Metal 3D Printers - Materials & Binders

ExOne metal 3D printers transform more than 20 powders into metal, ceramic and composite parts and products. 

Our metal printing technology creates dense and functional precision parts used for automotive, aerospace, defense, energy, and consumer applications.

To ensure customers will have reliable, repeatable and predictable parts, from 3D printing to final sintering, we have a comprehensive qualification process. ExOne’s R&D teams work continuously to qualify new materials for use in our machines. What’s more, we routinely partner with companies to develop specific materials for binder jet 3D printing with our technology.

ExOne has three qualification levels that recognize different degrees of readiness for customers with different application needs.

ExOne Fuse Binders

One of the reasons ExOne metal binder jet systems can print such a diversity of powdered materials is our portfolio of specialty Fuse binders, which deliver unique benefits for the material being 3D printed.

Binders must deliver certain characteristics that work harmoniously with the powder material being printed. Considerations include viscosity, saturation, bleeding in X and Y, as well as debinding characteristics. ExOne binders continue to be optimized to provide improved green strengths and other beneficial properties based on the material being printed.

Explore Binders

  • CleanFuse — A premium, clean-burning binder that leaves behind no carbon residue and works well with metallic materials negatively affected by carbon, such as Inconel powders
  • FluidFuse — A versatile solvent-based binder with low viscosity that works well with a variety of metallic and non-metallic materials, including ceramics
  • AquaFuse — A water-based binder that works well with a variety of metallic material
  • PhenolFuse — A phenolic binder best suited for printing high-temperature materials, including non-metallics such as carbon, tungsten carbide (WC), silicon carbide (SiC), and other ceramics
