Problems solved by technology

Generally, the material to be heated is in the form of filaments, which are guided into the heating part by the tubular guide part for heating. However, due to the uneven heating temperature in the heating part, the filament material will melt unevenly, appear lumpy, affect the effect, and even cause nozzle blockage.

Abstract

The invention provides an anti-blocking 3D printer nozzle. The anti-blocking 3D printer nozzle comprises a heating pipe, a storage chamber, a material conveying pipe and a nozzle body which communicate with one another in sequence, wherein a heating sleeve is arranged outside the heating pipe in a sleeving mode, a flow control valve is connected to the material conveying pipe, a cavity is formed in the side wall of the nozzle body, an electric heating wire is arranged in the cavity, and a spray head is arranged at the lower end of the nozzle body. According to the anti-blocking 3D printer nozzle, melting is uniform, and the spray head is not blocked.

Description

technical field [0001] The invention relates to 3D printing technology, in particular to an anti-blocking nozzle of a 3D printer. Background technique [0002] 3D printing, also known as three-dimensional printer, is a kind of rapid prototyping technology. It is a cumulative manufacturing technology. It uses high temperature heating to melt the material into a liquid state, extrudes it through the printer head, solidifies it, and finally arranges it in a three-dimensional space to form a three-dimensional object. Generally, the material to be heated is in the form of filaments, which are guided into the heating part by the tubular guide part for heating. However, due to the uneven heating temperature in the heating part, the filament material will melt unevenly, appear lumpy, affect the effect, and even cause nozzle blockage. . Contents of the invention [0003] In view of this, the present invention aims to propose an anti-clogging 3D printer nozzle that melts uniformly ...
