AI Technical Summary
Existing 3D printers are susceptible to external interference when in an open state, which can lead to printing failures, damage to the printhead, high temperatures, burns to users, and frequent overheating of the printhead.
The protective box is designed with a protective cover, a cooler, a limiting component, and a fumigation component inside. The front of the protective box has a visible glass door. The printhead is protected and cooled by an electric telescopic rod and a lead screw slide, and toxic gases are purified by the fumigation component.
It effectively prevents workpieces from being disturbed by external factors, protects the printhead from bumps and damage, reduces printhead temperature to avoid burns, and ensures print quality and safety.
