Problems solved by technology

However, the above method is not suitable for objects with thin shell structures.
Since the inner and outer surfaces of the thin-shelled object are visible, adding support will affect the appearance and shape, and it is difficult to meet the user's design requirements

Embodiment Construction

[0071] Such as figure 1 As shown, a method for optimizing the thickness parameters of thin shell 3D printing includes the following three steps, 1. According to the geometric structure of the 3D mesh model that needs to be 3D printed, determine the maximum thickness that can be achieved at each vertex position; 2. According to The geometric structure of the model, slice the model to get the slice area, expand the intersection of the area boundaries to get the transition area, use a thickness parameter for each independent slice in the slice area, and for each vertex in the transition area Adopt a thickness parameter; 3. According to the use requirements that the model needs to meet, the external force and the materials used for printing, use specific finite element model simulation and sensitivity analysis technology, and use alternate iteration technology to optimize each grid model. The thickness a vertex needs to reach and generate a closed 3D model.

Abstract

The invention discloses a thin shell 3D printing optimization method, which includes the following three steps: 1. Determine the maximum thickness that can be achieved at each vertex position; 2. Perform slice operation on the model, and expand the intersection of area boundaries to obtain In the transition area, a thickness parameter is used for each independent sheet and each vertex; 3. According to the requirements, the thickness parameter is optimized to obtain the optimized 3D model. The method framework proposed in this paper can quickly and automatically calculate 3D printable models with sufficient structural strength and less material usage in specific usage scenarios. The method is clear, the speed is fast, and the result is robust. It can be used in computer-aided design, generating 3D printing models and other fields.

Description

technical field [0001] The invention relates to the field of computer graphics and aided design, and the field of 3D printing technology, in particular to a method for obtaining a printable entity by optimizing thickness parameters of thin shell 3D printing. Background technique [0002] 3D printing (three-dimensional printing) is a common name for additive manufacturing technology (AM, additive Manufacturing). Through digital design models, powder materials (plastic or metal) are used, and three-dimensional entities are generated by superposition molding through hot-melt bonding technology. Intelligent digital technology plays an important role in the 3D printing process. With the help of computer implementation, the user's intention can be realized perfectly and a printable entity can be generated. With the continuous development of technology, 3D printers can use a variety of materials, including powder, material, metal, etc., as well as chocolate, human stem cells, etc....
