In a significant stride toward circular manufacturing, the BMW Group is transforming waste into value by repurposing used 3D printing powder and old plastic parts into new, high-quality components. This bold move not only enhances production efficiency but firmly aligns with the company’s sustainability vision.
At the heart of this innovation is BMW’s Additive Manufacturing Campus in Oberschleißheim, a technological nerve center where research, production, and training in 3D printing converge. Here, up to 12 tonnes of previously discarded powder and plastic waste are reprocessed annually into filament and granulate — essential raw materials for 3D printing. The recycled filament, wound onto spools like wire, feeds Fused Filament Fabrication (FFF) printers, while granulate is utilized in Fused Granulate Fabrication (FGF) for larger tools and parts.
From Idea to Implementation: A Circular Milestone Since 2018
The journey began in 2018 with the “bottleUP” project, a BMW Start-up Accelerator initiative that explored repurposing PET bottles for 3D printing. Within a year, the team moved from concept to pilot-scale filament production using industrial waste. By 2021, BMW’s Predevelopment Non-Metals team, led by project manager Paul Victor Osswald, successfully printed the first auxiliary production devices from their own recycled materials.
“I’ve been involved with this project from the very beginning, and I’m thrilled to see how far we’ve come,” said Osswald. “The use of waste powder and discarded 3D printing components is a key element of a functional and efficient circular economy.”
Empowering the Global Production Network
The Additive Manufacturing Campus is not just a production site — it’s a global hub that distributes recycled filament and technical expertise to BMW Group plants worldwide. Each location receives a tailored support package that includes compatible printer recommendations, validated parameter settings, and extensive training opportunities. This ensures consistent print quality across the board, no matter the site.
The Campus’s knowledge-sharing network has also grown rapidly, enabling BMW sites to innovate independently. One such example is Plant Debrecen in Hungary, which will soon launch its own 3D printing facility, drawing on the experience of its sister plants.
Efficiency on the Ground: Real-World Applications
3D printing is now integrated into every BMW Group production facility, with several hundred thousand components produced each year. The applications are diverse — from safety enhancements and ergonomic aids to fitting tools, templates, and complex fixtures.
- In Munich, 3D-printed components help align the steering rod during the “marriage” of the chassis and body — a crucial moment in the vehicle assembly process. The parts are temporarily installed, guiding components precisely and then removed for reuse.
- In Berlin, BMW Motorrad uses bespoke 3D-printed pedestals for trim decor application. These fixtures lock the parts securely in place, ensuring accuracy and repeatability.
- At Plant Dingolfing, workers designed their own 3D-printed screw holders for cordless tools, minimizing the risk of losing screws during assembly and improving workflow efficiency.
Fast, Flexible, and Future-Proof
The beauty of 3D printing lies in its flexibility. Production teams can respond rapidly to new challenges, with some parts printed and installed within hours. This not only cuts lead times but also reduces potential assembly line downtime. The technology fosters a culture of on-site creativity, empowering employees to solve problems in real time.
BMW’s approach exemplifies how advanced manufacturing can harmonize innovation, cost-effectiveness, and environmental responsibility. With recycled filament forming a key piece of its production puzzle, the company proves that cutting-edge technology and circular economy practices can — and should — go hand in hand.
As Osswald and his team continue to push the boundaries of additive manufacturing, one thing is clear: BMW is not just printing parts — it’s printing the blueprint for the future of sustainable automotive production.
