Axis always at the forefront of technology with the 3D Multi Jet Fusion printer!

The latest innovation in the field of 3D printing has already been for several weeks at Axis!

An innovative technology for rapid prototyping that consists of a polyamide (PA 12) powder by additive manufacturing: the “Multi Jet Fusion”!

“Multi Jet Fusion” is a technology that is close to Powder Sintering. The main differences are that there is no laser to polymerize the powder and that the successive layers are 0.08 mm, therefore finer than Sintering.
This new machine makes it possible to produce more precise printed parts, more quickly with optimal mechanical and thermal properties. One of the many benefits of this machine is that no shrinkage is to be applied to your prototypes. Your dimensional expectations will therefore be respected.

Our Multi Jet Fusion HP machine consists of 2 elements.

The first is the “printer” that makes your prototypes.

The second is the chilling and de-dusting station.

How it works?

After receiving your 3D files, launching production with the specific HP software and transfer them to the printer, the process of manufacturing your prototypes by the Multi-Jet Fusion process is as follows:

Once the heat has risen to 140 ° C. in the manufacturing chamber, a first arm will deposit a layer of white PA powder (along the Y axis) during a passage.
Firstly, a second arm deposits (along the X axis) the black ink with contouring agents (details) allowing the fusion to be more or less strong, thus giving a better accuracy, smooth surfaces and sharp edges.
When returning the second arm, the lamps heat the black areas (which absorb heat) by the “thermal energy”. The material then rises to 165 ° C to reach its melting point.
The ventilation then refreshes the chamber to lower the material temperature in order to be solidified, but also to cool the three printheads that are sensitive to heat.
The part is then constructed in successive layers of 0.10 mm, as for Powder Sintering or Stereolithography.
