Abstract
The present invention relates to a method of determining layer thicknesses of a three-dimensional model for generation with an additive manufacturing apparatus. The method includes: a step of determining the layer thicknesses according to an adaptive slicing algorithm in which the thickness of a layer is calculated through a relation based on the inclination of the normal vectors of the surface elements of the 3D model partly enclose the layer from a horizontal direction (x;y).
