Výzkum mechanických vlastností materiálů vyrobených aditivní technologií FDM

Abstract

The dissertation discusses the cost-effective FDM technology (Fused Deposition Modeling) that enables the printing of fully functional metal parts using the multi-material filament Ultrafuse 316L. It describes the entire production process and highlights the significantly higher affordability of FDM technology compared to more expensive laser technologies like SLM (Selective Laser Melting), commonly used for printing metal alloys. Based on published scientific findings, the dissertation proposes an experimental activity plan that includes various tests, not only of mechanical properties but also, for instance, of corrosion resistance. The tests are evaluated, and the results are discussed, particularly concerning the usability of using FDM technology for printing metal parts. The printed alloy exhibits reduced mechanical properties and inferior material characteristics, primarily due to the omnipresent porosity in the material. Consequently, an experimental method is implemented at the end of experimental activities to reduce porosity. The text provides a comprehensive overview of the properties of metallic products produced by FDM technology, from which potential application possibilities are derived.
