Conch Hotend Perfect Fit for Bambu Lab H2D / A1 / A1 Mini Upgraded material suitable for the need of high wear resistance Coating hardness of HV3300 Service life 2.5 times more than that of ordinary hardened steel nozzle EndCoat Ultra-Wear-Resistant Coating Technology Phaetus Proprietary Engineered for high-wear industrial components, this precision applied coating enhances surface hardness and abrasion resistance on critical areas (nozzle tips/heatbreak throats), extending service life up to 2.5x *Service life: ≈30kg with carbon fiber materials (PAHT-CF/PA-CF); Negligible wear and extended lifespan with consumer materials (PLA/PETG). Observable print degradation occurs when nozzle orifice expands >0.05mm due to wear. 10KG PA-CF Wear resistance test Easy to deal with printing wear Specialized in Multi-Filaments Additive Manufacturing Carbon Fiber Glass Fiber Steel Wood Boron Carbide Tungsten Phosphor Pigment Ultimate Cooling Design Precision Manufacturing Stable Printing Innovative Cooling Structure Micron-Level Precision Manufacturing Runice Standard Comparison of Printed Materials Composite material industrial parts Consumer-grade small flame person 30-second Quick Nozzle Replacement The removable nozzle design reduces maintenance costs Hot Tightening Guide To ensure proper hotend function and prevent nozzle leakage during printing, always perform hot tightening when installing or replacing nozzles. Nozzles tightened cold may develop gaps due to metal expansion when heated, causing material leakage. 50 mm³/s* Unlock High-Speed Printing Zero modification required Beyond H2D Hotend Compatibility Plug & Play with A1/A1 mini Conch Hotend on A1 Series Delivers up to 40 mm³/s* Product Volumetric Flow Rate (mm³/s) A1 Stock Hotend 33.25 mm³/s Conch Hotend 40.2 mm³/s Test conditions: PLA, 0.4 mm nozzle, 220 °C, Bambu Lab A1 Product Information Product Information Details Nozzle Diameter Φ0.20 / 0.40 / 0.60 / 0.80 Product Color Black Product Net Weight 22 g Printing Temperature 350 °C Applicable Machine Bambu Lab H2D / A1 / A1 mini Accessories List H5 Open-End Wrench ×1, H3 Box-End Wrench ×1
