Features: For Metal nozzle ensures rapid heat transfer for efficient printing with ABS, PETG and more filaments, featuring engraved size markings for quick identification. Precise machined 0.4mm/0.6mm nozzle openings with threading deliver consistent extrusion accuracy, while wear resistant Metal construction minimizes clogging during prolonged printing operations. Designed for makers and professional upgrading for printers requiring durability components for high temperature filament processing. Optimize detailed miniatures or functional prototypes across home workshops and industrial labs, maintaining stable flows rates even during 12+ hour continuous printing. The anti clog design simplifies maintenance between filaments changes, while standardized threading ensures compatibility with most printer extruder assemblies.
