Problems solved by technology

[0002] In the field of 3D printing, the support method of the existing denture bracket consumes more metal powder, and the printing cost is high
Existing support design schemes usually only provide vertical support for the model, lack of horizontal tension, and are prone to horizontal deformation
At the same time, due to the complex model of the denture bracket and many fine parts, it is required that the support has sufficient quantity and strength, and at the same time, the support is required to be easy to remove
The denture support frame designed by the traditional design scheme is difficult to meet the above requirements. Therefore, in order to solve the proposed problem, it is necessary to provide a new generation method for the support of the denture support

Embodiment Construction

[0051] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0052] Such as figure 1 Shown: a support generation method for a 3D printed denture bracket, including the following steps:

[0053] S1: Import the model that needs to generate supports, project the model on the xy plane, and generate a base rod array within the plane projection range of the model, and the base rods are set vertically;

[0054] Wherein, in this embodiment, the S1 includes the following steps:

[0055] S11: Import the model that needs to generate support, read the triangular patch of the model, and generate the minimum bounding box of the model;

[0056] S12: Project the bounding box on the xy plane to obtain the model projectio...

Abstract

The invention discloses a support generation method for 3D printing for an artificial tooth support. The support generation method for 3D printing for the artificial tooth support comprises the following steps: S1, a model needing support generation is imported, the model is projected in an xy plane, a base rod array is generated in the planar projection range of the model, and base rods are vertically arranged; S2, each two adjacent base rods are connected through a cross beam, and the cross beam is horizontally arranged; S3, a part to be supported is arranged on the model, support rods are generated slantwise on the base rods and the cross beams, and the support rods provide support for the part to be supported; and S4, the dense support rods on the base rods and the cross beams are pruned. The support reduces unnecessary contact with the model to a large extent in the case of providing major support for a fine part of the model, so that the own forming effect of the model is ensured; and meanwhile, the support is convenient to remove, and the shape of the model cannot be re-influenced if the support is removed.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a support generation method for a 3D printed denture bracket. Background technique [0002] In the field of 3D printing, the support method of the existing denture bracket consumes more metal powder, and the printing cost is high. The existing support design schemes usually only provide vertical support for the model, lack of horizontal tension, and are prone to horizontal deformation. At the same time, because the model of the denture bracket is complex and there are many delicate parts, it is required that the support has sufficient quantity and strength, and at the same time, the support is required to be easy to remove. The denture support frame designed by the traditional design scheme is difficult to meet the above requirements. Therefore, in order to solve the proposed problem, it is necessary to provide a new generation method for the support of the denture support frame. Co...
