4. Conclusions The results of the experiment showed that the compressive properties of the ABS material were significantly better in the case when the samples were printed with rectangular infill pattern than with hexagonal infill pattern. Only in the case when the value of the infill density is 10% when the value of the compressive stress is approximately the same. An increase in the infill density leads to an increase in the value of the compressive stress for both types of infill pattern. Given that the S/W ratio was introduced as an indicator, it was concluded that increasing the infill density is very good from the point of view of material utilization. The compressive properties of the material show the behavior of the material when it is loaded with a compressive force, which is the case when the dies for forming thin sheets are made with additive technologies, so it is of significant interest to determine if using the finite element method it is possible to simulate the deformation of polymer hollow structures, which will be one of the directions of further research.
