In this thesis, static tensile testing is conducted on 3D printed specimens shaped according to the ISO 527-2 standard. The specimens were produced using a Zortrax M200 3D printer and filaments made from different materials, including ABS, Z-ULTRAT, and Z-PETG. Filament is a thin strand of material, most commonly plastic, used as a raw material in 3D printing. The aim of the research was to analyze the impact of different materials and printing settings on the mechanical properties of the samples, with a particular focus on tensile strength and elastic modulus. The static tensile test was performed using an Inspekt Blue 20 testing machine, which allows precise measurement of the forces required to stretch the specimens until their fracture. The test results provided a comparison of the mechanical properties of the samples made from various materials, offering detailed insight into their strength and resistance to deformation. The conclusion of the research highlights the significant influence of material type and 3D printing parameters on the mechanical characteristics of the tested specimens, which is of particular importance for the industrial application of 3D printed parts.
