QIDI Max 4 High-Temp Multi-Material 3D Printer
Frequently Bought Together
Built on a full-metal CoreXY frame with FOC closed-loop stepper motors, linear guide rails, and a 2 mm-lead dual Z-axis, the Max 4 is engineered for dimensional accuracy and long-print stability. Its third-generation active chamber heating circulates air up to 65°C, while a full-surface silicone heated bed reaches 120°C — the combination required to print large ABS and nylon parts without edge lift. The direct-drive extruder uses hardened-steel dual gears and a bimetal nozzle, supporting a 40 mm³/s flow rate for high-speed printing of abrasive filaments.
The machine ships with a 5-inch touchscreen, hands-free auto-leveling via a loadcell sensor integrated into the hotend, a 1080p AI camera for spaghetti detection, Wi-Fi/Ethernet/USB connectivity, and a 3-in-1 air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon). It is compatible with the QIDI Box multi-material system, which supports up to 4 chained units for 16-color printing.

Pros & Cons
Pros
- Class-leading build volume — 390×390×340 mm (51.7 L) is 2.3× the print area of a Bambu Lab X1C (256³ = 16.8 L) at a similar price.
- True high-temp capability — 370°C nozzle + 65°C chamber + 120°C bed handles PPS-CF, PC, and nylon that most sub-$1,500 printers cannot.
- Active chamber heating — 3rd-gen PTC with air circulation eliminates warping on large ABS/ASA parts; rare at this price.
- Industrial motion system — CoreXY + FOC closed-loop motors + linear rails + 2 mm-lead Z delivers 0.01 mm XY accuracy and stable long prints.
- High-speed printing — 800 mm/s / 30,000 mm/s² with 40 mm³/s flow; comparable to Bambu X1C's 500 mm/s in real throughput.
- Direct drive with hardened steel — prints abrasive carbon-fiber and glass-fiber filaments without rapid nozzle wear.
- Hands-free auto-leveling — loadcell sensor in the hotend gives true zero-offset first-layer calibration; no BLTouch probe needed.
- AI camera + air filter — 1080p spaghetti detection and H12 HEPA filtration make it suitable for home/office use.
- Expandable multi-material — QIDI Box supports up to 16 colors/materials with 4 chained units; includes 65°C filament drying.
- Open slicer compatibility — works with QIDI Studio, OrcaSlicer, and PrusaSlicer; not locked to proprietary software.
Cons
- Large footprint and weight — 558×578×612 mm and 40 kg net; requires a sturdy table and is not easily moved.
- No native multi-color without accessory — single nozzle stock; QIDI Box (sold separately) is required for multi-material printing.
- Silicone sock degradation at 350°C+ — users report the nozzle sock breaking down after long prints above 350°C; spare socks recommended.
- UI polish lags Bambu — QIDI Studio and the touchscreen UI are functional but less refined than Bambu Studio; community Klipper configs exist as alternatives.
- Return policy can be difficult — multiple Reddit reports note QIDI support is helpful for repairs/parts but reluctant to process full returns.
- PA6 nylon moisture sensitivity — even with chamber drying, PA6 can show surface roughness; PA12 or dry-box storage recommended.
- 0.2 mm layer surface grain — some reviewers note visible stepping at 0.2 mm layers; finer layers (0.12–0.16 mm) yield smoother results.
- Not fully open-source — unlike Prusa, firmware is not fully open; modding requires community-built Klipper configs.
- Power draw during heat-up — combined 1,350W peak (chamber + bed + system) may trip weaker household circuits.
- First-layer adhesion on PEI for PLA — the textured PEI sheet can release large PLA parts mid-print at chamber temps above 50°C; lower chamber temp for PLA.
