Asahi Kasei, Aquafil develop 3D printing material combining cellulose nanofiber and recycled PA6

Per a recently signed memorandum of understanding (MOU), technology company Asahi Kasei (Tokyo, Japan) and polyamide 6 (PA6) manufacturer Aquafil S.p.A. (Aco, Italy) are developing a novel material for 3D printing applications combining Aquafil’s Econyl Polymer and Asahi Kasei’s cellulose nanofiber (CNF). The material will be available in either pellet or filament form.

Aquafil’s Econyl Polymer is a chemically recycled PA6 derived from post- and pre-consumer waste, including used fishing nets, old carpets and industrial waste. The material is first depolymerized into monomers, then repolymerized into Econyl Polymer chips.

Asahi Kasei’s CNF is made from cotton linter and is said to feature high heat resistance, network-forming ability and superior material recyclability compared to glass fiber. 

The new CNF/Econyl Polymer compound is reported to feature optimal formability and strength, especially when used in 3D printing. Asahi Kasei sees potential in high-performance aerospace and aeronautical applications. 

The company plans to begin trial sales of the new filament in the EU, U.S and Japan in Q3 2025, and will showcasethe material at upcoming shows such as Fakuma (October 15-19, 2024 in Germany), the Sustainable Materials Expo (October 29-31 in Japan) and Formnext (November 19-22 in Germany).

The development of this material is said to be supported by Itochu Corp., which has made a capital investment in Aquafil.
