Study of Compression Performance of 3D Printed ABS Products Based on Process Parameter Optimization
In order to optimize the setting of process parameters and improve the compression performance of 3D printed ABS products,the effects of layer height,filling structure and filling density on the compression performance of 3D printed ABS products were studied through single factor test and Taguchi test in this study.The results of the single factor test demonstrated that decreasing the layer height increases the compressive strength and modulus of the ABS sample.With the increase of filling density,the compressive strength and modulus of ABS sample increase.Among all kinds of filling structures,the compression strength and compression modulus of grid filling are the largest,the compression strength and compression modulus of straight filling are the second,and the compression strength and compression modulus of concentric filling are the smallest.The results of Taguchi test showed that the degree of influence of process parameters on the compressive performance of ABS samples is filling density>filling structure>layer height.The optimization process parameter combination is that the layer height is 0.1mm,mesh filling,filling density is 100％.The compression strength of 3D printed ABS products under this parameter combination is 74.63MPa,the compression modulus is 2.76GPa,and the compression performance is the best.
