Comparison of 3D Printed Gear's Geometrical Characteristics

Abstract

A study of the influence of extruded material type and layer thickness on the surface roughness and the geometry accuracy on a 3D printed gear tooth profile is presented in this paper. A whole set of samples with the same geometric characteristics is printed from two types of materials (PLA and ABS plastic) and with different layer thickness: 0.1; 0.2; and 0.3 mm. The results of roughness testing and uniformity of the layer thickness are presented in this paper. By comparing the results of samples testing from PLA and ABS plastics with the same 3D printing parameters, a certain conclusions are presented at the end of the paper.
