About this product
The QIDI Max4 Combo pairs the large-format enclosed Max4 CoreXY printer with the QIDI Box multi-material system for multi-color printing straight out of the box. Its 390 x 390 x 340 mm build volume is among the largest in its class, while the 65 degrees C actively heated chamber and 370 degrees C bimetal hotend print ABS, ASA, PA, PC, PPS-CF, and other engineering composites with minimal warping. Closed-loop XY motors with FOC control, a linear X-axis rail, and dual independent Z lead screws keep 800mm/s moves stable across the full bed. The bundled QIDI Box dries four spools of filament at 65 degrees C while printing and switches materials automatically for multi-color models and soluble support structures. A load-cell auto-leveling system delivers zero-offset first layers, the onboard camera detects first-layer and filament failures automatically, and the 3-in-1 filtration (G3 pre-filter, H12 HEPA, activated carbon) reduces odors and particles for indoor use. Compatible with OrcaSlicer, PrusaSlicer, and Klipper/Fluidd.
Features
LARGE 390x390x340mm BUILD VOLUME
Print large single-piece models, cosplay parts, molds, and nested production batches on a 390 x 390 x 340 mm plate - about 55 percent more volume than 300mm-class printers, with a dual-sided textured PEI plate heated to 120 degrees C.
CLOSED-LOOP COREXY MOTION AT 800MM/S
Prints at up to 800mm/s with 30,000mm/s2 acceleration. Closed-loop XY stepper motors with FOC control, a linear X-axis guide rail, and dual independent Z lead screws keep the toolhead stable and precise across the full 390mm bed.
370C HOTEND AND 65C HEATED CHAMBER
The bimetal hotend reaches 370 degrees C and the actively heated chamber reaches 65 degrees C, so ABS, ASA, PA, PC, PPS-CF, and carbon fiber composites print with minimal warping. Peak power draw is 1350W - use a dedicated circuit for long production runs.
ZERO-OFFSET AUTO LEVELING WITH AI CAMERA
A load cell sensor built into the hotend delivers true zero-offset first layers with no manual calibration, while the built-in camera detects first-layer and filament failures automatically. Ships fully assembled with a 5-inch color touchscreen.
QIDI BOX INCLUDED, POLAR COOLER SOLD SEPARATELY
The bundled QIDI Box holds four spools, dries filament at 65 degrees C while printing, and switches materials automatically for multi-color models and soluble support structures. Additional units can be chained for up to 16 colors and are sold separately. Note: the Polar Cooler active chamber cooling module is NOT included with this bundle and must be purchased separately.
