AI Technical Summary
Existing 3D printer extruders are not compatible with various wire diameters, resulting in long material change times, low efficiency, and unstable pressure that can easily lead to material blockage and slippage.
It adopts an adjustable gap driven wheel structure, and the driving wheel and driven wheel are driven by a motor to achieve dynamic adjustment of the feeding gap, which is compatible with various wire diameter materials and prevents material blockage and slippage.
It achieves single-machine multi-wire diameter compatibility, short material change time, convenient operation, improves production efficiency, and ensures the stability and quality of the printing process.
