This study presents an experimental investigation into the tensile behavior of threads and specimens fabricated using polylactic acid (PLA) filament via fused deposition modeling (FDM). While tensile properties of bulk PLA samples and structural components have been widely explored, the mechanical performance of isolated, stand-alone printed threads remains underreported. Such analysis is vital given that the integrity of thin structural surfaces is heavily dependent on the strength and stability of their embedded threads. To investigate this topic, PLA threads were printed using controlled parameters and subjected to standardized tensile testing. Key mechanical properties, including ultimate tensile strength, elongation at break, number of threads and Young’s modulus, were determined, compared and discussed. These results provide a foundation for optimizing printing procedures and techniques towards adaptive printing
