3d printer

Abstract

A 3D printer comprises a rack which is provided with a base. The base is provided with a printing bottom plate. Stand columns are arranged on the two sides of the base. A printing platform is arranged on the stand columns. The base is further provided with a Z-axis moving system which is connected with the printing platform. Under the effect of the Z-axis moving system, the printing platform can move relative to the stand columns. A pulley block is arranged between the printing platform and the rack. An X-axis moving system and a Y-axis moving system are arranged on the surface of the printing platform. The Y-axis moving system is fixed to the printing platform. The X-axis moving system is arranged on the Y-axis moving system and can slide relative to the Y-axis moving system. The X-axis moving system is provided with a sprayer mounting pedestal which can horizontally slide relative to the X-axis moving system. A printing sprayer is arranged on the sprayer mounting pedestal. The sprayer mounting pedestal is detachably connected with the printing sprayer. The 3D printer has the advantages of being high in stability, long in service life, low in maintenance cost and the like, and the consumption requirement of the current market for the 3D printer is met.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as special wax, powdered metal or plastic, to construct objects by layer-by-layer printing. It is often used in mold manufacturing, industrial design and other fields to make models or for direct manufacturing of some products, which means that this technology is becoming popular. The working principle of a 3D printer is basically the same as that of an ordinary printer. It is to superimpose "printing materials" layer by layer through computer control, and finally turn the blueprint on the computer into a real object. [0003] The 3D printers popularized on the market generally have the following three defects, which affect the printing effect of the printer. [0004] 1. Most of the nozzles of 3D prin...

AI Technical Summary

Problems solved by technology

However, the nozzle of this structure has many parts and is inconvenient to install, which makes the production cost larger, and the parts of the nozzle of this 3D printer are large in size, which makes the overall volume larger and affects the overall appearance of the printer; The heat insulation effect of the nozzle of the 3D printer is unstable. After heating for a long time, the heat will slowly transfer to the feed pipe, and the printing material will start to soften at the upper part, resulting in clogging, which not only causes waste of printing materials, but also reduces printing efficiency and causes printing problems. loss of time

[0005] 2. The printers currently on the market generally fix the nozzles on the base of the printer by screws. The production and installation of this installation and fixing mechanism require high precision and operation requirements, which increases the production cost of the printer and reduces the cost of the printer. production efficiency; the nozzle is one of the most problematic and faulty parts in the printer, and the maintenance and replacement of this installation and fixing method requires professional tools to disassemble and install, and the operation is difficult. If it is not operated properly, it may even cause the printer to The failure of other components increases the cost of after-sales maintenance of the printer; at present, the printer has entered the homes of ordinary people, and the maintenance cost and difficulty of repairing the printer with this connection method are relatively high, which hinders the promotion of the printer in the market

(1) Although the structure of the scheme is simple, the lifting motion of the printing platform with this structure is very unstable. When a small force from the outside can make the printing platform move, it will affect the printing effect of the printer at best; and this The four-way lifting movement of the printing platform of this structure lags behind, making the printing error larger

(2) Although the transmission of the printing platform structure of the scheme is stable, this structure adds a motor and a driver, which greatly increases the cost and energy consumption, and also increases the complexity of printer installation and debugging, and increases the cost of after-sales maintenance. cost
