Double-nozzle extrusion type ceramic 3D printer and printing method thereof

Abstract

The invention provides a double-nozzle extrusion type ceramic 3D printer and a printing method thereof. The ceramic 3D printer of the invention adopts a fine printing nozzle and a coarse printing nozzle to cooperate for printing. If an entity of the same shape and size is printed, the printing time is short compared with adoption of the fine printing nozzle only, and the printing precision is highcompared with adoption of the coarse printing nozzle only. The ceramic materials used in the ceramic 3D printer of the present invention have different masses and different costs, the cost of the refined ceramic material is high, and the cost of the coarse ceramic material is low, that is, the outer surface texture of a formed entity is not influenced compared with adoption of the refined ceramicmaterial only, and the total cost is reduced. The ceramic 3D printer of the invention has the advantages of simple structure, convenient operation, greatly reduced production and use cost, and can bewidely applied. The printing method of the ceramic 3D printer of the invention has the advantages of simple principle and high feasibility.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a ceramic 3D printer and a printing method thereof. Background technique [0002] Ceramics are made of various natural minerals as main raw materials through crushing, kneading, molding and calcination. Traditional ceramic preparation technology can only produce products with simple shapes. Ceramic 3D printing technology makes it possible to prepare complex ceramic products. Compared with traditional manufacturing methods, ceramic 3D printing has the following advantages: First, no mold is required, the development cycle is short, and time and cost are saved ; Second, it can realize the molding of complex shape structural parts, breaking through the shape limitation of traditional ceramic processing technology. [0003] There are many existing ceramic 3D printing technologies, among which extrusion printing technology is the earliest and more mature technology. ...

AI Technical Summary

Problems solved by technology

That is, the nozzle diameter is small, the nozzle stroke is long, the printing time is long, but the printing accuracy is high; the nozzle diameter is large, the nozzle stroke is small, the printing time is short, but the printing accuracy is low

The problem of printing efficiency restricts the production and application of extruded ceramic 3D printing technology, and the problem of printing accuracy restricts the popularization and promotion of extruded ceramic 3D printing technology
