ExOne enters tungsten 3D printing partnership with World Tungsten & Powders Corp

Binder jet 3D printer supplier ExOne has entered right into a collaboration with World Tungsten & Powders Corp. (GTP), a metallic powder producer headquartered in Towanda, Pennsylvania. On this settlement, the 2 events will work to advance the usage of tungsten powders in metallic binder jet 3D printing. The work is predicted to have excessive affect within the manufacturing of chopping instruments, wear-resistant components and purposes the place excessive electrical and thermal conductivity is required.

“Metallic 3D printing utilizing our unique method to binder jetting has thrilling and vital penalties for a wide range of producers, together with those that make components with cemented carbide and different tungsten composites,” feedback Tim Pierce, ExOne Vice President of Metallic Business Merchandise. “Our newest improvement collaboration with GTP will assist advance the supplies essential to ship on the imaginative and prescient of manufacturing these components sooner, with much less waste and extra geometric design freedom.”

Tungsten has the best melting level of all found components, incomes it “the Satan particle” nickname when it’s discovered as a contaminant in different powders. With this worth nonetheless, comes a exceptional robustness, and it’s steadily mixed with different components to make heavy metallic alloys, used to make rocket nozzles, turbine blades, and different high-wear elements.

ExOne 3D printers, together with the X1 25PRO and the Innovent+, are already suitable with sure tungsten alloys. On this new partnership with World Tungsten & Powders Corp. although, the corporate might be trying into two new metallic matrix composites: cemented carbide (WC-Co) and copper-tungsten (CuW).

New metallic matrixes for additive manufacturing 

WC-Co is a tough and difficult materials, superior to carbon metal or stainless-steel for the manufacturing of chopping instruments and wear-resistant components. Slicing instruments constituted of the fabric additionally sometimes give higher floor end to elements than when utilizing instruments constituted of different supplies. The fabric is composed of high quality particles of carbide cemented right into a composite by the binder metallic.

CuW, then again, is a heat-resistant, ablation-resistant, extremely thermally and electrically conductive metallic matrix. Instance purposes of this materials embrace  electrodes for electrical discharge machining, semiconductor gadgets, and contacts for vacuum, oil, and fuel methods.

Commenting on the standard manufacturing of the these composites Deborah West, Vice-President Enterprise Unit Refractory & Specialty Powders at GTP, explains, “Historically tungsten carbide powder is pressed into the specified form after which sintered to offer it energy and density.” By processing these supplies through binder jet 3D printing as an alternative, the companions will have the ability to cut back prices and enhance geometric complexity. “As a substitute of pricey and well timed mildew development,” West provides, “the components now may be printed straight within the desired form, nonetheless utilizing sintering expertise to realize the ultimate energy.”

As a market chief for any such powder, West provides that GTP is “excited to work with ExOne within the improvement of cutting-edge expertise for the additive manufacturing trade.”
