3D printing, as an additive process, offers much more than traditional machining techniques in terms of achievable complexity of a model shape.
That fact was a motivation to adapt discussed technology as a method for creating objects purposed for aerodynamic testing.
The following paper provides an overview of various 3D printing techniques. Four models of a standard NACA 0018 aerofoil were manufactured in different materials and methods: MultiJet Modelling (MJM), Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM).
Various parameters of the models have been included in the analysis: surface roughness, strength, details quality, surface imperfections and irregularities as well as thermal properties.
