primarily consists of manufacturing and selling 3D printing machines and printing products to specification for its customers using its installed base of 3D printing machines. ExOne’s machines serve direct and indirect applications. Direct printing produces a component; indirect printing makes a tool to produce a component. ExOne offers pre-production collaboration and print products for customers through its network of ExOne Adoption Centers ("EACs”). ExOne also supplies the associated materials, including consumables and replacement parts, and other services, including training and technical support that is necessary for purchasers of its 3D printing machines to print products. The Company believes that its ability to print in a variety of industrial materials, as well as its industry-leading volumetric output (as measured by build box size and printing speed) uniquely position ExOne to serve the needs of industrial customers.
