Study on the Effect of Fused Deposition Modeling (FDM) Process Parameters on the Printed Part Quality

3D printing known as additive manufacturing (AM) has been applied for applications in different fields such as aerospace, automotive, biomedical, and energy industries. It is the fact that 3D printing has gained a very wide acceptance over the last decade. However, several significant hurdles prevent its wider adoption. One of the most important barriers is the quality of the printed parts. Currently, many manufacturers and end users have difficulty stating with certainty that parts or products produced via 3D printing will be of consistent quality, strength, and reliability. Without this guarantee, many manufacturers will remain leery of AM technology. For getting the good quality of the printed part, influence factors must be considered such as material properties, machine specifications, printing conditions and process parameters. Among the large number of 3D printing methods, fused deposition modeling (FDM) method is used widely for printing the plastic products. The paper presents the analysis of the influence factors during FDM process reported in the literature as well as technology handbook to drive out the appropriate values of the printing process parameters. Experimental results were carried out with the optimal values of printing process in the 3D-FDM printer.
