AI Technical Summary
In existing 3D printing technologies, automatic material changing systems are complex in structure, difficult to troubleshoot, have unstable printing pressure, and low material changing efficiency, making it difficult to meet the printing requirements of high-precision and high-hardness composite materials.
The device employs a one-way transmission mechanism connected to the filament disk, combined with a speed monitoring device and a material feeding detection device, to ensure that the filament and the 3D printing equipment operate synchronously, simplifying the structure and improving material changing efficiency.
It features a simple structure, convenient troubleshooting, high printing stability, and strong adaptability, significantly improving material changing speed and printing accuracy.
