Filamentive utilizes MJF waste powder to develop FDM 3D printing filament.

September 27, 2025 Materials 114

Filamentive is developing sustainable FDM filament from waste HP MJF nylon powder to create a closed-loop solution for 3D printing.

The British sustainable 3D printing materials company Filamentive recently announced that it is developing an innovative FDM 3D printing filament, the raw material of which comes from waste nylon powder generated in HP's Multi Jet Fusion (MJF) 3D printing process. This initiative aims to create a closed-loop, more sustainable material solution for the industry.

As a mainstream industrial-grade 3D printing technology, MJF produces a large amount of unsintered PA12 (Nylon 12) powder during the printing process that is difficult to reuse directly. Filamentive's R&D project is precisely aimed at reprocessing and modifying these powders, which are usually treated as waste, into high-quality filament suitable for desktop FDM printers.

This is an excellent example of a "circular economy" within the 3D printing industry. It not only finds a high-value reuse pathway for large amounts of industrial waste, reducing the environmental burden, but also provides FDM users with a more cost-effective and environmentally conscious material choice. This kind of innovation, which connects different processes and achieves a closed resource loop, is a key step in driving the entire additive manufacturing industry toward sustainable development.
