1. Smooth Feeding
Made of copper alloy, higher thermal conductivity ensures uniform heating of nozzle and smooth extrusion.Structural strength of layer-to -layer adhesion and priting quality are improved.

2. High Hardness and Wear Resistance It solves problem of rapid heating and continous printing of high-temperature filament with extended lifespan.

3. Smooth Extrusion
It greatly reduces the adhesion between filament and the nozzle which results in more smooth extrusion.

4. Better Compatibility and Applicability
Works with most FDM printing materials such as PLA, ABS, PETG, TPE, TPU, PC, etc and high temperature filaments such as PEEK, PEKK, PEI, PSU, PPSU, etc.

5. No Clogging
Smooth inner wall without burr, minor viscosity coefficient,reducing resistance, smooth feeding.
