            Development of an additive production technology for manufacturing
            plastic-based components for maritime applications



            Maritime sealing systems are subject to high mechanical and media stresses   Period
            and are essential for the safe and economical operation of ships. The "stern-  01.04.2021 – 31.03.2024
            tube system" is defined as the components of the ship's shaft system that sup-
            port the drive shaft in the boat's hull and at the same time prevent seawater   Project management
            from penetrating through the drive shaft channel. Due to the varying sizes of   Prof. Dr.-Ing. habil. Maik Gude
            the individual components of the sterntube system and their small quantities
            per ship, they have been produced as large-scale constructions in metallic   Contact
            cast alloys in a time-consuming and cost-intensive reworking process. The   Johanna Maier
            joint project PRILLIAND therefore aims to make the conventional production   Tobias Kastner
            of the highly customized product solutions for the sterntube system compo-
            nents available on the market more efficient in both economic and ecological   Project partners
            terms. Through the use of innovative additive manufacturing technologies in   Wärtsilä Deutschland GmbH
            combination with modern lightweight materials, selected components of the
            sterntube system will be rethought and designed in a way that is both mate-  Funding
            rial- and production-oriented. This significantly increases the weight-specific
            mechanical properties of the previously metallic components. The high de-
            gree of customizability that can be achieved at the same time also enables fast
            and cost-effective adaptation to customer requirements. PRILLIAND conse-
            quently provides the basis for efficient low-volume production of rotationally
            symmetrical large structures for maritime applications.
