Abstract
This study explores the influence of layer thickness on the mechanical properties of Polylactic Acid (PLA) fabricated using Fused Deposition Modeling (FDM) additive manufacturing. By systematically varying the layer thickness (ranging from 0.1 mm to 0.3 mm), the aim is to understand how these changes affect tensile strength, elasticity, and overall structural integrity of the printed components. The research employs a series of controlled experiments, utilizing standardized testing procedures to measure and analyze the mechanical performance of PLA specimens. The tensile strength of the specimens ranged from 35 MPa to 45 MPa, depending on the layer thickness, while elongation at break varied between 5% and 8%. Results indicate significant variations in mechanical properties correlating with different layer thicknesses, providing valuable insights for optimizing print parameters in FDM processes. These findings contribute to the broader knowledge base, guiding the design and manufacturing of more robust and reliable 3D-printed objects.
