## Summary description

Replacement MK8 nozzle for 3D printers, OEM copper construction with a 0.4 mm orifice designed for 1.75 mm filament. Provides the standard nozzle diameter for general-purpose printing, compatible with MK8-style hotends and suited for PLA, ABS and other common filaments. Used for maintenance, nozzle swaps and restoring extrusion quality.

## Long description

Replacement MK8 nozzle made of copper with a 0.4 mm orifice designed for 1.75 mm filament. This nozzle matches the MK8 form factor used on many consumer FDM 3D printers and provides the common 0.4 mm aperture suited to general-purpose printing. It is intended for routine maintenance, nozzle swaps and restoring consistent extrusion flow when changing materials or clearing clogs. The copper construction offers good thermal conductivity for stable melt conditions with standard filaments such as PLA and ABS.
Advantages
The MK8 0.4 mm copper nozzle delivers reliable dimensional accuracy for layer lines and feature details typical of a 0.4 mm aperture. Copper's thermal properties promote even heating across the nozzle tip, which helps maintain steady filament flow and reduce localized heat variation. The nozzle is compatible with MK8-style hotends and installs using standard torque practices for metal nozzles, allowing quick replacement without requiring modifications to the extruder assembly.
Suitable for
 General-purpose 3D printing with 1.75 mm filament
 Printing common materials such as PLA and ABS
 Routine maintenance and nozzle replacement
 Restoring extrusion after partial clogging or wear
Key specifications
 Nozzle type: MK8-style
 Orifice diameter: 0.4 mm
 Filament diameter compatibility: 1.75 mm
 Material: copper
 Intended use: FDM/FFF 3D printers
How to use
Allow the hotend to heat to printing temperature for the filament currently loaded before attempting nozzle removal to avoid damage. Use the appropriate wrench to hold the heater block and a second wrench to unscrew the existing nozzle; then screw in the replacement MK8 copper nozzle by hand until seated, and finish tightening with the wrench while the hotend is at working temperature to ensure a proper seal. After installation, run a temperature-specific extrusion test and calibrate retraction and flow settings if switching filament types or nozzle diameters.
Usage recommendations
For best results, match printing temperatures and retraction settings to the material in use and inspect the nozzle tip periodically for buildup. Use proper tools and safety precautions when working with a heated hotend. If frequent abrasion is expected (filled or composite filaments), consider a nozzle material designed for wear resistance.
