Experimental Investigation of Fused Deposition Modelling Process Parameters to Optimize the fabrication of Connecting Rod Bush
Main Article Content
Abstract
This paper describes the experimental investigation and optimisation of various parameters affecting Fused Deposition modelling (FDM) Techniques, namely orientation angle, layer thickness, and nozzle diameter, to achieve finest surface texture values on 3D printed Acrylonitrile Butadiene Styrene (ABS) used to fabricate a connecting rod bush. The printer utilised here is "Ultimaker 2+," and the filament is 2.85 mm in diameter and yellow. A Mitutoyo surface finish meter, an exceedingly accurate and precise measuring equipment, is used to determine surface finish. Taguchi's orthogonal array method is utilised to develop and conduct the experiments. The process parameters that affect the surface finish values of FDM printed models were then researched and optimised using a response table.
