The purpose of this work is to demonstrate that rapid prototyping can be effectively applied for fabricating test models to be used in aerodynamic experimental investigations. One of the most popular RP technology used worldwide is 3D printing (3DP). 3D printing technologies can be divided in the following groups: inkjet printing, fused deposition modelling and polyjet. The present work is focused on applications of polyjet technology for manufacturing of aerodynamic parts. This implicitly indicates the effectiveness of employing polyjet technology for fabricating wind tunnel test models. In the second part of the paper is presented a case study using EDEN 350 - 3D printing system by Objet, which is available at Transilvania University of Brasov, Department of Manufacturing Engineering.
