Abstract

Fused Deposition Modeling (FDM) is an additive manufacturing technique employed to construct comprehensive 3-dimensional models using a variety of materials, catering to diverse applications. This study explores the fabrication of REDWOOD polylactic acid using (FDM) additive manufacturing processes. REDWOOD PLA, recognized for its biodegradability and renewable sourcing, holds promise as an eco-friendly material for 3D printing applications. The research investigates the tensile properties of REDWOOD polylactic acid (PLA) fabricated through Fused Deposition Modeling (FDM), emphasizing the impact of process variables. The parameters examined include printing speed (40, 50, and 60 mm/s), raster angle (0°, 45°, and 90°), layer thickness (0.1, 0.2, and 0.3 mm) and infill density (60%, 80%, and 100%). Through adherence to ASTM D368 standards, a total of 27 samples are produced and analyzed. The findings obtained from tests were analyzed and compared. Through systematic experimentation, it was found that specimens with printing speed of 60 mm/s, raster angle at 45°, a layer thickness of 0.1 mm, and an infill density of 80% exhibited the highest tensile strength [UTS-31.127 MPa]. Results reveal optimal printing conditions for achieving high tensile strength, providing valuable insights into the manufacturing of REDWOOD PLA via FDM. This research contributes to the advancement of sustainable additive manufacturing materials and informs future endeavors aimed at optimizing process parameters for enhanced mechanical performance.

Keywords: FDM, REDWOOD PLA, tensile strength, UTS, infill density
