Adaptive layering type additive manufacturing method

The invention belongs to the field of additive manufacturing and discloses an adaptive layering type additive manufacturing method. The method comprises the following steps that (a), primary slicing treatment is conducted on a to-be-treated model file, and multiple main slice layers and the profile loop and data of each main slice layer are obtained; (b), points on the main slice layer profile loops are divided into difference feature vertexes and public feature vertexes; (C), local regionalization treatment is conducted on the difference feature vertexes, new local regions are generated, secondary slicing treatment is conducted on the new local regions according to the preset minimum layer thickness, and multiple sub-slice layers and profile data of the sub-slice layers are generated; and(d), 3D printing is conducted according to the profile data of the main slice layers and the sub-slice layers, and in this way, additive manufacturing is completed. By means of the adaptive layeringtype additive manufacturin
