Effects of Infill Patterns on Time, Surface Roughness and Tensile Strength in 3D Printing

  Dhruv Maheshkumar Patel

The effects of three different infill patterns on printing time, surface roughness and tensile strength in 3D printing is investigated. 3D printing is an additive manufacturing technology to rapidly create prototypes by laying down a broad range of material onto successive layers of surfaces. Standard 3D printers use infill patterns known as grid, lines, cubic, triangles, tetrahedral, concentric and zigzag. We tested infill patterns of lines, grid and concentric at a density of 40% and 60% using a 0.6 mm nozzle. The prints were timed to allow comparison of print speeds. After printing, the printing time was checked, and the surface roughness and tensile strength was measured. The results showed that the concentric infill pattern had the fastest printing time as compared to lines and grid infill patterns. The tensile strength of the lines infill pattern was higher than the grid pattern followed by the concentric infill pattern.
