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.
