Our employees Felix Großwendt and Ulf Ziesing represented the LWT from March 24 to 26 at Tooling 2025, a conference that takes place every three years. This year, the conference was held in Trento, Italy. The thematic focus was on sustainability in toolmaking. In two presentations, the LWT presented current research results from the field of additive manufacturing of tools for hot work, which contribute to reducing the need for resources in toolmaking. In addition, the journey was made by train, which reduced CO₂ emissions by approx. 85% compared to travelling by plane and by approx. 80% compared to travelling by car (calculated using the CO₂ calculator for cars, planes and co. from Quarks).
