This paper investigates the mechanical properties of products manufactured using Fused Deposition Modeling (FDM) technology from additively reinforced polylactic acid (PLA) materials. With the growing popularity of 3D printing technology, it is necessary to increase and improve the performance of PLA, which is known for its brittleness and limited durability. The aim of this study is to analyze the influence of various additives on the physical and mechanical properties of printed samples. Also, the part of research is to optimize printing parameters to improve overall strength and durability. The basic idea and reason for the observation is to compare regular PLA, which can withstand temperatures of 60°C, and additive PLA, which can withstand temperatures up to 110°C, and its properties in tensile tests exceed those of commonly available PLA. Such additive PLA is not extruded in regular printing and is often excluded from the production process precisely because of insufficient thermal resistance. The results indicate that the use of additives and adjustment of processing parameters leads to a significant improvement in mechanical properties, which highlights the potential of reinforced PLA materials for a wide range of industrial applications. These findings offer valuable insights into research and development in the field of additive manufacturing and may contribute to better optimization of future prints.
