Frequently asked questions
What Prusa printers are compatible with this E3D High Flow 0.4mm nozzle?
Compatible with Prusa MK4, MK4S, MK3.9, MK3.9S, XL, CORE One, CORE One+, and CORE One L. Not compatible with MK3.5, MK3.5S, MK3S+, MK3, MK2.5S, MK2.5, MINI, MINI+, MMU3, SL1S, HT90, or INDX.
What is the difference between the E3D High Flow 0.4mm and the Nextruder Brass Nozzle 0.4mm standard?
The High Flow 4-channel internal geometry increases the maximum volumetric flow rate compared to the standard 0.4 mm nozzle, allowing for much higher print speeds. The outer diameter is identical — it's a direct drop-in upgrade.
Is this nozzle suitable for abrasive filaments like CF or GF?
No. For abrasive filaments, use the hardened steel nozzle, sold separately. Brass wears out quickly with materials such as PLA-CF, PETG-CF, PA-CF, or glass fibre composites.
Is it also available in 0.6 mm?
Yes. The E3D Prusa High Flow Brass Nozzle is available in 0.4 mm and 0.6 mm, sold separately. The 0.6 mm is suitable for larger and even faster prints.
