Popis: | Additive manufacturing (AM) is an essential tool to make 3D objects. In the industry and laboratories, quality controls of these objects have to be fulfilled. But these quality controls are challenging compared to classical methods of fabrication because of very complex object manufacturing, unachievable with standard tools. Consequently, we demonstrate terahertz (THz) imaging as an efficient method and THz tomography may be considered as a routine control. This paper proposes an experimental study of 3D polymer objects obtained by additive manufacturing techniques. This approach allows us to characterize defects and to control dimensions by volumetric measurements on 3D data reconstructed by tomography. |
