Multi Jet Fusion (MJF)

MJF – Multi Jet Fusion

MJF 3D Printing 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 moulding and is stronger than components created by fused deposition modelling, which is why MJF 3D Printing technology is an ideal solution for functional parts in many industries.

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

How does MJF 3D Printing 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.

Yes, Multi Jet Fusion excels in handling complex and intricate geometries, offering remarkable accuracy and resolution. This commendable capability positions it as a prime option for crafting parts characterised by intricate details and fine features.

Multi Jet Fusion serves a diverse range of industries including automotive, aerospace, medical, consumer goods, robotics, UAV drones, and beyond. Its proficiency in efficiently generating functional, ready-to-use parts renders it highly beneficial across a spectrum of sectors.

Multi Jet Fusion distinguishes itself by its capacity to manufacture parts with isotropic properties, maintaining consistency across all directions. This distinctive feature sets it apart from certain other methods and renders it particularly suitable for specific functional applications.

Multi Jet Fusion parts usually undergo post-processing steps like cleaning, bead blasting, dyeing, or surface finishing. These steps are employed to fulfil specific aesthetic or functional prerequisites. The necessity for post-processing is contingent upon the intended application of the part. Unprocessed Multi Jet Fusion parts exhibit a grey hue due to the utilisation of black ink and white powder in their creation. For this reason, Formero dyes all parts black to impart a striking visual appeal.
