0.4mm Brass Nozzle for Prusa MK4S, CORE One, One L, XL

The 0.4mm brass nozzle is a high-precision all-metal nozzle specifically designed for the Nextruder of Prusa 3D printers. It combines the nozzle and heat break into a single component, simplifying the hot end assembly and significantly speeding up nozzle changes. The entire filament path through the Nextruder is made of metal, eliminating the need for PTFE tubing in the hot end. This design enhances the overall reliability of the printing system and ensures consistent filament flow. The nozzle is compatible with Prusa printer models MK4S, MK4, MK3.9, MK3.9S, CORE One, CORE One+, CORE One+ (Gen 2), CORE One L, CORE One L+, XL, and XL+. Brass, as a material, offers excellent thermal conductivity and is ideal for printing with standard filaments such as PLA, PETG, and ABS. The 0.4mm nozzle diameter represents the most common standard, providing a balanced ratio between detail precision and print speed. For users who wish to continue using V6-compatible nozzles, Prusa offers a separate Nextruder-to-V6 adapter. The nozzle is mounted with tool assistance following the official Prusa assembly instructions.

Features:

• All-metal construction combines nozzle and heat break into one component for quick changes.
• Brass material provides excellent thermal conductivity for consistent print results.
• 0.4mm nozzle diameter offers an optimal balance between detail and speed.
