QIDI Bimetallic Hotend for Q2 Series - Copper & Titanium Heatbreak, 0.4mm Brass Nozzle, Up to 300°C

For Q2 Series owners seeking a serious upgrade, this bimetallic hotend replaces the stock unit with a precision-engineered thermal solution. The heatbreak combines a copper alloy hot side and titanium alloy cold side, dramatically improving heat separation. This means less heat creep, fewer clogs, and the ability to print a wider range of materials at temperatures up to 300°C. The ultra-smooth inner bore reduces friction, ensuring consistent extrusion and cleaner prints. Direct replacement design makes installation straightforward—no firmware changes or printer modifications required.

Highlights

• Bimetallic heatbreak: copper alloy (hot side) + titanium alloy (cold side) for optimal thermal performance
• Supports high-temperature printing up to 300°C, expanding material compatibility
• Ultra-smooth polished inner bore minimizes friction and improves flow consistency
• Direct replacement for QIDI Tech Q2 Series 3D printers—no modifications needed
• Includes 0.4mm brass nozzle (M6 thread) and aluminum alloy heat block
• Compatible with standard 24V/40W heater cartridge and NTC 100K thermistor (not included)

In daily use

This hotend delivers reliable performance across a wide range of filaments, from standard PLA and PETG to more demanding materials like ABS, ASA, and nylon. The bimetallic design prevents heat from creeping up the filament path, reducing jams and improving retraction consistency. The polished inner bore ensures smooth filament travel, which translates to better dimensional accuracy and surface finish. Whether you're printing functional parts or detailed models, this hotend provides the thermal stability needed for consistent results.
