【摘要】 为协调3D打印的精度和效率，提出了1种区域自适应分层方法.将每层分为内外2个区域，以对外部自适应层厚得到所需的表面精度，以初始层厚成型内部区域缩减成型时间，并采用有限细分的自适应策略避免了结合强度问题.实验结果表明，与传统的自适应方式相比，区域自适应在同一精度要求下显著提高成型效率.更多还原

【Abstract】 A region-based adaptive slicing algorithm was proposed in order to coordinate the accuracy and efficiency in 3D printing. The layer was divided into internal and external region. The required surface accuracy was obtained through the thickness of adaptive slice external layer, while the molding time was reduced using initial layer thickness. A finite subdivision adaptive strategy was adopted to avoid the strength issue. The printing results show that the adaptive based on region partition can significantly shorten the molding time while ensuring surface accuracy.更多还原
