3D (three dimensional) printing manufacturing method of seal

Abstract

The invention provides a 3D (three dimensional) printing manufacturing method of a seal, which can solve problems of single structural forms of traditional seals and complicated manufacture and high costs of metal seals. The 3D printing manufacturing method adopts an additive manufacturing technology for manufacturing the seal and includes that firstly, computer 3D modeling is performed on a whole structure of the seal; then, a computer 3D model is divided into a series of two dimensional graphics in the direction of a Z axis according an equal layer thickness, and a corresponding laser scanning path is generated according to the two dimensional graphics; material powder laid on the surface of a processing platform of an additive manufacturing device in advance is scanned by high-energy laser or electronic beams according to the laser scanning path and consolidated on the surface of the processing platform after the material powder is scanned to be melted; after a layer of pattern is melted on the surface of the processing form, a layer of material powder is laid on the surface of the processing platform, and the material powder is scanned by laser till the seal is integrally formed; and then, the seal melted on the processing platform and the processing platform are moved out from the additive manufacturing device, and the seal is separated from the surface of the processing platform.

Description

technical field [0001] The invention relates to the technical field of stamp processing, in particular to a 3D printing manufacturing method for stamps. Background technique [0002] Seals, as one of the traditional art representatives of the Chinese nation, have been passed down for thousands of years. Traditional seals are mostly processed from base materials by cutting, engraving and other methods. It belongs to "subtractive manufacturing". The base materials are mainly traditional stone, Materials such as pottery (clay), wood, and resins and other polymer materials that appeared in modern times, traditional stamps processed by subtractive manufacturing methods have a single structure, while metal materials such as copper, gold, silver and other materials are used as the base. The production of seals made of materials is mostly done by machining or casting. Although it can enrich the structural form of the seals, the production process is cumbersome and the production cos...
