Abstract:

Insufficient instability and consumables in the existing support structure generation algorithm, an improved method of automatic generation of tree support structure is proposed. Firstly, the topology reconstruction of the STL file, the adjacency relationship between triangular patches is established. Then the points to be supported are obtained based on the equidistant sampling method. The nodes of each layer of the tree support structure are obtained through the calculation of the support cone corresponding to the support points, and finally the tree support structure is automatically generated. In addition, the end diameter of the support structure is also adjusted to increase the stability and ease of stripping of the support structure. The experimental results show that the method of this paper can effectively reduce the material consumption and support body who is more easily peeled off under the premise of ensuring the printing stability.
