Zusammenfassung:Techniques are described for improving dimensional accuracy, and more specifically z-axis or vertical dimensional accuracy in generating a 3 dimensional (3D) object comprising a plurality of formablelayers. In one example, a height configuration parameter, (such as a selected layer height, a print resolution, one or more tolerance values for certain layers or portions of a 3D object to be printed, etc.,) and a total object height, may be obtained. A first height corresponding to a subset of the plurality of formable layers may be selected based on the received height configuration parameter and the total object height. In some aspects, the first height may include a global layer height for the 3D object. The first height may be selected to optimize accuracy of the height configuration parameter or the total object height. 描述了用于改进尺寸精度的技术,且更具体地用于在生成包括多个可成型层的3维(3D)对象时改进z轴或垂直尺寸精度。在个示例中,可获得高度配置参数(诸如所选择的层高、打印分辨率、要打印的3D对象的某些层或部分的个或多个容限值,等等)和总对象高度。可基于所接收到的高度配置参数和总对象高度来选择对应于该多个可成型层的子集的第高度。在些方面,第高度可包括3D对象的全局层高。第高度可被选择成
