The thermal fuse for 3D printers is a key component that provides protection against overheating of the heater and the risk of fire. It reacts when a certain temperature is reached, shutting off the power to the heater to prevent damage or dangerous situations. This protects both the printer itself and the surrounding environment from potential harm. Thermal fuses can be adjusted for different temperature thresholds depending on the specific requirements of the printer and the materials used for printing.
