Qidi Max4 FDM 3D Printer is a large-format industrial-grade machine engineered for high-performance filaments. With a 390×390×340 mm build volume, 370°C hotend, and 65°C active cha mber heating, it prints PPS-CF, PA-CF, PC, and more without warping. The third-gen heating system ensures uniform temperature, while 800mm/s speed and 30,000 mm/s² acceleration deliver fast, precise results. Features include loadcell auto-leveling, AI camera, 5-inch touchscreen, and Klipper firmware. Compatible with QIDI Box for multi-color printing. Max4 brings industrial reliability to your workshop. Active Cooling Air Control SystemIn combination with active chamber heating, ensure that large-sized PLA does not warp at the edges Reduce the Clogging Situation by 90% Efficient air-cooled direct-blow extruders and filament Cold air blows on the extruder Reduce clogging by 90% Third Gen Active Chamber Heating Reaches up to 65ºCThe air circulation design ensures ideal conditions for printing various filaments Chamber Heating & Polar Cooler ON ensure that large-sized PLA does not warp at the edges OFF: Warping ON: Perfect Model Printing Enters the Era of Industrial-Grade Precision No Wobble, No Ripple With The Shortest Z Travel in Its Class, a 2 mm lead Z-axis screw delivers unprecedented precision. With the new anti-backlash nut, every layer stays perfectly aligned Heated Bed Enters the Industrial-Grade Temperature Control Era The 390×390 mm heated bed features a full-surface silicone layer with dense heating wires and insulation cotton, ensuring even heat, strong first-layer adhesion, and stable temperatures—perfect for large, warp-free prints QIDI Max4: Ultra-Uniform Other Brands: Uneven Efficient industrial-grade output, Unlock size Powerful FOC Closed-Loop Stepper Motor The motor performance has been enhanced by 65%, and the printing speed has been increased to 800mm/s. The acceleration is increased to 30,000 mm/s² Build volume 390×390×340 mmLet your imagination break free from volume constraints Heating up to 370ºCWith a ceramic throat and a new heat dissipation module to reduce clogging. Bimetal hardened steel nozzle for increased durability Unlock Perfect Printing with PPS-CF Engineered for high-performance demands New 1.5GT Custom BeltNew 1.5GT custom belt with higher tooth density for smoother, more precise motion. Minimizes vibration frequency artifact (VFA) for better print quality Flagship-Level Smooth Surface Smart resonance control and 1.5GT belts work together to remove ripple lines that others can’t 5-inch Touch Screen The high-definition touch screen and the upgraded, powerful processor, combined with the new generation of UI design, bring an intelligent and understandable user operation experience AI camera, Ensuring Every Print Actively detect common printing problems, such as Spaghetti, to ensure the safety of your printer Multi-color and multi-material printing The QIDI Box features a built-in chamber heating up to 65°C, gently softening advanced filaments for smooth, vibrant multi-color prints every time For Home Health and Safety Highly efficient at capturing 99.5% of dust and particles * { margin: 0;
