Features

Genuine Creality and E3D Engineering

The ObXidian High Flow Nozzle combines Creality printer compatibility with E3D nozzle technology. It provides an upgraded extrusion solution for users requiring increased material throughput, durability and reliable high-speed printing performance.

Advanced ObXidian Wear Resistance

Featuring E3D's specialised E3DLC coating over hardened nozzle components, the assembly offers enhanced resistance to abrasive filament wear. This makes it suitable for compatible carbon-fibre and glass-fibre reinforced materials that can rapidly wear conventional brass nozzles.

High-Flow Multi-Channel Design

An enlarged melting chamber and innovative internal multi-channel structure increase the surface area available for filament melting. This supports faster thermal transfer and greater material throughput during demanding printing operations.

Up to 43mm³/s Material Flow

The 0.4mm ObXidian nozzle achieves a tested volumetric flow rate of up to 43mm³/s with high-flow PLA under suitable conditions. Actual performance varies by filament, temperature, printer configuration and printing settings.

High-Speed Printing Performance

The upgraded melting chamber supports printing speeds of up to 600mm/s on appropriately configured printers. Its increased extrusion capability helps maintain material delivery during high-speed printing while preserving dependable layer formation.

Precision 0.4mm Nozzle Opening

The standard 0.4mm outlet provides a practical balance between printing detail, extrusion capacity and overall print speed. It is suitable for everyday models, prototypes, functional components and detailed 3D printed objects.

Durable Hardened Steel Nozzle Tip

The SKD11 hardened steel tip provides increased resistance to wear caused by abrasive additives. Its durable construction helps preserve the nozzle opening during extended use with compatible engineering and composite filaments.

Titanium Alloy Heat Break

The titanium alloy heat break reduces unwanted heat conduction towards the upper filament path. This helps maintain the thermal separation required for consistent extrusion and reduces the risk of heat-related filament feeding problems.

Efficient Copper Alloy Heat Transfer

Thermally conductive copper alloy components support efficient heat transfer into the filament melting zone. This contributes to consistent material softening and reliable extrusion at elevated flow rates.

Non-Stick Protective Coating

The ObXidian coating helps reduce molten plastic adhesion to the exterior nozzle surface. This can minimise filament buildup around the nozzle and make routine cleaning more convenient when suitable maintenance methods are used.

Versatile Filament Compatibility

The nozzle supports compatible PLA, PETG, ABS, ASA, TPU, PC, PA and selected carbon-fibre or glass-fibre composite filaments. Material compatibility depends on the complete printer, hotend and operating temperature requirements.

Integrated All-Metal Construction

The nozzle and heat break are integrated into a complete metal assembly designed for convenient servicing. Its construction simplifies replacement compared with traditional multi-part threaded nozzle arrangements.

Designed for Creality K2 Series

The nozzle assembly is compatible with Creality K2, K2 Pro and K2 Plus printers equipped with the appropriate original hotend system. It provides a practical upgrade or replacement for users seeking improved extrusion performance and nozzle durability.

Easy Maintenance and Replacement

The integrated assembly supports convenient nozzle replacement when following the relevant printer servicing procedure. Proper installation helps maintain secure positioning, reliable extrusion and consistent operating temperatures.
