Abstract

A 3D printing nozzle device comprises a nozzle body, a first connecting piece, a second connecting piece, a third connecting piece and a pressing assembly. The nozzle body comprises a storage part, a conveying part, a spiral conveying shaft, a fixing part, a spray head and a feeding hose. A first heating part is arranged on the storage part, and a storage cavity is arranged inside the storage part. The feeding hose is arranged on the storage part and communicates with the storage cavity. The conveying part is arranged on the storage part, and provided with a conveying hole through which raw materials pass. A second heating part is arranged on the conveying part, and the spiral conveying shaft is arranged on the conveying part and located in the conveying cavity. The invention further provides a 3D printing method. Operation is easy and convenient, the protection effect is good, the service life of the nozzle is obviously prolonged, the direction and the angle of the nozzle are conveniently adjusted, the 3D printing efficiency and printing effect are improved, printing operation saves time and labor, printing raw materials can be always in a melting state, and the adverse influence on the printing process caused by solidification of the printing raw materials is avoided.

Description

technical field [0001] The invention relates to the technical field of 3D printing nozzles, in particular to a 3D printing nozzle device and a printing method. Background technique [0002] 3D printing is a kind of rapid prototyping technology.
