Embodiment 1

[0024] A powder feeding 3D printing nozzle with a powder mixing device installed on the connecting frame A. The powder feeding 3D printing nozzle includes a nozzle body and a nozzle 400 installed at the end of the nozzle body. A plurality of powder channels and a powder mixing channel 200 are arranged inside the nozzle body, and the ends of the multiple powder channels are connected to the powder mixing channel. The middle and upper part of 200 are connected; the mixing rod 300 is suspended in the powder mixing channel 200, and the powder entering from each powder channel flows to the stirring rod 300 installed in the powder mixing channel 200; the stirring rod 300 is hollow and thin-walled structure and the thin wall of the stirring rod 300 is provided with a plurality of holes.

[0025] In this embodiment, a stirring rod 300 is installed in the powder mixing channel 200. On the one hand, the stirring rod 300 with a hollow thin-walled structure and a plurality of holes in the...

Embodiment 2

[0028] A powder feeding 3D printing nozzle with a powder mixing device, including a nozzle body and a nozzle 400 installed at the end of the nozzle body, a plurality of powder channels and a powder mixing channel 200 are arranged inside the nozzle body, and the plurality of powder channels The ends are all connected to the middle and upper part of the powder mixing channel 200; it is characterized in that: the powder mixing channel 200 is suspended with a stirring rod 300 installed, and the powder entering from each powder channel flows to the stirring rod 300 installed in the powder mixing channel 200; The stirring rod 300 is a hollow thin-walled structure, and the thin wall of the stirring rod 300 is provided with a plurality of holes.

Abstract

The invention relates to the technical field of 3D printing, and discloses a powder feeding 3D printing spray head with a powder mixing device. The powder feeding 3D printing spray head comprises a spray head body and a nozzle mounted at the tail end of the spray head bod; a plurality of powder channels and a powder mixing channel are arranged in the spray head body, and the tail ends of the plurality of powder channels are all communicated with the middle upper part of the powder mixing channel; wherein a stirring rod is suspended in the powder mixing channel, and powder entering from each powder channel flows to the stirring rod mounted in the powder mixing channel; and the stirring rod is of a hollow thin-wall structure, and a plurality of holes are arranged on the thin wall of the stirring rod. According to the powder feeding 3D printing spray head with the powder mixing device provided by the invention, the nozzle can be used for mixing various 3D printing whitewashes.

Description

technical field [0001] The invention relates to the technical field of 3D printing, specifically, a powder feeding 3D printing nozzle with a powder mixing device. Background technique [0002] In the 1980s, 3D printing technology was born. 3D printing is a bottom-up manufacturing method, also known as additive manufacturing technology, which is different from traditional "removal" processing methods. 3D printing technology has been widely concerned by people since its birth, so it has developed rapidly. In recent decades, 3D printing technology has become the focus of attention and has been applied in industrial design, architecture, automobile, aerospace, dentistry, education and other fields, but its application and development are still limited by factors. In addition to the parameters of equipment and printing procedures, the materials used for parts are also key factors affecting the quality of 3D printing products. [0003] For a long time, 3D printed parts were pri...
