High Flow Fast Print Extruder Kit（2 Pack）for 3D Printer Bambu Lab H2D ACE Pro 0.4mm Hardened Steel Hotend, Faster Print Speed

Produktbeschreibung

Compatible with Bambu Lab H2D/A1/A1 Mini full series models, plug and play. Core performance breakthrough The patented melt zone geometry optimization design achieves a maximum volume flow rate of 65mm³/s (62.5% higher than the standard nozzle), and with a print head speed of 1000mm³/s, it can shorten the time for complex model printing by 30%. Especially suitable for Bambu PLA-CF/PETG-CF carbon fiber composite consumables, the 0.4mm hardened steel nozzle optimizes the flow channel, while maintaining a 0.15mm layer accuracy, reducing the risk of blockage, and achieving a balance between speed and quality. Precision structural design The integrated hot end component integrates a high-temperature silicone sleeve (2 pieces/set), supports 350℃ high-temperature printing, and is compatible with all types of consumables such as PLA/PETG/TPU/ABS. The inner wall of the flow channel is mirror-polished, and with SKD11 hardened steel material (hardness HRC58-60), it significantly reduces the friction loss of carbon fiber consumables and extends the nozzle life to more than 3 times that of traditional copper nozzles. Modular quick-change system The patented latch structure enables tool-free separation of the hot end and electronic components, and the heating block does not need to be touched during the replacement process (it is recommended to cool to below 50°C). The hot end assembly can be disassembled and assembled in 3 seconds with one hand. The two sets of hot ends can realize fast switching of consumables, greatly shortening the preparation time for multi-color/multi-material printing. Industrial-grade durable configuration The all-metal heating module has passed the 3000-hour continuous working test, and the temperature fluctuation is controlled within ±1°C. The nozzle outlet is precisely laser-processed, and the 0.4mm aperture tolerance is controlled within ±0.01mm. With the double-layer thermal insulation structure, it effectively suppresses the conduction of high temperature to the print head mechanism, ensuring the stability of long-term high-speed printing.
