AI Technical Summary
Existing multicolor 3D printers require multiple nozzle assemblies, resulting in large equipment size, high cost, and complicated maintenance.
Multiple colored guide filaments are fed into a single nozzle assembly, and multi-color printing is achieved through a control switch assembly. An electromagnetic assembly controls the connection or blockage between the material guide channel and the outlet. Combined with heater and radiator design, the equipment cost and size are reduced.
It enables multicolor printing on a single printhead assembly, reducing equipment manufacturing costs and size, while improving printing efficiency, reducing filament material waste, and extending nozzle life.
