The Ring Heater is a hotend, which is compatible with the E3D V6 ecosystem (M6 Thread). It has a round heater which wraps around nozzle. 

The advantages of a ring heater are:

​

• An even power density around the nozzle

• A better temperature distribution

• A more responsive temperature measurement

• A u-shaped or o-shaped part cooling fan can be located closer to the nozzle

This Ring Heater comes with a Thermistor cartridge and a blue silicone sock.
