Abstract

Based on the closed-loop control theory in the paper, an intelligent control method of additive manufacturing based on the measurement of the line width is studied. The setpoint with the current line width which is scanned by the CCD sensor is compared, the relative relationship between the displacement speed of the forming equipments workbench and the rate of flow of the nozzle could be controlled. The Results of the study shows intelligent control of solid model and scaffoldss accuracy, pores shape and porosity, the forming precision is improved greatly makes the cell differentiation, attachment and crawling easy.
