Article: Optimisation for geometrical dimension of a product using 3D printer based on fused deposition modelling Journal: International Journal of Additive and Subtractive Materials Manufacturing (IJASMM) 2017 Vol.1 No.2 pp.133 - 144 Abstract: The product development and the modification of the existing product are fundamental aspects of innovation and competitiveness of organisations, supported by concurrent engineering approaches. In the present work, an attempt has been made to establish a set of the process parameters for fused deposition modelling type rapid prototyping machine using Taguchi method (L8 orthogonal array) to gain better geometrical dimensions of products. The product, viz., rapid prototyping machine, thus manufactured was used as a pattern for casting. Literature review, brainstorming sessions, cause and effect diagrams, and pilot experiments demonstrated that geometrical dimensions are influenced by four major input parameters, namely, shrinkage allowance, Acrylonitrile Butadiene Styrene (ABS) temperature at nozzle, raster angle, and bed temperature. Taguchi method was utilised to study and analyse the influence of input parameters on geometric dimensions. Further, Taguchi method was used to optimise the level of process parameters of rapid prototyping three-dimensional (3D) printers. The confirmation experiments are conducted by using the rapid prototyping 3D printer, for the determined optimum process parameter set helped to obtain the desired geometrical dimensions of patterns meant for casting applications.

Abstract: The product development and the modification of the existing product are fundamental aspects of innovation and competitiveness of organisations, supported by concurrent engineering approaches. In the present work, an attempt has been made to establish a set of the process parameters for fused deposition modelling type rapid prototyping machine using Taguchi method (L8 orthogonal array) to gain better geometrical dimensions of products. The product, viz., rapid prototyping machine, thus manufactured was used as a pattern for casting. Literature review, brainstorming sessions, cause and effect diagrams, and pilot experiments demonstrated that geometrical dimensions are influenced by four major input parameters, namely, shrinkage allowance, Acrylonitrile Butadiene Styrene (ABS) temperature at nozzle, raster angle, and bed temperature. Taguchi method was utilised to study and analyse the influence of input parameters on geometric dimensions. Further, Taguchi method was used to optimise the level of process parameters of rapid prototyping three-dimensional (3D) printers. The confirmation experiments are conducted by using the rapid prototyping 3D printer, for the determined optimum process parameter set helped to obtain the desired geometrical dimensions of patterns meant for casting applications.
