PA production with fewer emissions

Evonik has developed a new grade of polyamide (PA)12 powders that it says produce fewer CO2 emissions during processing.

The powders replace the company’s existing Infinam polyamide 12 materials that can be used with 3D printing processes such as selective laser sintering (SLS), high speed sintering (HSS) or Multi Jet Fusion (MJF).

The company also plans to develop PA powders with mixed renewable/recycled feedstock and unrecycled raw materials in the production process. According to the company, this enables CO2 reduction in existing plants without changing the quality of the products.

"Alongside factors such as production efficiency or the reusability of materials, our sustainability approach includes the total life cycle assessments of our materials and their consistent improvement.” said Dr Dominic Störkle, head of additive manufacturing (AM).
