INFINAM® eCO PA12 contributes to both footprint and handprint circular values. Besides an improved carbon footprint rate due to renewable energy use for production and bio-circular raw material, Evonik’s new polyamide 12 grade provides proven reusability rate of 100 percent of the structure support powder, with a refresh rate of 70/30 of used versus virgin material over several printing cycles, all the while exhibiting excellent processability and stable mechanical properties of 3D printed parts.

Evonik’s formula to drive circular plastics economy is based on four main cornerstones:

• reuse
• reduce
• renewable
• recycle

In addition to factors like production efficiency or reusability of materials, Evonik’s circularity approach includes the total life cycle assessments of its PA12 formulations and their consistent improvement. The specialty chemicals company looks at carbon footprint along with other important factors such as water consumption and land use. By using renewable energy and renewable or recycled feedstocks for production, the group significantly improves the overall eco-balance of its materials. In looking ahead, Evonik is exploring new end-of-life opportunities for PA12 powders to fully close the loop.

The "eCO" description stands for the company's goal of avoiding the greenhouse gas carbon dioxide by using renewable or circular raw materials via the mass balance approach. This method enables an immediate reduction of CO₂ in existing plants quality of the products.

Evonik’s 3D printing activities are bundled in the group’s Additive Manufacturing Innovation Growth Field. The strategic focus here is on developing and manufacturing industrial, ready-to-use high-performance materials for all major polymer-based 3D-printing technologies. In this way, Evonik can drive 3D printing as a large-scale industrial manufacturing technology along the entire value chain. The Additive Manufacturing Innovation Growth Field’s product range is marketed under the new INFINAM® brand.
