Multi Jet Fusion (MJF) Services

Multi Jet Fusion (MJF) is a highly accurate additive manufacturing technology combining short lead times with high output in terms of volume. MJF is popular because it offers good mechanical properties and a low part cost.

How MJF works

How MJF works

Multi Jet Fusion is a powder bed fusion technology that builds up the manufactured parts layer-by-layer.

First, a movable unit distributes a thin layer of thermoplastic powder. Another movable unit, moving in the orthogonal direction, is equipped with two infrared lamps and a dosing system for the agents to be distributed on the powder bed. The first lamp preheats the powder bed to just below the melting point. Unlike other additive manufacturing technologies, MJF does not require an energy-consuming laser.

Next, the fusing and detailing agents are then applied. Finally, another fusing lamp is attached to this moving unit, fusing the powder to the underlying layer where the fusing agent was applied. This fusing agent increases the absorption of the material for infrared radiation and ultimately causes the grayish discoloration of the components. The detailing agent evaporates during this process and ensures no surrounding powder melts onto the contour. This process ensures sharp edges and dimensional accuracy.

This process begins again for the next layer. 

MJF Use Cases

Multi Jet Fusion is usually used for prototypes and functional prototypes. This technology is especially suitable for prototypes that require good mechanical properties (e.g., prototypes for injection molding parts) or need to be used for testing. It is also capable of producing high-quality end-use parts. Plus, unused powder can partially be reused for the next production cycle

As most MJF materials are biocompatible, the technology is often used for orthotics and prosthetics.

Available MJF finishes


An abrasive medium is applied to the component under high pressure. By using different media (e.g., corundum, sand or glass beads), functional (achieving a certain surface roughness) and optical (polishing the surface) finishing can be performed.

Color dyed

The plastic component is immersed in a water bath. The resulting chemical reaction causes the dye to penetrate the component. This provides homogeneous color gradient and an unchanging but more scratch-resistant surface.


Additional color is applied to the printed part, often by a professional spray-painting system. To get the desired output, the part is properly prepared through accurate cleaning and a clearcoat.


Using sandpaper, sanding smooths the part and removes any obvious blemishes, such as support marks or blob. The chosen sandpaper depends on the layer height and print quality desired.


The sealing process is performed with an aqueous solution to close the outer surface or skin of the part and fill in small pores. The sealing solution is either manually applied or dipped, depending on the part’s geometry.


In the smoothing process, the plastic component is reworked by a chemical reaction. The top layer of the component is dissolved by a medium in a solution bath and the result is a very smooth surface.


Parts are reworked by grinding media in a container, where they are deburred, finely ground, and polished by vibration or rotation of the container.
