The Effect of Print Orientation and Infill Density for 3D Printing on Mechanical and Tribological Properties 2020-28-0411

The 3D Printing (3DP) technology due to its greatest strength, resistance to wear and corrosion to oxidizing agents and has good temperature resistance with durable one. The present article describes the effect of print orientation and infill density of 3DP route on mechanical and tribological properties of PETG filament. The 3DP parameters like layer thickness, slicing, speed, feed are kept as constant and by varying the print orientation (X, Y, Z) with infill density (50%, 75%, 100%) was printed to check the effect of it on mechanical and tribological properties like hardness, impact strength, ultimate tensile strength, flexural strength, wear rate and coefficient of friction. The results shows that all the tested mechanical and tribological properties increase by around 30-60% when the orientation is in the X direction at infill density of 100%. Due to the formation of anisotropic nature in the parts built in X direction shows more desirable results in both mechanical and tribological properties. This influenced 3DP parameters would be a right choice useful data base set by using PETG filament in various application parts with higher properties.
