This hotend sock will greatly help to stabalize the temperature of the hotend regardless of the surrounding environment temperatures. Hotend Socks can be used to quickly heat the hotend to a desired temperature as the structure of the silicone inside the sock prevents heat from escaping quickly. This is a great replacement for the ely worn and torn kapton tape and heat resistant cotton that come with most 3D printers. This silicone sock is much more durable and functional when compared to typical stock soloutions for hotend insulation. With this sock you can safely print more exotic materials such as PETG at higher temperatures while also using the cooling fans at full speed. Actively keeping the hotend very hot and cooling the PETG much quicker before it is laid onto the hotbed can help with success rates on more prints.
