# Recycled 3D Filaments BMW Group Closed the Loop on Additive Manufacturing Waste By Grace Mahas | Written with AI assistance | Published 2026-03-04 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/recycled-filament References: [3dprinting](https://3dprinting.com/news/bmw-group-converts-waste-into-new-manufacturing-components/)  Since 2018, [BMW Group](https://www.trendhunter.com/trends/bobsled-footwear) has been quietly building out a [closed-loop recycling system](https://www.trendhunter.com/trends/pakpet-single-pellet-solution) at its [Additive Manufacturing Campus](https://www.trendhunter.com/trends/Additive-manufacturing-scaling) in Oberschleißheim — one that now processes up to 12 tonnes of waste 3D printing powder annually. The recovered material gets converted into filament and granulate used across BMW's global production network via Fused Filament Fabrication and Fused Granulate Fabrication technologies. What started as a PET bottle upcycling pilot called "bottleUP" has scaled into a full manufacturing input stream, with the Campus now supplying other facilities with recycled filament, validated printing parameters, and technical training. The output is concrete and plant-wide. Every BMW Group facility now runs 3D printers producing several hundred thousand components per year — ergonomic worker aids, scratch protection, assembly gauges, magnetic screw holders, and chassis support components among them. The Campus functions less like an R&D experiment and more like an internal supplier, embedding recycled material into everyday production rather than treating sustainability as a separate initiative.
