The study of factors affecting mechanical properties of 3D printing with 6-axis robotic arm

Abstract

The objective of this research is to study the fabrication of 3D printing system with a six-axis robot arm with an ABS plastic fiber feeding system controlled with a programmable logic controller. The study has been studied the variables affecting the mechanical properties of the percentage adhesion of printed plastics by using the Taguchi experimental design method with the L9 (3³) orthogonal array and three control factors with 3 levels: 180, 190, 200 pulse signal, and 0.9, 1.0, 1.1 mm plastic fiber spacing and fiber melting temperature 190, 200, 210 degrees Celsius. The proposed approach of the study confirmed that the optimal factor results based on the highest mean of signal to-noise ratio (S/N) ratio level are 200 pulses and 0.9 mm plastic fiber spacing, and heat for plastic fiber melting 210 °C, and the most elongated percentage at 3.422%.
