What is Multi Jet Fusion?

HP’s Multi Jet Fusion (MJF) is a 3D printing process that produces functional nylon prototypes and end-use parts. It utilizes powdered thermoplastic material to create accurate, complex, and finely detailed parts. They are manufactured in the powder bed, layer-by-layer, and solidified using HP’s unique combination of binding agents and energy.

The nylon thermoplastics used during the MJF 3D printing process deliver optimal mechanical properties and chemical resistance, parts with balanced property profiles, and several layers of biocompatibility.
