Method and system for determining exposure interval time of 3D printing

The embodiment of the invention discloses a method for determining exposure interval time of 3D printing. The method comprises the following steps of acquiring at least one first pattern of a first slice; obtaining feature parameters of the first slice, wherein the feature parameters reflect shape information of the first pattern, size information of the first pattern and/or pattern arrangement information of the first slice; and based on the characteristic parameters of the first slice, determining the exposure interval time after printing of the first slice is completed through an exposure interval time determining model. 本申请实施例公开了一种3D打印曝光间隔时间确定方法。所述方法包括：获取第一切片的至少一个第一图案；获取所述第一切片的特征参数，所述特征参数反映所述第一图案的形状信息、所述第一图案的尺寸信息和/或所述第一切片的图案排列信息；基于所述第一切片的特征参数，利用曝光间隔时间确定模型确定所述第一切片打印完成后的曝光间隔时间。
