In 3D printing, PEEK, PEKK, PEI, PSU, PPSU and other filaments that can be melted over 300℃ are called high temperature filaments. With an ordinary brass nozzle, the print cannot be completed. The thermal conductivity of the copper alloy nozzle is 330W/mk, and the maximum printing temperature can reach 500℃, which can solve the problem of rapid heating of high-temperature filament and continuous printing, and effectively extend the life of the nozzle.
