Abstract

Recent advances in 3D printing and 3D scanning are poised to improve the state of the art of hydrodynamic scale-model testing. These tools improve the accuracy of the as-built scale model and have a direct influence over the predicted full-scale performance and the confidence level of the designer’s computer simulation.

This thesis explores the subject of accuracy through the development of four 3D printed floating wave energy converter hulls produced with 3D printing. Conceptual and detail design, construction, and measurement techniques are discussed. Financial data is explored as well as time requirements. The ability to use 3D printing to rapidly produce an accurate hull during a basin campaign is of particular interest given the high cost of basin time and limited opportunities for scale model improvements during a test period.

This thesis demonstrated that 3D printing has a place in the portfolio of scale model build techniques. It was successful, however constraints exist from control over machine scheduling to product curing times. These should not preclude existing builders from entering the space. Their expertise will more quickly increase the advancement of these developing processes.
