Resistance prediction for high speed vessels (Fn > 0.5) is a challenging task in the early ship design stage. On the one hand, model tests deliver satisfying results, which are on the other hand expensive and time consuming. Testing of different versions of the hull form using model tests in the design process is nowadays not economical. In the last years, 3D printing gained in importance in industrial applications like rapid prototyping. The enhancing quality makes the technology suitable for the production of ship models, as cost and production time can be reduced significantly. Hence, towing different versions of the hull design becomes an alternative to usual approaches. In this paper the application of 3D printed ship models is presented exemplary for a new hull design of a high speed vessel operating at a Froude number of 0.912 using the results of a bachelor thesis.
