TU Dortmund University expands 3D printing research with new WAAM machine from GEFERTEC

The Technical University of Dortmund has expanded its range of additive manufacturing processes by integrating the Wire Arc Additive Manufacturing (WAAM) process. The Chair of Materials Technology in the Faculty of Mechanical Engineering is now using the arc405 machine from GEFERTEC to efficiently produce larger and more complex metal components. The decision in favor of GEFERTEC was made after a comprehensive Europe-wide market research, with the ability to process titanium being the decisive factor.

“WAAM is particularly suitable for large components,” says Manuel Pinho Ferreira, research assistant at the chair, citing one of the strengths of the process. The WAAM process is based on gas metal arc welding and enables components to be built up in layers using wire as the starting material. This leads to high build-up rates and cost-efficient use of materials.

The arc405 machine has five axes and can print components measuring up to 680x680x580 mm. With build rates of up to 600 cm³ per hour, near-net-shape workpieces with a maximum weight of 200 kg can be produced. The combination of high efficiency and the use of cost-effective materials makes WAAM an attractive option for industrial applications and research.

Both industry-related research projects and basic research are carried out at the chair using the new system. The arc405 makes it possible to further research innovative manufacturing technologies and test their application in various industrial areas. By expanding its process portfolio, TU Dortmund University is positioning itself as an important player in the field of additive manufacturing technologies.

The introduction of WAAM technology at TU Dortmund University is helping to further expand the possibilities of 3D printing in the metal sector and offers new perspectives for the development of complex and high-performance components in research and industry.
