Multi Jet Fusion (MJF)

Multi Jet Fusion (MJF)

Multi Jet Fusion is an industrial 3D printing process used for the rapid manufacture of prototypes, and quality production parts. The end-use parts exhibit isotropic properties in all axes, which translates to consistent mechanical properties throughout the part. This results in as printed parts that require little post-processing, and parts exhibit many properties including vibration dampening, durability and water-tightness.

An MJF part is comparable to parts created by injection molding and is stronger than components created by fused deposition modelling, which is why MJF technology is the 3D printing solution for functional parts in many industries.

Multiple build platforms and ISO-certified processes enable GoProto’s MJF printers to run around the clock, 7 days a week. Whether it is one part or one hundred, MJF and GoProto enable the production of end-use custom parts in your hands in as little as 2 days.

How does Multi Jet Fusion work?

An MJF printer uses an inkjet array to selectively apply both fusing and detailing agents across a bed of nylon powder. After that, heating elements fuse each layer into a solid, layer by layer until the parts are complete. Completed builds are then moved from the printer to a processing station to be cooled, recycling the loose powder for the next build. De-powdered parts are bead blasted to remove residual powder before post-finishing to customer specifications.
