Abstract
A large number of manufacturing companies are pursuing to additive
manufacturing technology, since this technology is absolutely amazing for
customized product. As additive manufacturing becomes widely adopted for
modeling, prototyping, rapid tooling and short-run applications, the quality control
become crucial to be developed in manufacturing business.
The intent of this study is to discuss the response quality characteristics
control of additive manufacturing technology which subject to critical printing
parameters optimization. Fused deposition modelling (FDM) is one of commonly
adopted 3D printing system in manufacturing industries.
For FDM 3D printing process, layer thickness, infill pattern, extrusion
temperature and print speed are the critical printing parameter considered for
optimization. Five response to be considered for printing parameters studies, which
is ultimate tensile strength, compressive modulus, surface roughness, dimensional
accuracy and manufacturing time.
Taguchi L9 orthogonal array method is designed for optimization of printing
parameters to achieve best quality characteristics of printed parts. Optimum
parameters values and effectiveness of printing parameters were analysed using
signal to noise ratio (S/N ratio) and analysis of variance (ANOVA). Verification
experiment were be conducted to discuss the printing performance of optimum
conditions.
