Selective Laser Sintering : additional production capacity
5 February 2019

Sintering powder: an additional machine

Sintering powder: characteristic of the "new"

Axis has just acquired a new selective laser sintering machine. This is the DTM "Sinterstation 2 500 Plus"!

For the moment, it can produce parts in PA 12 or PA loaded glass, like the machine (HQ Sinterstation) already in our possession.

Its capacity is 350 x 300 x 420 mm (same as its grandfather) because they are the same machines, they were revised both with new heating systems for an optimal production.

The Sintersation 2500 Plus DTM is operational for 3D printing your prototypes and models.

Check your performances by yourself!

Powder sintering: How does it work?

Selective Laser sintering is a method of manufacturing prototypes by additive manufacturing, just like stereolithography. The principle of this technology is to polymerize the polyamide powder, among other things, to solidify it in successive layers of 0.10 mm thanks to a 3D file or a digitized model.

The construction of the selective laser sintering part begins with the platform flush with the machine's construction surface. A powder thickness is deposited using a roller. Once closed, it warms up to reach a certain temperature in the cockpit construction. When this temperature is reached, the laser starts, goes through the lens and moves according to the trajectory calculated by the pilot computer to trace the contours of the part. In contact with the laser, the powder becomes compact and welded because the heat is increased at this precise location to reach the melting point and sinter the material. The platform of the selective laser sintering machine goes down by 0.10 mm, then a new layer of material is deposited on top. The different stages follow each other. After all the successive layers produced, the temperature of the cabin descends again, the whole production can be accessible. Then, like archaeological excavations, using brushes and tools we come looking for the prototypes produced. Parts are then powdered, sanded, ... to remove any excess powder still present.
