3D Spark receives green light from Deutsche Bahn
Hamburg, 18 September 2025
The Hamburg-based start-up 3D Spark has reached a significant milestone: Deutsche Bahn has approved the company's CO₂ reporting tool for the production of on-demand spare parts. This decision underscores the growing importance of sustainability and efficiency in the manufacturing industry. The tool enables precise and automated calculation of the carbon footprint for each component produced, broken down by material, manufacturing process and post-processing. This allows Deutsche Bahn to make informed decisions about reducing its environmental impact while increasing the efficiency of its production processes.
The founding team of 3D Spark, consisting of Fritz Lange, Ruben Meuth and Arnd Struve, originally comes from Helmut Schmidt University – University of the Federal Armed Forces Hamburg (HSU). During their start-up phase, they were supported by Felix Krieg, an experienced start-up advisor at Startup Port @TUHH. This cross-university collaboration between HSU and the Technical University of Hamburg (TUHH) reflects the successful network of the Startup Port association, which promotes innovation and supports exchange between different universities and institutions.
The integration of 3D Spark's CO₂ reporting tool into Deutsche Bahn's production processes is an example of the successful implementation of sustainable technologies in industry. It shows how start-ups can develop innovative solutions that have a positive impact on the environment and the economy through targeted support and cooperation with universities and consulting networks.
