Bamboo Lab 2-Pack Enhanced-Flow Hardened Steel Nozzle Set for Bambu Lab H2S / H2

• Upgraded Rapid-Melt Heat Block — Faster Heating & 500°C Stability: The hotend features a chromium-zirconium copper heat block with nickel plating, delivering exceptional thermal conductivity and stable performance up to 500°C. It heats faster, transfers heat more evenly, and maintains consistent extrusion during long or high-speed prints.
• Enhanced-Flow Nozzle Design for High-Speed Extrusion: The optimized melt zone improves filament liquefaction efficiency, enabling significantly higher extrusion throughput. This results in up to 62.5% higher volumetric capability and noticeably shorter print times—perfect for large models and prints with heavy infill.
• Ultra-Smooth Surfaces & Zero Under-Extrusion: Say goodbye to rough layers, gaps, and weak bonding. The upgraded internal geometry ensures stable, continuous extrusion with crisp edges, detailed texturing, and ultra-smooth surfaces—even when printing at high speeds.
• Premium Hardened Steel — Built for Abrasive Filaments: Made of hardened steel, the nozzle withstands long-term use with carbon fiber, glass fiber, metal-filled, and other abrasive filaments. Durable, wear-resistant, and ideal for professional high-speed and engineering-grade printing.
• Perfect Compatibility & Bonus Silicone Cover: Fully compatible with Bambu Lab H2S / H2D / H2D Laser / A1 Series hotend systems. (Note: On A1 printers, extrusion speed remains similar to standard nozzles.) Package includes one upgraded hotend + one spare silicone sock to keep your nozzle clean and improve temperature stability.

Upgrade your Bambu Lab printing performance with this enhanced-flow hotend and hardened steel nozzle set. Designed specifically for H2S, H2D, and H2D Laser systems, this hotend features a high-conductivity chromium-zirconium copper heat block with nickel plating, ensuring rapid heat transfer, reliable temperature control, and stable operation up to 500°C. The redesigned melt zone enables faster filament softening and smoother extrusion, allowing significantly higher volumetric output during high-speed printing. Whether you’re producing large mechanical parts or dense infill models, you’ll enjoy noticeably reduced print time without sacrificing accuracy. The precision-machined hardened steel nozzle delivers long-lasting durability, especially when printing abrasive materials such as carbon fiber, glass fiber, or metal-filled filaments. Its optimized internal flow path ensures consistent extrusion, eliminating under-extrusion and improving overall surface finish for crisp, detailed prints. This kit is fully compatible with Bambu Lab H2S, H2D, H2D Laser, and can also be used on A1 Series printers. An extra silicone sock is included to maintain a clean nozzle and improve temperature stability throughout your prints. Upgrade your printer’s speed, consistency, and reliability—perfect for makers, professionals, and high-speed printing enthusiasts.
