The feasibility of experimentally testing 3D printed propellers was investigated at Reynolds numbers where scale effects were significant. Hama strips were printed on the leading edge of a B-series model propeller’s blades and open water tests were performed with both unstimulated and stimulated propellers for 𝑅𝑒 = 105 𝑡𝑜 5 × 105 . Two effects were studied, the first being the effect of the 3D-printed material on propeller hydrodynamics at model scale by comparing test results from the naked propeller tests to the original B-series tests at the Netherlands Ship Model Basin (NSMB). Second, the effects of Hama strips on the propeller model test results are studied through comparison of naked and stimulated results at the same test conditions. Finally, the feasibility of the implementation of turbulence stimulators for model propeller testing is discussed.
