Abstract:

This paper presents a study of the effect of chemical treatment using pure acetone on strength specimens made from PLA polylactide produced by 3D FDM/FFF printing technology. The strength specimens were designed in accordance with the ISO 527 standard. The chemical treatment was carried out using baths at different time intervals. The hardness of the samples was measured, and a tensile test was performed. The results show that with prolonged contact with acetone, the hardness of the material decreases by approximately 45% compared to untreated samples. When analysing the tensile tests, it was noted that the tensile strength decreases with longer chemical bath time. At the same time, the material becomes more ductile, resulting in a high elongation at break in tension of up to 40% relative to untreated samples.
