Industrial-scale 3D printing advances at BMW Group

The BMW Group is taking the next step in the systematic integration of additive manufacturing. Its aim is to scale additive manufacturing up to industrial levels and firmly establish it in various areas – primarily vehicle development and production – to positive economic effect.

Daniel Schäfer, Senior Vice President for Production Integration and Pilot Plant, BMW Group, said: “Processes such as additive manufacturing help us to speed up development cycles and get our vehicles to series maturity faster. 3D printing also shortens the production times of components while meeting rigorous quality requirements.”

Since the middle of 2020, the BMW Group has been additively manufacturing metal and polymer parts for Rolls-Royce Motor Cars. They are made at various points in the process chain and different sites across the global production network. The components concerned are for the vehicle body and passenger cell, and are highly functional and rigid. The process for manufacturing them was developed and prepared for application in automotive production by the BMW Group, at the company’s own Additive Manufacturing Campus, which also produces polymer parts by multi-jet fusion and selective laser sintering.

At BMW Group Plant Landshut, metal parts are currently made by laser beam melting. In production, the metal 3D-printed components are fitted to car bodies in an almost entirely automated process.

The degree to which additive manufacturing can be used in parts production was ascertained in the early stages of the vehicle development. Engineers as well as production and materials experts examined hundreds of components, focusing on the economic benefits of the new technology, and on the weight and geometry advantages compared with conventionally manufactured parts. Components were selected for 3D printing based on a series of criteria and requirements, which were defined and translated into “machine language” with the help of data scientists. This marked the start of a new AI system enabling the BMW Group to identify faster and earlier the components which could potentially be produced by 3D printing.

“Parts that had previously been virtually impossible to realise are engineered by generative design, which uses computer algorithms for rapid component development. Together, experts and computers create parts that make the best possible use of materials in production. Many potential applications are only possible at all thanks to generative design, and 3D printing technologies are particularly suitable for creating their complex forms and structures, which were previously impossible to produce with conventional tools,” said BMW.

“For the BMW Group, generative design resulted in topology-optimised solutions, where form and function have been significantly enhanced. The components are around 50 per cent lighter than comparable conventional components and make the best possible use of the space available, as is the case with the damper for the rear lid,” it added.

Since June 2021, the BMW Group has pooled its entire technology expertise at the Additive Manufacturing Campus just outside Munich, Germany. The new campus also provides training for associates from around the world to use the new technologies and is the home of BMW’s prototype component production. The centre of excellence currently has up to 80 associates and already operates about 50 metal and polymer processing systems. A further 50-plus systems are operating at other production sites around the world.
