AbstractThe importance of print quality has increased and the expectations of the printer users regarding the sensitivity and print quality have also increased with the development of 3D printing technologies. In Additive Manufacturing Technologies, environmental factors such as temperature and internal flow, and structural factors such as vibration response are among the fundamental parameters that causes physical and thermal effects on printing hardware. In this study an experimental setup has been implemented to figure out the physical response characteristics such as vibration and temperature variation according to various operating modes. In a conventional 3D printer, the relationship of the vibration between temperature changes was examined during the printing of each layer. By tuning of infill density and infill structure parameters in process settings, it was observed that these parameters influence vibration and thermal characteristics of printing hardware meaningfully. The obtained vibration responses were examined in terms of average value and maximum amplitude magnitudes. Furthermore, the heat generation on critical printer components were investigated both by thermal imaging device and laser thermometer. The components where the thermal load is most exposed were identified as x- and y- axis stepper motors. Finally, optimum operating parameters were determined which create the lowest dynamic stress in the printing system.
