The Effect of Built 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 oxidising 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 varying the print orientation (X,Y,Z) with infill density (50%,75%,100%) is done to check the nine combinations of mechanical and tribological properties like hardness, impact strength, ultimate tensile strength, flexural strength, fatigue strength, wear rate and coefficient of friction was observed. The results shows that the all the tested mechanical and tribological properties increases by around 30-60% when the orientation is in X direction and a infill density 75%. Due to the formation of anisotropic nature in the parts formed due to orientation in X direction, the orientation 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.
