Diversified polymers for 3D printing

Sirris has just acquired, within the framework of Feder Iawatha, a new polymer powder sintering machine that will enable a larger range of materials to be validated.

To date, the majority of SLS (Selective Laser Sintering) printers have used polyamide. Yet, industrial needs for prototypes and finished parts have become increasingly diversified: they require materials that offer similar characteristics to injected plastics.

Sirris has, consequently, invested in a new Prodways ProMaker P1000 machine which is more 'open' than those previously used at Sirris. Indeed, the machine enables different materials such as PP, PLA, etc. to be used, including flexible plastics such as TPU. It also enables the manufacture of products with a hardness gradient on the same part (in TPU).

The machine, which offers a construction volume of 300 x 300 x 300 mm, is equipped with a 30W CO2 laser with a beam diameter of 450 μm.

It will offer Sirris the opportunity to provide companies with further scope for applying additive manufacturing.
