The Prusa FFF printers are equipped with a brass nozzle. Brass has excellent heat conductivity and is tough enough to print most common filaments. However, when using abrasive filaments, the brass nozzle tends to wear too quickly, so abrasion-resistant nozzles are available. 

Depending on your printer model, the hotend uses either an E3D V6 nozzle or a Prusa Nozzle. If you want to use E3D V6 nozzles on printers designed for the Prusa Nozzle system, a Nextruder V6 Nozzle Adapter is available. 

This article provides an overview of the different nozzle types used across our printers and explains how they fit into each system. For more detailed instructions, recommendations, and compatibility information, please follow the links included in each section.

Prusa Nozzle

Designed for Nextruder-based printers (CORE One, XL, MK4/S, MK3.9/S), the Prusa Nozzle is built for cold, quick swaps and maximum convenience. It is available in a range of materials and diameters. 

Check out the detailed information in the dedicated article for Prusa Nozzle types for Nextruder printers

E3D V6 nozzles

The E3D V6 (and E3D V6-compatible) nozzles are used in the MK3.5/S, MK3/S/+, MINI/+, MK2.5/S, MK2/S, and earlier models. They are a widely adopted standard, but they must be tightened while hot to ensure a proper seal and avoid filament leakage. The filament is led into the heatbreak through a PTFE tube. 

Find out all the E3D V6 nozzle types and their details in the dedicated article for E3D V6 Nozzles

Nextruder V6 Nozzle Adapter

The Nextruder V6 Nozzle Adapter enables your Prusa printer’s Nextruder to accept E3D V6 nozzles.
