Characteristics of Process Parameters in Fused Deposition Modelling Process

Abstract

Additive manufacturing has received incredible attention as a crucial emerging technology as three-dimensional printing offers wide range of industrial applications. This article outlines empirical analyses on the influence of key process parameters such as print speed, infill speed and layer resolution on roughness of the surface and time taken of Fused Deposition Modelling (FDM) processed of Polylactic Acid (PLA) part. Influence of each parameter couple with analysis of variance were utilize using full factorial design. The optimum parameters setting for best surface roughness and lower machining time also being determined. Experimental results indicate that optimal factor settings for each performance characteristic are different.
