Effects of Process Parameters on Surface Roughness, Dimensional Accuracy and Printing Time in 3D Printing

Abstract

In this study, the interaction of different process parameters on printing time, surface roughness and dimensional accuracy of a 3D printed object are investigated. The impact of different parameters on the performance of the 3D printer is also investigated and their optimal values have been identified. From the study, it was found that layer height, infilled density and printing speed are major influential factors affecting the surface roughness, printing time and dimensional accuracy of the 3D printed piece.
