UK supplier Filamentive launches rPA12 nylon filament from 100% recycled MJF powder

Filamentive launched rPA12 on February 24, 2026, a nylon 12 (PA12) filament produced from 100% recycled Multi Jet Fusion (MJF) powder waste. The UK-based materials supplier framed the product as a direct reuse of post-process waste from MJF powder, positioning rPA12 as a sustainable feedstock option for filament users.

Filamentive bills itself as a sustainable 3D printing filament supplier and said rPA12 specifically leverages post-process waste from MJF powder. Making a filament from MJF post-process residues is notable because MJF typically generates unsintered or degraded powder during build and depowdering steps; Filamentive’s announcement explicitly ties rPA12 to that stream, rather than to mixed plastic recycling or virgin polymer blends.

The new rPA12 is listed as a PA12 material, which tells machine shops and parts makers the base polymer class Filamentive used. By naming the product rPA12 and specifying “100% recycled MJF powder,” Filamentive signals the material content rather than formulating a recycled mix with unspecified percentages. The company’s UK base and sustainability focus were emphasized in the release that accompanied the February 24 announcement.

Practical implications for shops that run MJF or work with service bureaus are clear from the supply chain detail Filamentive provided: rPA12 is derived from the same Multi Jet Fusion powder that would otherwise enter post-process waste streams. That link could create a tighter loop between MJF production and filament supply if service providers or powder recyclers route post-process powder toward filament manufacturers like Filamentive.

Filamentive’s move adds a distinct recycled option to the nylon filament market by converting MJF powder waste into rPA12 filament. The announcement on February 24, 2026, makes Filamentive one of the UK-based suppliers explicitly claiming 100% recycled MJF powder as the feedstock for a PA12 filament, which changes how buyers evaluate recycled content in technical nylons.

Expect to see follow-up from Filamentive on availability and spool sizes as the company scales production from MJF post-process inputs. For now, the concrete facts are the product name rPA12, the polymer PA12, the feedstock 100% recycled Multi Jet Fusion powder waste, and the February 24, 2026 launch by the UK-based sustainable materials supplier.
