The Multi Jet Fusion HP PA 12 to produce in small and medium series

Axis was equipped with Multi Jet Fusion HP technology in July 2017. Since then, we have been doing our utmost to promote this technology for the production of small and medium series.

The Multi Jet Fusion HP is a machine that allows the production of powder sintered models. At Axis, we only use PA 12 material.

This printing technique alternates between several stages.

• First, the first consists in depositing a layer of powder by a carriage in the manufacturing chamber.

• Then, a second pass is made by another carriage which deposits fusion and contour agents. When the cart in charge of depositing the various agents is returned to the rear. Fusion lamps allow you to sinter different materials. The manufacture of the parts will therefore be carried out successively thanks to the ventilation which will cool the assembly to harden the material layer by layer as it passes.

• Once the parts have been produced, it is important to allow the assembly to cool. If the parts leave the machine too early, there is a high risk of deformation due to the heat of the sintered parts. The cooled parts are then extracted from their cooling station and powdered.

The Multi Jet Fusion HP can produce a large number of parts. This process is faster than other 3D printing technologies. Thanks to its speed and mechanical precision, we regularly promote this technology for the production of small / medium series.

For example, we have been working for several years with the company Yellowscan. This company is specialized in the production of topographic devices allowing to obtain centimetric models of terrain in 3D. These devices are installed on drones which, in a few minutes, can establish maps for different uses. Several industrial sectors acquire this type of material to facilitate their work (archeology, civil engineering or mining).

As part of this collaboration, we produce parts in Multi Jet Fusion HP with different types of finishes. The objective with this material is to obtain technical and resistant parts in a relatively short time. This 3D printing technique which allows rapid production of series of parts. Multi Jet Fusion therefore makes it possible to obtain small and medium series in a shorter time than vacuum casting.

These are sintered parts, the initial porous appearance must therefore be smoothed with a primer applied in one or more coats. Following this, it is possible for our modelers / modelers to apply a paint finish according to the predefined specifications. Our teams are able to cross-type samples provided by the customer or to do color research to obtain a unique color. Likewise, it is possible to apply other types of finish such as black coloring which transforms the initially charcoal gray color of the parts or to add graining to the parts.
