These nozzles are designed as a drop-in upgrade for Creality K2 Series printers, including the K2 and K2 Plus. The product description also states they are designed specifically for K2 Plus and Hi 3D printers.

No. The nozzle is described as a seamless drop-in upgrade that does not require mount or fan-duct changes.

The nozzle supports a maximum flow rate of up to 48 mm³/s and high-speed printing up to 600 mm/s. Actual results depend on the printer setup, filament, and slicer settings.

E3D uses a multi-channel internal geometry that splits the filament path into four channels. This increases the contact surface area for better heat transfer and higher volumetric flow.

Yes. The hardened steel insert and E3DLC™ coating are designed for abrasive and filled materials, including carbon fibre and glass fibre-filled filaments.

Not always. Some filled materials contain particles that are close to or larger than a 0.4 mm nozzle opening, which increases the risk of jams, so the filament manufacturer's minimum nozzle recommendation should be checked first.

The E3DLC™ coating adds non-stick properties to the nozzle surface. This helps reduce plastic build-up around the nozzle and can improve print cleanliness and surface finish.

The product description states that these nozzles maintain interlayer adhesion strength at higher speeds. That helps preserve both surface finish and part strength for functional prints.
