Effect of Infill Pattern Type on a 3D-Printed Component
摘要
The number of process parameters and their effects on subtractive manufacturing processes is distinguishable. During Fused Deposition Modeling-type 3D printing, many process parameters affect the printing process. One such parameter is the infill pattern, which determines the internal structure of a printed object. Infill is the fundamental characteristic influencing the mechanical properties of the product. The material consumption and build time vary with different infill patterns for the same product. In the present work, seven infill patterns have been selected to print a standard ASTM component. The material consumption, print time, surface roughness, and tensile strength for different infill patterns are measured. Tri-hexagon and zigzag infill patterns had the highest material consumption of 7 g and gyroid with a maximum time of 65 min. The lightning infill pattern has the least surface roughness of 1.34 µm. The maximum tensile strength of the concentric infill pattern is 24.34 MPa.
