Abstract

Fused deposition modeling (FDM) is one of the most used additive manufacturing techniques for polymer components. The polymer materials generally used in FDM process are polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol (PETG), Nylon, etc. The mechanical properties of parts fabricated by FDM depend on material and process parameters. Several researchers have tried to investigate the influence of process parameters on mechanical properties for some of the materials. So, those parameters can be taken care of for better properties during fabrication of parts. In this paper, effects of layer thickness, raster angle, infill density and printing speed on mechanical properties have been investigated and comparative analysis has been carried out for PETG and nylon specimens. The result showed that nylon and PETG materials are suitable for application related to flexibility and high tensile strength, respectively.
