Product description Upgrade to High Flow – Faster Prints, Same Precision

Experience a 30% boost in printing speed without compromising detail. Biaysan’s H2D-compatible 0.4mm High Flow Nozzle delivers maximum volumetric flow and stable performance for high-speed 3D printing. Perfect for productivity-driven users.

Boost Speed by 30%

Achieve up to 65mm³/s flow rate and faster toolhead movement—print faster, save time.

Sharp Details, No Compromise

High Flow nozzle eliminates common print defects like under-extrusion and surface artifacts. Get smoother textures, cleaner layers, and better detailing even at high speeds.

Wide Filament Compatibility

Supports high-temp printing up to 350°C. Works seamlessly with PLA, PETG, TPU, ABS and more. Tested with Bambu PLA-CF and PETG-CF to ensure smooth, clog-free extrusion.

Advanced Engineering, Maximum Durability

Crafted with a titanium alloy throat tube and high-precision internal finish (Ra 0.4), this nozzle offers superior thermal efficiency, reduced clogging, and exceptional lifespan. Built to endure the demands of high-speed, high-volume 3D printing.

Advanced Structure, Fewer Clogs

The HF.4 nozzle features a titanium alloy throat tube with ultra-smooth Ra 0.4 inner surface and a wall thickness of only 0.25 mm. This optimized structure minimizes flow resistance, reduces clogging risk, and improves extrusion consistency—especially under high-speed printing conditions.

Quick-Release in 30 Seconds – No Tools Needed

The H2D hotend features a tool-free quick-detach design for fast and safe replacement. With no electronic connectors between the toolhead and heater block, maintenance becomes effortless.

Perfect for fast swaps and minimal downtime – simply unlock and pull down.
