1: The heater block is made of high-quality solid aluminum rather than cheap or inferior materials. It offers good thermal conductivity, corrosion resistance, and wear resistance, enhancing overall product performance and ensuring long-lasting durability. 2: High-precision CNC processing makes the interface of the heater block smoother and threads more precise, ensuring a tight connection. At the same time, it reduces wear between the heater block and other parts, effectively preventing filament leakage and improving overall printing stability and quality. 3: The silicone sock is made from high-temperature silicone and can work for a long time at 280°C. Note: If your printing temperature exceeds 280°C, please remove the silicone sock before printing. 4: Compatible with NTC 100K 3950 glass bead thermistor sensor or M3 stud thermistor, as well as MK8 nozzles.
