HP Multi Jet Fusion for small and medium production runs

Axis is equipped with Multi Jet Fusion HP technology as of July 2017. Since then, we have been doing our best to promote this technology for small and medium-sized production runs.

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

This 3D printing technique is done in several steps.

– The first step consists in depositing a layer of powder by a carriage in the manufacturing chamber.

– Then, a second pass is made by another carriage that deposits fusing and contouring agents. When he returns, he is in charge of dropping off the various agents. The fusion lamps allow you to sinter the different materials. The manufacturing of the parts will be done successively. Afterwards, a ventilation system will cool down the material to harden it layer by layer.

– Once the parts have been produced, it is important to let them cool down. If the parts are taken out of the machine too early, there is a high risk of deformation due to the heat of the sintered parts. Finally, the cooled parts are removed from their cooling station and dewaxed.

The HP Multi Jet Fusion can produce a large number of parts faster. Due to its speed and mechanical precision, we favor this technology for small/medium series production.

For example, we have been working for several years with the company Yellowscan. This company is specialized in the production of topographic devices producing 3D centimetric terrain models. These devices are installed on drones which, in a few minutes, can draw up various maps. These tools are used for different purposes (archaeology, civil engineering or mining).

As part of this collaboration, we produce parts in HP Multi Jet Fusion with different types of finishes. The objective with this material is to obtain technical and resistant parts in a relatively short time. It is also a 3D printing technique that allows to launch in production and thus to obtain small and medium series in a shorter time than the vacuum casting.

In the case of sintered parts, the initial porous appearance must be smoothed with a primer applied in one or more layers. Following this, it is possible for our modelers to apply a paint finish according to the specifications of our customer. Our teams are able to counter-type samples provided by the customer or do color research to obtain a unique color. In the same way, we can apply other types of finishing such as black coloring that transforms the initial charcoal gray color of the parts or add a graining to the parts.
