AI Technical Summary
Existing additive printers are prone to malfunctions when switching printheads, especially when printing materials with high elasticity such as TPU, resulting in unstable printing.
The wire limiting mechanism abuts against the current wire of the target nozzle to limit retraction. The control switching mechanism works in conjunction with the extrusion mechanism to loosen the clamping mechanism and release the abutment of the limiting mechanism before clamping the wire again. This ensures stable control of the wire limiting mechanism and prevents the wire from retracting into the throat and causing a blockage.
This ensures the stability of the filament during printhead switching, preventing printhead clogging and improving printing stability and reliability.
