Description 244-251
Fused deposition modeling (FDM) is a 3D printing technique that prints thermoplastic layer by layer. Various parameters affect the properties of the final printed object. The exact identification of variation in the properties of the printed object is still a very popular issue among the researchers. In the present work, an effort has been made to identify the parametric influence of layer thickness, infill density, print speed and extruder temperature on the wear behavior of the printed specimens. The specimens of polylactic acid (PLA) have been printed using Fused Deposition Modeling (FDM). The combinations of input parameters during the fabrication have been considered as per the Taguchi L16 Orthogonal Array. Moreover, to identify the parametric influence on wear, mathematical modeling has been done using regression and artificial neural networks. The results show that the average percentage variation in predicted experimental values for regression and ANN models are, 5.04% and 1.94%, respectively. Moreover, for minimum wear layer thickness should be kept between 0.28- 0.34mm. Similarly, infill density, print speed, and extruder temperature should be between 70-72, 125-175mm/s and 195-202 degree, respectively.
