The QIDI Tech X-Max 3 is a large-format CoreXY 3D printer with a 325 x 325 x 315 mm enclosed build area. Running Klipper firmware, it reaches 250 mm/s with high precision via a 32-bit controller and stable sheet metal frame. It includes a 300W heated chamber (up to 65°C) for warp-free 3D printing with ABS, ASA, and carbon fiber materials, and comes with two hotends: copper-plated for standard filaments and hardened steel for abrasives like PA-CF and PET-CF. A 6 mm aluminum plate with dual-sided PEI and embedded magnets heats to 120°C for reliable adhesion.
Designed for professional use, the X-Max 3 suits small businesses and makers alike. It features a 5-inch touchscreen, QIDI Slicer (based on Prusa Slicer), and ready-made material profiles for ease of use. A BLTouch handles auto bed leveling, and the dual-gear direct drive extruder supports both flexible and rigid filaments. Dual 24V 450W power supplies ensure consistent, reliable performance for prototyping and small-scale production.
The QIDI X-Max 3 offers ±0.1 mm accuracy, 0.05–0.4 mm layers, and print speeds up to 250 mm/s. It delivers clean PLA prints, precise TPU at 40 mm/s, and warp-free ABS, supported by its CoreXY system, Klipper tuning (resonance compensation, pressure advance), 8×8 BLTouch leveling, and 65°C chamber. The X-Max 3’s performance is shown with a 3D Benchy printed in QIDI Rapido PLA at 0.2 mm layers and 250 mm/s. The model displayed clean overhangs, minimal artifacts, and consistent detail, proving the printer’s accuracy and reliability at high speeds.
When printing high-temp materials, the 65°C heated chamber prevents warping, as seen in ABS prints with strong adhesion and stability. Without heating, edges warp noticeably, while chamber-heated prints stay flat and structurally sound.
The QIDI X-Max 3 handles flexible materials well, shown by a TPU95A-HF wallet printed at 40 mm/s. Despite challenges like stringing and deformation, the print achieved accurate dimensions, strong adhesion, and sharp details. This demonstrates Klipper’s pressure advance and the CoreXY system’s ability to maintain precision with soft filaments.
The QIDI X-Max 3’s dual cooling system uses a 5015 fan for part cooling and an auxiliary fan for chamber airflow, supporting high-speed printing. Its high-flow hotend handles 35 mm³/s extrusion, with a ceramic ring heater heating to 300°C in under 2 minutes for quick material changes. Resonance compensation reduces vibration distortions, ensuring smooth, precise layers at high speeds.
An XYZ Calibration Cube printed at 0.2 mm layers and 250 mm/s showed sharp edges, uniform walls, and cleanly rendered letters without warping or shifts. This confirms the X-Max 3’s precise axis calibration and high geometric accuracy across the build volume, making it suitable for applications requiring tight tolerances.
The QIDI X Max 3’s sheet metal frame and dual Z-axis deliver excellent print accuracy and finish. In the 5-hour “Torture Toaster” test, it produced working parts with tolerances down to 0.3 mm. Smooth gear movement and precise sliding fits highlight its dimensional accuracy and mechanical reliability.
Large-format prints, like a full-size Flexi Fox in PETG, showed consistent wall quality over 10 hours. The 9.5:1 direct drive extruder provided precise filament control, delivering clean surfaces and minimal stringing, even with flexible materials.
The QIDI X-Max 3 large-format 3D printer handles PLA, ABS, ASA, PETG, TPU, and high performance materials such as Nylon, PC, and carbon fiber composites with dual 350°C hotends (one hardened steel), a 120°C bed, 65°C chamber, and a 9.5:1 direct drive extruder for reliable printing of standard, flexible, and abrasive materials.
PETG Print Sample: A full-size Flexi Fox was printed at 0.16 mm layers, 250°C nozzle, 80°C bed, and 250 mm/s speed. The 10-hour print showed strong adhesion and structural integrity throughout.
