Has an outer geometry optimized for surfaces. This is a brass nozzle (excellent temperature properties) with a hard coating of a slippery “ICE” coating. This coating prevents hot plastic sticking to it! A super nozzle!
If you heat it to more than 275C, it destroys this function and the nozzle acts like a “normal” nozzle.
IMPORTANT: This ICE nozzle looke like a (dark) steel nozzle, but it is a brass nozzle! This means it prints just like a standard brass nozzles (several times faster than steel nozzles). Fits UM2- UM2+, Olsson Block, Matchless V3
