B33Y 50/02 - Data acquisition or data processing for additive manufacturing for controlling or regulating additive manufacturing processes
Disclosed in the present invention are a method and apparatus for automatically improving printing effect, a device, and a storage medium. The method comprises: receiving an import request of a 3D model, and parsing a triangle patch comprised in the 3D model; acquiring all angular points of the 3D model according to the triangle patch, subtracting a minimum angular point from a maximum angular point to obtain a bounding box of the 3D model, creating an axis perpendicular to the bounding box; using the axis and a platform inclination angle to calculate a quaternion related to the rotation of the 3D model; multiplying a space matrix of the bounding box of the 3D model by the rotation matrix, enabling a printing path to be perpendicular to the bounding box. The model is imported to automatically keep the inclination angle consistent with a platform, thereby improving the printing effect.
