A multi-input and one-out 3D printing color mixing nozzle that can be equipped with a camera

Abstract

The invention discloses a multi-input and one-out 3D printing color mixing nozzle which can be equipped with a camera, which includes a main cavity, a stirring mechanism, a nozzle, a fan and a camera. The main cavity includes a preheating cavity, a heating cavity and a The heat preservation chamber is provided with a plurality of feeding ports on the preheating chamber, each feeding port is arranged on an outer wall of the preheating chamber and penetrates inwardly, the side wall of the heating chamber is provided with a first heater, and the side wall of the heat preservation chamber is provided with There is a second heater, the stirring mechanism includes a stirring motor, a guide rod, a mixer and a booster rod, the guide rod is fixed on the output shaft of the stirring motor, the mixer is fixed in the middle of the guide rod, and the booster rod is fixed on the guide rod The nozzle is installed at the bottom of the flow rod and the bottom of the booster rod, the fan is installed outside the main cavity and blows air to the nozzle, the camera is installed outside the main cavity and the lens faces the nozzle, so that the feeding, mixing and extrusion processes are relatively independent, improving the The uniformity of the extruded material in terms of viscosity, thickness, color, etc.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a multi-input and one-out 3D printing color mixing nozzle that can be equipped with a camera. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. It takes 3D material management software, computer 3D aided design and mathematical 3D model design as the main technical basis, and the printing materials are printed layer by layer to construct objects. According to the different molding materials and molding methods, it is divided into the following categories: light curing stereo modeling technology (SLA), fused deposition modeling technology (FDM), selective laser sintering technology (SLS), light selective melting molding technology (SLM) and so on. Among them, the most widely used are FDM and SLA technology. [0003] At present, most of the extrusion nozzles of 3D printers based on FDM technology on the market can only achieve mono...

AI Technical Summary

Problems solved by technology

At present, there are 3D printer nozzles based on the color mixing principle on the market, but because there is no special color mixing device or the color mixing device is too simple, the problem of uneven color mixing is common, and its feeding, mixing, and extrusion processes are easy to affect each other. The speed and extrusion speed are difficult to control precisely, which greatly affects the final color mixing quality
