Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] As shown in the figure, the support structure for dental additive manufacturing disclosed by the present invention includes a tree-shaped support part 1 at the upper part and a sheet mesh support part 2 at the lower part; The trunk 11 connected by the grid support part 2 and the branches 12 located on the trunk 11; the sheet grid support part 2 is a grid-like structure composed of sheets.

[0026] In this support structure, the branches 12 of the tree-shaped support part 1 on the upper part are in contact with the molded part to support the hanging surface 3 of the molded part. The trunk 11 mainly plays the role of supporting the branches 12. It is a grid-like structure composed of flakes, which greatly saves the amount of powder used in additive manufacturing while ensuring the support strength. Under the condition of comprehensively considering its performanc...

Abstract

The invention relates to the field of prosthodontics and discloses a supporting structure for manufacturing a dental department additional material. The supporting structure comprises a tree-shaped supporting part and a slice grid supporting part which are respectively located at the upper and lower parts, wherein the tree-shaped supporting part comprises trunks and branches, the trunks are connected with the slice grid supporting part, and the branches are located on the trunks; and the slice grid supporting part is a grid structure formed by slices. The supporting structure has the advantages that (1) the supporting strength can be well guaranteed by virtue of the grid structure; (2) tree-shaped thin rods are arranged at the upper supporting part and can be conveniently removed in the subsequent period; (3) the lower supporting part is of a stepwise grid shape, so that the use amount of powder is reduced to a certain extent; and (4) the slice grid-shaped supporting structure is particularly suitable for parts which are very high in refine degree and have multiple free curved surfaces.

Description

technical field [0001] The invention relates to the field of oral restoration, in particular to a support structure for dental additive manufacturing. Background technique [0002] Restoration of the oral cavity is mainly aimed at the treatment of tooth defects and missing teeth, using artificial dental restorations. Among them, the quality of dental restoration parts plays an extremely critical role in the effect of oral restoration. Traditional dental restorations are usually manufactured by casting and cutting processes. However, with the improvement of living standards, oral restoration parts produced by casting and cutting processes have been difficult to meet the increasing requirements of patients. [0003] 3D printing is another name for additive manufacturing. It can form parts with complex shapes, high forming precision, and save materials. It can complete the manufacturing of any shape, making the whole manufacturing process truly intelligent and digital. In th...
