Axis is always at the cutting edge of technology, with the 3D Multi Jet Fusion printer!

The latest novelty in the domain of 3D printing is something from Axis, which has already existed for several months!

It is an innovative technology for rapid prototyping which uses a Polyamide (PA 12) powder in additive manufacturing: “Multi Jet Fusion”!

“Multi Jet Fusion” is a technology which is close to Powder Sintering. The main differences are that there is no laser for polymerisation of the powder, and the successive layers are 0.08mm; they are finer than they are with Sintering.
This new machine allows for the production of more accurate printed pieces, more rapidly, and with optimal mechanical and thermal properties. One of the several advantages with this machine is that it will apply no shrinkage with your prototypes. This means that your dimensional specifications will be respected.

Our Multi Jet Fusion HP machine is composed of 2 elements.

The first is “the printer”, which creates your prototypes.

The second is the station where the pieces are cooled and the powder removed.

How does it work?

After we have received your 3D files, their production will be started using the specific HP software, and they will be transferred to the printer. Thus, the process for the manufacture of your prototypes using the Multi-Jet Fusion method is as follows:

Once the heat has risen to 140°C in the manufacturing chamber, a first arm will apply a layer of white PA powder (along the Y axis) during a passage.

At the start, a second arm will apply (along the X axis) the black ink with contour agents (details), allowing for fusion which is more or less strong and in this way ensuring better accuracy with smooth surfaces and sharp edges.

With the return of the second arm, the lamps will come along to heat the black areas (which absorb the heat), using ”thermal energy”. The material then rises to 165°C, until it arrives at its fusion point.

Then there will be ventilation to refresh the chamber and lower the temperature of the material so that it will be solidified, but also to cool the 3 printheads that are sensitive to heat.

The piece is now built, with successive layers of 0.10 mm, just like with Sintering Powder or Stereolithography.

Here is the process of polymerization of the material in detail
