Influence of size on the compressive properties of cellular structures manufactured by additive technologies (FFF, SLS).

Abstract

Abstract The aim of this paper was to compare manufactured cell structures with an appropriately defined formula. Printed models of the hexagonal structure subjected to compression showed that, in the case of the Polylactic Acid Blue material, as the size of the side length of the hexagonal cells increased, the quality of the generated diagrams also increased, which informed the undesired effects of the compressive force in the tests. In the case of cells manufactured from the PA2200 material, it was noted that the maximum force acting on the cell structure decreased with increasing cell side length, however, no undesirable situations occurred during testing in contrast to structures made from Polylactic Acid base materials. In the case of Polylactic Acidmaterials, special attention had to be paid to the Polylactic Acid Gray material. The models were printed with the same parameters, from the same Stereolitography language file, had a slightly higher mass and were subjected to the same compression test, yet showed significant differences in the tests carried out compared to the other models.
