BMW Group Converts Waste Into New Manufacturing Components

BMW Group has developed a recycling system that converts waste 3D printing powder and used parts into new filament for manufacturing production tools and components. The company processes up to 12 tonnes of waste powder annually at its Additive Manufacturing Campus in Oberschleißheim, creating recycled filament and granulate for use across its global production network. The recycled materials are used to produce auxiliary production devices, tools, and various manufacturing aids through Fused Filament Fabrication (FFF) and Fused Granulate Fabrication (FGF) technologies.
The recycling initiative began in 2018 with the “bottleUP” project, which initially focused on converting PET bottles into 3D printing material. By 2019, the company started using industrial waste to produce recycled filament on a pilot basis, and by 2021, BMW successfully printed its first holders and production devices using recycled materials. “I’ve been involved with this project from the very beginning and I’m thrilled to see how far we’ve come – from our initial ideas and attempts at startup level to now being able to produce large quantities of highly robust components from recycled filament at any BMW Group production location,” says Paul Victor Osswald, project manager for Predevelopment Non-Metals.
BMW’s Additive Manufacturing Campus serves as a center of competence, providing other production facilities with recycled filament, optimized printing parameters, and technical expertise. The Campus works with established 3D printing facilities at BMW plants to test suitable printers and develop validated parameter settings for recycled materials. This comprehensive package enables other locations to quickly achieve quality printing results while building local expertise through training programs.
Every BMW Group plant now operates 3D printers, producing several hundred thousand components annually for diverse applications. These include ergonomic solutions for workers, scratch protection, fitting aids, manufacturing equipment, gauges, templates, and specialized tools. Specific examples include components for chassis-body assembly at Plant Munich, support pedestals for motorcycle trim decoration in Berlin, and magnetic screw holders developed by employees at Plant Dingolfing to prevent parts loss during assembly.

17-4 Stainless Steel Comprehensive Guide: In-depth Analysis of Performance, Applications, and Processing Technology
In today’s industrial manufacturing sector, the selection of materials directly determines the performance, lifespan, and cost-effectiveness of the final product. Among numerous high-performance metal materials, 17-4 Stainless Steel (also known as 17-4 PH) has become one of the preferred materials for the aerospace, medical device, petrochemical, and high-end mechanical manufacturing industries due to its unique precipitation hardening characteristics. As a martensitic precipitation hardening stainless steel, 17-4 not only possesses the inherent corrosion resistance of stainless steel but also achieves extremely high strength and hardness through heat treatment. This dual advantage allows it to maintain excellent stability even in extreme environments.

A Comprehensive Guide to Nickel Plating in CNC Machining
In the chain of high-end manufacturing, CNC (Computer Numerical Control) machining is responsible for giving parts their geometric shapes and dimensional accuracy, while surface treatment determines the lifespan, functionality and reliability of the parts. Among various surface treatment processes, nickel plating has become one of the most commonly used post-processing techniques for CNC machined components due to its unique comprehensive properties – combining corrosion resistance, wear resistance, lubricity and excellent appearance.
Whether it is the precision valve bodies in the aerospace field, the aluminum alloy casings in consumer electronics, or the transmission components in the automotive industry, nickel plating plays an indispensable role.
