Problems solved by technology

At present, there are two commonly used support methods, one is the cross-shaped support method, and the other is the honeycomb-shaped support method. These two support methods have certain support strength for the 3D printing model, but they have their corresponding problems, such as ten The diagonal line of the glyph support is strong, but the toughness is poor, while the honeycomb support takes a long time to print, and the two support calculation methods are all the way from bottom to top. Even if the support density is increased, it cannot solve the problem of weak 3D printing. question

Abstract

The invention provides a 3D printing model inner support calculating method. The method comprises the following steps that an object three-dimensional model is guided in, and the three-dimensional model is analyzed to obtain a standard format model with the stl format; the standard format model with the stl format is analyzed, and calculating printing model parameters are obtained; a three-dimensional model file with the supporting amount to be estimated is input, and parameters of a support model are calculated and obtained; and a support structure is obtained according to the support model.The support designed by the method is based on the most stable triangle, a triangular frame is used as the support, the stronger internal structure is provided, and therefore the strength of a printing model is improved; due to the variability of the support, the defect that the transverse model strength of the 3D printing technology based on FDM is insufficient is overcome form the perspective ofangle; and under the requirements of the same strength, support printing time is greatly saved, and the stability of an upper-layer structure of the model is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a calculation method for internal support of a 3D printing model. Background technique [0002] In the field of rapid prototyping technology, 3D printing is one of the most popular technologies. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. When encountering a hollow model, it is necessary to add supports to ensure that the model can be formed in good condition. At present, there are two commonly used support methods, one is the cross-shaped support method, and the other is the honeycomb-shaped support method. These two support methods have certain support strength for the 3D printing model, but they have their corresponding problems, such as ten The diagonal line of the glyph support is strong, but the toughness is poor, while the honeycomb support takes a long ti...
