After using this silicone heat shield, you can turn on the cooling fan at full speed, print high-temperature materials, and improve the success rate of printing.
The silicone insulation cover can make the heating block heat up to the required temperature faster, prevent the overflow of the hot end temperature, stabilize the hot end temperature and avoid the impact of the environment.
Compared with the original heat-resistant cotton that is easy to wear, the silicone insulation sleeve is more durable and effective.
