Effects of Fused Deposition Modeling Process Parameters Infill Pattern, Layer Thickness, and Printing Temperature on the Tensile Properties and Surface Roughness of 3D-Printed Polylactic Acid

Key Points

• Tensile properties are influenced by variations in layer thickness, printing temperature, and infill pattern.
• A layer thickness of 0.1 mm and specific infill patterns improved tensile strength by 25% when compared to thicker layers.
• Analysis using fused deposition modeling, a common 3D printing technique, revealed significant changes in surface roughness with different parameters.
• Highlights the need for careful optimization of 3D printing settings to enhance material performance and surface quality.
