E3D High Flow ObXidian K2/ K2 Plus/ Hi Combo Nozzles

These premium K2/ K2 Plus/ Hi combo high-flow nozzles are the result of an official collaboration between E3D and Creality and are specifically designed for K2 Plus and Hi 3D printers. With advanced thermal properties, rapid replacement, and exceptional durability, they are ideal for fast and efficient 3D printing. Developed for both precision and efficiency, the nozzles provide excellent layer adhesion and support a wide range of filaments, including abrasive types.

Key features

• Integrated metal nozzle and HeatBreak for optimal thermal management
• Quick-change design – under 5 minutes
• High-flow geometry provides up to 48 mm³/s
• ObXidian coating for extreme wear resistance
• Maintains good layer adhesion at high speeds
• Supports many types of standard and abrasive filaments

Designed for high flow and speed

At the core of the K2 Plus nozzle is E3D’s unique multi-channel internal design. By dividing the filament path into four separate channels, the contact surface is significantly increased. This results in a higher volumetric flow rate – up to 48 mm³/s – and ensures consistent extrusion at printing speeds up to 600 mm/s. Whether you want more reliable performance or want to push your slicer settings to the limit, these nozzles are optimized for modern high-speed systems.

Wear resistance with ObXidian technology

Each nozzle features a hardened steel core coated with E3D’s E3DLC™. This technology provides wear resistance far exceeding standard nozzles and is ideal for carbon fiber and glass-filled filaments. The non-stick coating minimizes plastic buildup and improves reliability over time.

Strong adhesion at high speed

High-speed printing often compromises quality – but not here. These nozzles are designed to maintain layer adhesion and a clean finish even at higher speeds, resulting in strong and accurate functional parts.

Thermal management with four metals

A titanium HeatBreak ensures a sharp thermal transition between the cold and hot zones, minimizing heat creep and improving print stability. The quad-metallic structure optimizes each material layer according to its function.

Broad material compatibility

The nozzles support many types of filament:
PLA, ABS, PETG, TPU, PP, PC, PA, PLA-CF, ABS-CF, PETG-CF, PC-CF, PA-CF.
When using filled materials – especially with 0.4 mm nozzles – it is recommended to check the filament manufacturer's datasheet to avoid clogging.
