Easy-to-dismount 3D (Three Dimensional) printer nozzle

Abstract

The invention relates to an easy-to-dismount 3D (Three Dimensional) printer nozzle and belongs to the field of parts of a 3D printer. The easy-to-dismount 3D printer nozzle comprises a nozzle seat, a connector, a connecting sleeve, a heater and a material spraying head, which are connected in sequence and form a material conveying channel, wherein the connector is connected onto the nozzle seat; the heater is connected between the connecting sleeve and the material spraying head and is used for heating and melting a wire rod at an outlet of the material conveying channel; the connector is in clamping connection with the connecting sleeve. The nozzle seat is additionally provided with a structure can be rapidly replaced, when the nozzle has faults, the whole body of the heater can be rapidly detached and replaced, so that replacement time is saved. By adopting the structure, the heater and the spraying head are connected to form a whole body, and the heater and the spraying head can be conveniently and wholly detached, so that the wire rod for 3D printing can be pulled out from the heater in a detachment process, and a condition that a secondary accident on the 3D printing nozzle is caused by continual melting of the wire rod in the detachment process is prevented.

Description

technical field [0001] The invention relates to an easily detachable 3D printer nozzle, which belongs to the field of 3D printer parts. Background technique [0002] 3D printing technology is a type of rapid prototyping manufacturing technology that has developed rapidly in recent years. The most widely used in the field of 3D printing technology is called fusion deposition molding, that is, FDM method, which mainly transports thermoplastic polymer wires to high-temperature printing heads, melts the wires and continuously extrudes molten polymers, and precisely Under the positioning, three shapes are constructed by stacking layer by layer. In the 3D printing process, impurities are often mixed in the production or feeding process to cause nozzle blockage, or when printing high-hardness materials such as carbon fiber materials, the nozzle is worn by high-hardness particles in the material, and the printer needs to replace the nozzle frequently. Most of the existing nozzles ...

AI Technical Summary

Problems solved by technology

In the process of 3D printing, impurities are often mixed in the production or feeding process to cause nozzle blockage, or when printing high-hardness materials such as carbon fiber materials, the nozzle is worn by high-hardness particles in the material, and the printer needs to replace the nozzle frequently

Most of the existing nozzles are connected to the heating block by threads, and they are usually operated in a high-temperature environment during printing, which also increases the difficulty of replacement.

At the same time, since the nozzle is generally made of copper, this process can easily cause the thread of the nozzle to break
