The Influence of Process Parameters on the Surface Roughness of the 3d Printed Part in FDM Process

Abstract

3D printing is a promising digital manufacturing technique that produces parts with layer by layer. The influence of process parameters is investigated for ABS material in fused deposition modelling (FDM). This work aimed to determine the surface roughness of 3d printed parts of the ABS material with varied parameters of infill height and infill density. The results of the test show that the, surface roughness is higher (11.6mm) at 20% infill density with 0.26mm infill layer height. Also, ABS material surface shows good finish (lower surface roughness) at 100% infill density with 0.06mm infill layer height. The infill layer height clearly visible under microscope at higher infill layer height with all the infill densities.
