Work described in the technical report is about the Rapid Prototyping in sub-task of the research project HTA with reference to the activities of JRP7. In particular, attention will be focused on the production of propellers for hydrodynamics experiments in naval field at model scale. The type of material chosen for the propeller is based on different materials and production techniques Have been selected processes for construction by sintering with 3D metal powder laser printer and the in ABS. The work will be devoted to model propeller production taking as reference an INSEAN stock propeller (INSEAN Model E.779) on which there is extensive technical documentation and reference tests. Perspective of this study is to find a system that ensures rapid prototyping and low cost as possible by comparison with traditional method. In the first part this report will describe the production techniques considered for our purposes, while the second will describe the chosen process applied to the propeller of interest E779 The experimental data will be collected in the next phase of comparison with the original propeller (E.779) made in bronze taken as reference for hydrodynamic measurements.
