Description

With the introduction of 3-D printing, fused deposition method (FDM) has become increasingly prevalent as a tool and method due to its high efficiency, convenience in handling various geometries, and material structure in production. This paper presents a study of FDM design/build parameters and there significance on the mechanical properties of 3-D printed materials. To gain insight into practical application, Taguchi experimental design methodology for a three-parameter (print speed, layer height and print temperature), three level (high, medium and low) study was implemented. The results showed a significant change in the mechanical properties resulting from the selection of various levels of these parameters, indicating that material properties such as strength may be manipulated with various level combination of the building parameters. Optimum levels of building parameters were further identified for achieving maximum mechanical strength of the material.
