Experimental Investigations on Biodegradable Polymer Fabricated Using Extrusion-Based Additive Manufacturing

The utilization of additive manufacturing (AM) techniques has revolutionized modern manufacturing processes, allowing for the production of intricate geometries with enhanced design flexibility. Within this context, the exploration of biodegradable materials for AM applications has garnered significant attention due to their environmentally friendly characteristics and potential for sustainable manufacturing. This paper focuses on the experimental analysis of a biodegradable polymer, specifically polylactic acid (PLA), fabricated using extrusion-based AM. Tensile and compression testing, conducted in accordance with ASTM standards, provides valuable insights into the mechanical properties of the PLA components. Additionally, during the fabrication process of the specimens, two different infill orientations (0° and 90°) were employed and analyzed. By incorporating these distinct infill orientations, the study aimed to assess the influence of infill pattern orientation on the mechanical behavior of the fabricated specimens. The analysis of these different infill orientations provides valuable insights into the structural integrity and performance of the specimens under various loading conditions, further enhancing our understanding of the impact of infill orientation on the mechanical properties of the biodegradable polymer components. The experimental analysis contributes to a comprehensive evaluation of the mechanical behavior of the biodegradable polymer, supporting advancements in AM technologies and promoting sustainable manufacturing practices.
