Influence of FDM printing parameters on the compressive mechanical properties and fracture of ABS material

In this paper, the influence of the infill pattern and infill density on the compressive mechanical properties of additively produced ABS material samples was discussed. The compressive mechanical properties of the material are very important and have a great influence on the behavior of the parts in exploitation. The compressive mechanical properties of the ABS material depending on the printing parameters using FDM technology were determined using the compressive test according to the ASTM D695 standard. In the experiments, two infill patterns (hexagonal and rectangular) and three values ​​of infill density (10%, 40% and 70%) were varied. Based on the results of the research, the influence of the infill pattern and infill density on the compressive properties of the additively produced sample was determined. It was concluded that the parts with rectangular infill pattern have better mechanical properties and that increasing the infill density leads to higher values of mechanical properties.
