With advances in digitization, automation, and artificial intelligence, manufacturing technologies are also constantly evolving. Additive manufacturing technologies offer the possibility of producing customized components with considerable design freedom. Furthermore, compared to conventional manufacturing processes, costs and time can be saved, especially in product development.The first part of the course therefore covers the fundamentals and applications of additive manufacturing in the field of metals and plastics. The second part of the lecture focuses on the selection and qualification of metallic materials for use as tools, for example in plastics processing (rapid tooling). The thermal treatments required for this can be evaluated in terms of their efficiency using thermal analysis methods. The thermal treatments required for this can be evaluated in terms of their efficiency using thermal analysis methods. The design of thermochemical surface treatments, such as carburizing and nitriding, is explained on the basis of thermokinetic considerations.
