Tech start-up LEAM has succeeded in improving plastic 3D printing through light alone. This is made possible by high-performance LEDs and the targeted delivery of focused light to the component. The three founders got to know each other during their time at the Chair of Carbon Composites at the Technical University of Munich (TUM) and have now used their knowledge to solve industrial problems. In the future, the new technology will enable companies to print complex structures at an exceptionally high component quality at a low cost.
