    Evaluation of 3D printed aerofoil models for wind tunnel testing.
    (Stowarzyszenie Inżynierów i Techników Mechaników Polskich, 2014) Olasek, Krzysztof; Wiklak, Piotr
    Preparation of an appropriate model to conduct experiments is a crucial aspect of every science investigation. Usually, apart from the requirement to achieve a desired level of a model quality, it is also very important to keep in mind the costs and time of its manufacturing. The following paper provides an overview of various 3D printing techniques. Four models of a standard NACA0018 aerofoil were manufactured in different 3D printing methods. Various parameters of the models have been included in the analysis: surface roughness, dimension tolerance, strength, details quality, surface imperfections and irregularities as well as thermal properties.
