Abstract:
Currently, Fused Deposition Modelling (FDM) is a preferred method for 3D printing in manufacturing when compared to other techniques. The FDM methodology can be seamlessly integrated by configuring a predetermined procedure and framework to the apparatus through a data transmission mechanism. There exist multiple options for modifying the input parameters in accordance with the user's requirements. In this work, the most commonly used FDM material namely PLA and a supportive material glass fiber are used for the experiments (specimen fabrication). The experiments in this study were done to see how process parameters like layer thickness, infill%, raster angle and infill material variation PLA+5-10% glass fiber, affected their response variables which are surface roughness, tensile strength, and impact strength. Also, The Taguchi approach was utilised to optimise and determine the respective effects of the components on the response, resulting in the derivation of findings. Moreover, the ANOVA method was employed to conduct pertinent analysis and draw conclusions. Results show a uniform variation of all responses with layer thickness parameter which was found significant and the most influencing factor as well. While raster angle was found significant factor only in surface roughness response analysis. Similarly, infill% was found significant only in tensile strength response analysis. The addition of supportive material was found affirmative for mechanical property enhancement but degraded the surface quality of the fabricated specimens.
