Frequently Bought Together
Overview
The QIDI Plus 4 is a fully enclosed, large-format CoreXY 3D printer designed for users who need both a generous build area and the ability to print engineering-grade materials reliably. Its second-generation 400W active PTC chamber heater reaches 65°C with air circulation, eliminating warping on ABS, ASA, and nylon parts up to 305 mm. The 80W bimetal hotend with ceramic heat break reaches 370°C, supporting PPS-CF and high-temperature nylon. The 6mm aluminum bed with dual-sided textured PEI provides a flat, reliable printing surface. Klipper V0.12.0 firmware delivers 600 mm/s print speeds with input shaping and pressure advance. A 5-inch 800×480 touchscreen, 1080p camera, Wi-Fi/Ethernet/USB connectivity, and 32GB eMMC storage round out the feature set.

Pros & Cons
Pros
- Active 65°C chamber — the only sub-$800 printer with active chamber heating at 305mm size; eliminates ABS/nylon warping
- 370°C hotend — 20°C higher than Creality K2 Plus (350°C), 70°C higher than Bambu X1C (300°C); supports PPS-CF
- Large 305×305mm bed — 39% more volume than Bambu P1S/X1C; nests 25+ small parts per run
- CoreXY + 10mm linear rods — rigid, precise motion with reduced VFA artifacts via 9mm 1.5GT belts
- Klipper open-source firmware — input shaping, pressure advance, Fluidd web UI, active community
- 6mm aluminum bed — flatter and more durable than flexible spring steel beds; dual-sided PEI
- Dual-sensor auto-leveling — reliable first-layer calibration with no manual adjustment
- Filament runout + tangle detection — prevents wasted prints from spool issues
- All3DP 2025 award — recognized as Best Mid-Size 3D Printer
- 10-minute setup — fully assembled, auto-calibrates out of the box
Cons
- QIDI Studio less polished — file browser has no sorting; repeated "vent for PLA" prompt won't stay dismissed; behind Bambu Studio in UX
- Firmware update regressions — V1.6.0 broke OctoEverywhere/Moonraker connections for some users; QIDI Link connectivity issues reported
- No native multi-color — QIDI Box sold separately (~$300–400) and less mature than Bambu AMS / Creality CFS
- Activated carbon only — no HEPA filtration (unlike QIDI Q2's H12 HEPA); ABS fumes partially filtered
- 5-inch screen 800×480 — lower resolution than Bambu X1C's 1280×720 display
- 26 kg weight — heavy for one person to move; requires sturdy table
- Spool holder location — some users find the side-mounted spool holder awkward; easily modded
- Hotend fan mod recommended — community mods improve hotend cooling for high-temp printing
- Discontinued in some markets — replaced by QIDI Plus5 in EU/JP; parts availability may decline long-term
- No LIDAR — lacks Bambu X1C's LIDAR-based first-layer inspection and flow calibration
Performance Highlights
ABS Printing at Full Bed Size
The Plus 4's 65°C active chamber with air circulation enables warp-free ABS printing on the full 305×305 mm bed. A 280×280×80 mm ABS enclosure printed at 60°C chamber showed zero corner lift and consistent layer bonding — a result that passive-enclosure printers (Bambu P1S, X1C) cannot match at this size. The 400W PTC heater reaches 60°C in approximately 5 minutes.
High-Temperature Materials
The 370°C hotend with ceramic heat break and 80W heating power supports PPS-CF (printing at 340–360°C), PAHT-CF (300–330°C), and polycarbonate (280–310°C). The integrated throat and nozzle design reduces clogging and leaks at high temperatures. The multi-metal composite nozzle with hardened tip handles carbon-fiber and glass-fiber filaments without excessive wear.
Speed & Quality
Klipper input shaping and the VFA Avoiding Algorithm enable 600 mm/s printing with reduced ringing and ghosting. A standard 3DBenchy at 0.2mm layers completes in approximately 20 minutes at quality settings (250 mm/s walls). The 9mm 1.5GT belts with higher tooth density reduce vibration frequency artifacts compared to standard GT2 belts.
