E3D Online E3D High Flow ObXidian K2 Plus Nozzles

Designed for high flow and speed. At the core of the K2 Plus nozzle is E3D's unique internal multi-channel design. By splitting the filament path into four channels, the contact area is significantly increased. This allows for a higher flow rate of up to 48 mm³/s, enabling consistent extrusion even at print speeds of up to 600 mm/s. Whether you are looking for more reliability or want to push the limits of your slicer, this nozzle is optimized for modern high-speed systems.

Wear resistance with ObXidian technology. Each nozzle features a hardened steel insert with E3D's E3DLC™ coating. This provides significantly higher abrasion resistance than standard nozzles and is ideal for carbon or glass-filled filaments. The non-stick surface prevents plastic buildup and enhances long-term stability.

Reliable adhesion at high speeds. Print quality often suffers at high speeds – but not with these nozzles. They are specifically designed to maintain layer adhesion and filament quality even at high speeds, resulting in robust, precise parts.

Thermal management with four metals. A titanium heat break ensures a clear thermal separation between the cold and hot zones, reducing heat transfer and improving print stability. The four-metal construction optimizes each material according to its function.

Wide material compatibility. These nozzles support many filament types: PLA, ABS, PETG, TPU, PP, PC, PA, PLA-CF, ABS-CF, PETG-CF, PC-CF, PA-CF. For filled materials, it is advisable to check the manufacturer's data sheet – especially for 0.4 mm – as larger particles can cause clogs.
