Genuine Original Prusa XL / MK4 / CoreOne Complete Nozzles by E3D

Prusa MK4 and XL users know that nozzle wear and slow changeovers can limit print speed and quality, especially when experimenting with different materials or nozzle sizes. Without reliable nozzles designed for the Nextruder, print consistency and efficiency suffer.

These Genuine Original E3D nozzles are engineered specifically for Prusa’s latest Nextruder system, compatible exclusively with the MK4 and XL models. Featuring an all-metal filament guide, they ensure a fully metal filament path that enhances reliability and allows faster nozzle swaps. Each nozzle size is laser-engraved for easy identification, supporting quick changes during multi-material or multi-resolution prints. The high-flow brass design improves volumetric flow rate, enabling faster printing without sacrificing quality.

Why Upgrade?

• Prusa MK4 and XL users benefit from faster nozzle changes thanks to the all-metal filament guide and engraved size markings.
• High-flow brass nozzles increase volumetric flow rate, enabling quicker prints without compromising detail.
• Improved filament path reliability reduces clogs and print failures common with stock nozzles.
• Supports a wide range of filaments up to 300°C, ideal for PLA, PETG, and ABS printing.
• Essential for users experimenting with multiple nozzle sizes or materials on the Nextruder system.

Best For:

• Prusa MK4 and XL owners upgrading their Nextruder nozzle system for better print speed and reliability.
• Users requiring quick nozzle swaps during multi-material or multi-resolution prints.
• 3D printing enthusiasts focused on high-quality prints with consistent extrusion.
• Those printing with standard and high-flow brass nozzles for improved volumetric throughput.
• Prusa community members seeking genuine E3D parts optimized for their printers.

Pair With the Right Filament

These nozzles support a broad range of filaments, making them ideal for users who want to optimize print speed and quality across common materials.

• PLA Filament — perfect for detailed prints with standard temperature requirements.
• PETG Filament — benefits from the reliable filament path and higher flow rate.
• ABS Filament — supported by the 300°C max temperature for durable parts.
