Through this work, a static tensile test of polymer test samples was conducted. For the experiment itself, test tubes (1A) are needed, which were made on an Ender 3 Pro 3D printer. According to the ISO 527-2 standard, the dimensions of the test tubes themselves are given with possible dimensional deviations. In addition, the paper describes the devices used, such as a 3D printer and a shredder. The procedures performed during the experiment are explained in detail. The goal is to provide precise and reliable data to enable reliable analysis. The material used is PLA, which was chosen so that the experimental results could be compared with a previous experiment conducted for the HI-PLA material. The test tubes are made with different layer heights and filling percentage and pattern, which gives us more useful information regarding mechanical properties. In this way, we can find the optimal combination of parameters for making test tubes depending on the required tensile strength. In conclusion, the observations on the experimental results obtained are described.
