Photo curing three-dimensional printer

Abstract

The photo curing 3D printer includes: a containing tank for containing a printing molding material; a molding platform arranged adjacent to the containing tank; a motor mechanically connected to the molding platform and configured to drive the molding platform to move; a position encoder configured to detect moving position of the molding platform; a driver configured to output a control signal to control the motor to drive the molding platform to move， and a controller electrically connected to the position encoder and the driver， configured to continuously receive different position signals from the position encoder， calculate a cumulative error between the positions represented by the continuous different position signals and the positions represented by the control signal， and when the cumulative error reaches a preset value， send a speed change signal to change a moving speed of the molding platform.
