H2O extruder water cooling extruder 500℃ high temperature hotend direct drive extruder dual gear for  3D printer kits

• The BIQU H2O extruder is a next-level water cooling extruder built for extreme-temperature 3D printing and stable long-run performance.
• Unlike standard air-cooled setups, this direct drive extruder is designed to work with a separate water cooling kit (sold separately) to keep the extruder body temperature under 50°C while the hotend supports up to 500°C printing.
• That combination helps deliver more consistent extrusion, better thermal control, and longer service life—especially in demanding, high-heat environments.
• Built as an upgrade over the H2 V2.0 platform, the H2O water cooling extruder uses a powerful 70W heater cartridge paired with a nickel-plated red copper heat block and a hardened-steel nozzle to enable 500°C high temperature hotend performance.
• This makes it suitable for a wide range of materials, from everyday filaments like PLA, ABS, PETG, and TPU to more demanding options such as PP, PC, and Nylon (printing results depend on your printer setup, enclosure, and slicer tuning).
• For motion control and feed reliability, the dual gear system uses stainless-steel output and transmission gears for consistent grip and smooth material delivery.
• The narrowed 0.25 diameter output gear is designed to improve smooth extrusion, helping reduce slipping and improve surface finish—useful for both high-flow moves and precision prints.
• Temperature monitoring is handled by a PT100 thermistor with a MAX31865 converter, providing more linear and accurate readings across a wider temperature range—critical for stable printing at higher temperatures.
• A built-in RGB light adds practical visual feedback for toolhead status and aesthetics on modern builds.
