Abstract


The proper selection of equipment for various applications in additive manufacturing (AM) is a critical factor that influences achieving the desired quality of the final product. This experiment compares the print quality of the robotic arm DOBOT Magician with two conventional 3D printers, Creality Ender 3 V2 and Prusa i3 MK2. The experiment involves designing and printing four samples using Polylactic acid (PLA) material and the Fused Filament Fabrication (FFF) method on all three devices. The goal of the experiment is to determine the impact of the design of the devices on the print quality, identify the advantages and disadvantages of each device, and define their application possibilities. The samples are printed under the same conditions and parameters, then 3D digitized using an optical scanner ATOS II Triple Scan and compared in the GOM Inspect software. Through 3D digitization and measurement, we obtained a substantial amount of data concerning the dimensions and tolerance deviations of individual 3D printed test samples. All collected data were subsequently meticulously processed, and the results of the experiment were systematically presented using graphical representation. The results of the experiment provide relevant information for selecting equipment and optimizing the printing process for specific applications. The article presents a valuable contribution to the research in the field of 3D printing and the comparison of various devices enabling 3D printing, opening the path for further experiments and improvements in this area.
