QIDI PLUS4 3D Printer 

9MM Belts - 65c actively heated Chamber - 370c Hot end - Core XY

The Qidi Tech Plus4 is a feature-rich FDM 3D printer, designed for handling large, high-performance, and fiber-reinforced prints with its large build volume of 305 x 305 x 280 mm. This makes it suitable for large and complex projects. The printer boasts several upgrades over its predecessor, particularly around flexibility, precision, and usability.

Key Features and Upgrades:

Versatile Toolhead:

• Multi-metal composite nozzle: Hardened tip for wear resistance, capable of printing high-temperature filaments, including fiber-reinforced types.
• Enhanced cooling system: Larger hotend fan and advanced air duct system for better temperature control.
• Improved throat nozzle design: Ensures better heat transfer, minimizes clogs and leakage, and allows faster jam removal and maintenance.

Drive System:

• Equipped with dual motors, 10 mm linear shafts, and bearings, which ensure precise movement and print quality.
• A 6 mm aluminum print bed provides excellent flatness for consistent printing.

Active Chamber Heating:

• 400-watt heater can warm the chamber to 65 °C in 8 minutes, ensuring improved temperature consistency and print quality for advanced materials. The double-layer insulated chamber adds energy efficiency.

Additional Features:

• Quick setup in just 10 minutes with a new, user-friendly interface and a 5-inch HD touchscreen.
• Comprehensive filament detection system: Features filament runout detection and filament tangle detection, ensuring smoother prints.
• High-speed printing: Capable of up to 600 mm/s with acceleration up to 20,000 mm/s², reducing print times.
• Klipper firmware (V0.12.0): Advanced control with reduced ghosting and ringing, enabling smoother prints at higher speeds.
• Remote printing through the QIDI Mobile App.

Supported Filaments:

Handles a wide range of filaments, including PLA, ABS, ASA, PETG, TPU, PA, PC, CF (carbon fiber), and GF (glass fiber).
