This research study presents the development of the quality prototype is critical in any additive manufacturing process as it directly relates to its strength and accuracy. The process of Selective Laser Sintering (SLS) is a versatile and proven process to build quality prototypes. This paper attempts to study the influence of build factors such as part orientation, part bed temperature, and refresh rate (one time used and virgin material by percentage of volume) on the part quality. Taguchi design technique L9 (3 × 3) array settings used. Aimed at the required process factors with least number of experimental runs, the L9 orthogonal array method of experiments prepared using the analysis tools S/N ratio, and Analysis of variance, (ANOVA). The significant control factors are identified for surface roughness, which is necessary for designers and Rapid Prototype machine users. |
