The development of a combined process chain of additive manufacturing processes addresses the production of topologyoptimized structures. Using AI-monitored robotics, the reinforcement of large train segments is realized. The additive processes used and technological development results are described.defalseAdditive ManufacturingAutomationLightweight DesignRoboticsTopology OptimizationAdditively Manufactured Lightweight Constructionfor Rail Vehicles Topology-optimized Lightweight Structures for Stiffening Vehicle Segments in Rail Transport Additiv gefertigter Leichtbau für Schienenfahrzeuge Topologieoptimierte Leichtbaustrukturen zur Versteifung von Fahrzeugsegmenten im Schienenverkehrjournal article
