This study investigates the feasibility of self-producing polylactic acid (PLA) filament for use in 3D printing. The was fabricated using a desktop single-screw extruder and evaluated against commercially available PLA terms mechanical properties energy consumption. Specimens were printed at two layer heights (0.2 mm 0.3 mm) four infill densities (25%, 50%, 75%, 100%). self-produced exhibited lower diameter precision (1.67 ± 0.21 mm), which resulted mass variability up to three orders magnitude higher than that commercial filament. Thermal analysis confirmed extrusion printing process did not significantly alter thermal PLA. Mechanical testing revealed height consistently yielded stiffness tensile strength all samples. When normalized by mass, specimens with demonstrated approximately double ultimate compared those used consumption indicated improved efficiency, cutting specific 50% increasing material deposition rate proportionally. However, total required print nearly times filament, primarily due waste stems from inconsistencies These findings are significant evaluating practicality particularly performance efficiency.
