Problems solved by technology

[0003] For some more complex models with suspended structures, the 3D printing process needs to print the supporting structure at the same time to realize the printing of the suspended structure, otherwise the forming process of the suspended structure cannot be realized
like figure 1 Shown is a schematic diagram of printing a model 20 on the printing platform 10. The model 20 has a suspended structure 21. The suspended structure 21 cannot be directly printed during the three-dimensional forming process. It is necessary to print out the supporting structure 22 during the forming process. Otherwise, the printing of the suspended structure cannot be realized
However, in the process of printing the support structure of the suspended structure, it needs to consume a lot of consumables and a lot of printing time at the same time

Abstract

The invention provides a three-dimensional rapid prototyping method and system. The method comprises the following steps: acquiring three-dimensional model data; based on the three-dimensional model data, a suspended structure needing to be supported is calculated, and supporting information is obtained; according to the supporting information, a supporting component corresponding to the block needing to be supported is provided on a printing platform; and a basic supporting part is formed on the supporting component, and the basic supporting part is formed by a printing material and is used for supporting the suspended structure together with the supporting component. The printing cost of the model with the suspended structure is reduced, and meanwhile the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a three-dimensional rapid prototyping method and system. Background technique [0002] Among the 3D printing technologies, the commonly used one is the fusion deposition printing technology, which can realize the printing of various three-dimensional modeling models. [0003] For some more complex models with suspended structures, the 3D printing process needs to print the supporting structure at the same time to realize the printing of the suspended structure, otherwise the forming process of the suspended structure cannot be realized. Such as figure 1 Shown is a schematic diagram of printing a model 20 on the printing platform 10. The model 20 has a suspended structure 21. The suspended structure 21 cannot be directly printed during the three-dimensional forming process. It is necessary to print out the supporting structure 22 during the forming process. Otherwise, the pr...
