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.

  • 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
  • COMING SOON: NanoFuse™ — A new line of groundbreaking binders featuring suspended nanoparticles to improve the quality of binder jetting results with certain materials, such as copper and aluminum.
