Original abstract

The aim of this paper is to find the most suitable process parameters of the spray gun for the deposition of matte coating for 3D optical scanning purposes. The membrane atomizer-based spray gun is used as a coating device. A suspension of TiO2 and ethanol is used as a coating material. In this study, the formed spray is analyzed using Phase Doppler Anemometry and the results are compared to the deposited coatings. Applied coatings are further examined using a profilometer and 3D scanner to analyze their thickness and the effect they have on the 3D surface reconstruction. The results of this work show that two spray layers are sufficient to evenly apply a coating with good properties for 3D optical scanning purposes. The coating thickness is below 1 μm, reference area is entirely scanned, and the scanned point cloud has a standard deviation from the reference plane below 1.1 μm.
