Experimental investigations of process parameters influence on dimensional accuracy and mechanical properties of FDM manufactured parts

Abstract

For increase of industrial competitiveness and rapid market entry with new products, various additive technologies are increasingly being used today. This paper presents the experimental results of the study the impact of the Fused Deposit Modeling (FDM) process parameters on product quality using different materials. The work is primarily focused on optimizing the important process parameters for the FDM process using the new unexplored material. The making of test samples for dimensional accuracy and mechanical properties tests was carried out on two devices, Flashforge Finder and Ultimaker 3 with two different materials: standard PLA and new composite wood (polymer + wood) material. The obtained results show that new materials that can be produced from wood waste with a certain percentage of adhesives can be used, but before that, process parameters must be precisely defined in order to achieve satisfactory quality of the final products. In this way it has a positive impact on the environment, because wood is a natural and ecologically pure material (CO 2 neutral).
