The ExOne Company and Global Tungsten & Powders Corp. (GTP) entered into a collaboration to advance tungsten-based metal 3D printing using binder jetting. Binder jetting is a 3D-printing process that uses a digital file to inkjet a bonding agent into a bed of powder particles, creating a solid part one layer at a time. The new ExOne-GTP collaboration focuses on the development of two metal matrix composites: cemented carbide (WC-Co), a material with very high hardness and toughness that is widely used for the production of cutting tools and wear-resistant parts; and copper-tungsten (CuW), which is used in applications where high heat resistance, high electrical and thermal conductivity, and low thermal expansion are needed.

GTP will offer a 3D-printing and sintering service for cemented carbide parts using an ExOne Innovent, an advanced binder-jetting system that 3D prints metal, ceramic and composite powders in a compact build area.
