Multi Jet Fusion

Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts in as fast as 1 day. Final parts exhibit quality surface finishes, fine feature resolution, and ‬more consistent mechanical properties when compared to processes like selective laser sintering.

Multi Jet Fusion design guidelines will help you understand capabilities and limitations.

Why Choose Multi Jet Fusion For Your 3D Printing Project?

MJF offers engineering grade materials with great overall properties. Additionally, MJF offers enhanced surface finish, finer features, more consistent mechanical properties, and faster build times.

How Does Multi Jet Fusion Work?

Multi Jet Fusion uses an inkjet array to selectively apply fusing and detailing agents across a bed of nylon powder, which are then fused by heating elements into a solid layer. After each layer, powder is distributed on top of the bed and the process repeats until the part is complete.

When the build finishes, the entire powder bed with the encapsulated parts is moved to a processing station where a majority of the loose powder is removed by an integrated vacuum. Parts are then bead blasted to remove any of the remaining residual powder before ultimately reaching the finishing department where they are dyed black to improve cosmetic appearance.

Watch: Multi Jet Fusion: What is This Used For?

For fast, quality results, Multi Jet Fusion (MJF) is unparalleled as a 3D printing process. It’s able to produce functional nylon prototypes and end-use production parts in a single day, featuring quality surface finishes and fine feature resolution. It also offers more consistent mechanical properties than similar processes like selective laser sintering.

Using an inkjet array to repeatedly apply fusing agents across a bed of nylon powder, followed by fusion into a solid layer via heating elements, MJF is able to offer complex and detailed features. Protolabs offers a commercial-grade unfilled Nylon 12 material to create durable parts. Multi Jet Fusion offers a fast and advanced way to create parts on demand.
