The invention relates to an industrial additive manufacturing method and device based on light-cured resin. According to the industrial additive manufacturing method, a printing head is partially or completely immersed below the liquid level of a resin pool with a fixed position, the printing head is driven by a driving system to do translation and/or rotation and/or lifting motion, and a workpiece is exposed and printed in the resin pool. A traditional manufacturing mode that a printing head does not move but a workpiece in a resin pool moves is changed, the mode that the workpiece does not move and the printing head carries out additive manufacturing according to a three-dimensional model is adopted, in this way, the workpiece is directly manufactured in the resin pool and is not limited by a workpiece bearing platform any more, and therefore the working efficiency of additive manufacturing is improved. 本发明涉及一种基于光固化树脂的工业化增材制造方法和装置。工业化增材制造方法打印头部分或全部沉浸在位置固定的树脂池液面下方，并在驱动系统的带动下，打印头做平移和/或旋转和/或升降运动，而在树脂池中曝光打印工件。本
