EFFECT OF FABRICATION PARAMETERS AND MATERIAL FEATURES ON DIMENSIONAL ACCURACY OF FDM BUILD PARTS
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
This paper presents experimental investigations on influence of fabrication parameters viz., layer resolution, processing quality, fill mode and the processing material on dimensional accuracy of fused deposition modelling (FDM). The test specimen is designed and the levels of each factor are setup. Then Taguchi’s parameter design is applied to find optimum parameters setting to minimize percentage change in direction of X, Y and Z of test specimen. As the percentages changes are obtained, the signal to noise ratio is defined to evaluate the influence and variation. Then main effect plot is drawn to find optimal level of fabrication parameters. The results indicate that optimal factor settings for each performance characteristic are different. Therefore, analysis of variance is performed to calculate the significance level of experiment factors affecting to the dimensional accuracy in each direction. Finally, the effect of fabrication parameters and material features on dimensional accuracy of FDM build parts is obtained
