- Ultra-Large Build Volume: QIDI Max4 has a 390×390×340mm printing area, 55% larger than its predecessor MAX3, enables you to print large industrial parts, complex molds and custom prototypes in one go without splitting; full-surface silicone heated bed ensures even temperature distribution and strong first-layer adhesion to avoid warping.
- High Precision & Stability: QIDI Max4 3d printer equipped with closed-loop motors on X/Y axes, Achieve a maximum printing speed of 800mm/s and an acceleration of 30,000mm/s²; 2mm lead screw and anti-backlash nut on Z-axis reduce vertical gaps, ensuring smooth and precise printing with excellent surface quality.
- Wide Material Compatibility: 40mm³/s high-flow hotend with hardened steel nozzle supports standard materials (PLA/ABS) and industrial-grade abrasive materials (carbon fiber-reinforced nylon); QIDI Max4 equipped with 65℃ active heated chamber and self-developed Polar Cooler system create ideal printing conditions for high-temperature materials like ABS-CF, PC, PPS-CF.
- Smart Monitoring & User-Friendly Design: Built-in AI camera automatically detects printing abnormalities (e.g., spaghetti-like failures) and pauses printing instantly to save materials and time; large touch screen with optimized interface offers smooth operation, qidi max4 suitable for both professionals and enthusiasts.
- Expandable Multi-Color Printing: Seamlessly connect with QIDI BOX to achieve 16-color and multi-material printing and enjoy intelligent filament management (e.g., real-time filament level monitoring, automatic pause when filament runs out); providing you with a worry-free 3D printing experience.
- Note: The max4 series does not come with the Polar Cooler. The Polar Cooler must be purchased separately.
