BIQU H2 500°C extruder upgrade all metal hotend  printing 1.75mm filament  with PT100 Max31865 for  printer kits

• BIQU H2 500°C extruder is a compact, pre‑assembled direct-drive extruder upgrade built for high‑temperature 3D printing and demanding materials.
• The all‑metal hotend (no PTFE in the heat zone) supports stable extrusion at elevated temperatures, while PT100 + MAX31865 improves accuracy for high-temp sensing.

Features

• 500°C max temperature: Built for high‑temp/engineering filaments (printer/firmware must support 500°C operation).
• All‑metal hotend: Titanium heat break, no PTFE path in the hot zone.
• Hardened steel nozzle (0.4mm): Better for abrasive and high-temp materials.
• PT100 + MAX31865: More accurate high‑temperature sensing versus standard thermistors.
• Compact BIQU H2 integrated design: Pre‑assembled for easier installation in many printer kits.
• High-speed cooling: 9000 RPM fan for improved heat dissipation.
• Dual-gear extrusion: Strong, consistent feeding with geared drive.
