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
