Abstract

This bachelor thesis deals with the innovative use of Fused Deposition Modeling (FDM) printing technology for the production and testing of Prusament PETG Tungsten 75% samples. The thesis focuses on the assessment of the tensile strength, microstructure and radiation transmittance of the printed samples, with the main objective of analysing the effect of specific material composition and printing process parameters on the resulting properties. In the practical part, a series of experiments were performed using the MK3S+ 3D printer, where samples were printed according to ASTM D638 standard for tensile strength testing, as well as samples for detailed investigation of microstructure and radiation shielding efficiency. The results showed how the Prusament PETG Tungsten 75% material affects key properties of 3D printed objects, opening up new possibilities for practical applications of this material. This work makes an important contribution to the understanding and optimization of the FDM printing process for special applications, particularly in areas requiring materials with high strength and radiation shielding capabilities.
