Sažetak
The main insufficiency of prototypes made by 3D printing with FDM (Fused Deposition Modelling) method is structure inhomogeneity resulting from the basic principle of this technique. The aim of the paper is to show how the structure of the FDM prototypes, by changing of processing temperature and layout on base plate, is affected. In order to define the processing temperatures influence on building structure of the FDM prototypes, various head and envelope temperatures in printing of specimens were applied. The samples were analysed by computed tomography to determine changes in layers structure, dimensions and the portion of unfilled volume in specimen. Obtained results show that material distribution in the whole volume of scanned specimens is not uniform. It was found out that structure homogeneity represented by the volume of non-filled area is affected by even the shape of fabricated part. This approach can be in the future used as a standard method for quality evaluation.
