| Property | FlashForge AD5XCOREXY | QIDI Plus4COREXY |
|---|---|---|
| Identity | ||
| Brand | FlashForge | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Flashforge AD5X, sold as "AD5X - Multicolor 3D Printer for High-Speed, Full-Color Printing"[1][2] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[3][4] |
| Release date (announcement and actual shipping) | Not documented | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] |
| Street price (USD; dated snapshot per entry) | $399.00 sale against a $549.00 compare-at price on flashforge.com, in stock, with a further $50 off at checkout, checked Aug 2026. A refurbished AD5X is listed at $315.00[1][2] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[3][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Shares the 220 mm Adventurer chassis with the 5M and 5M Pro but differs on the points that matter: 300 °C nozzle (vs 280 °C), 4-colour IFS unit, NO air filtration, NO auto shutdown, and a 300 mm/s print speed against a 600 mm/s travel speed. 3DJake and eolasprints both describe it as open-frame[1][6][7][8] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[4][3] |
| Market position: superseded? successor announced? | Not documented | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[9][10] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 220 mm advertised[1][6] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[3][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 505 x 487 x 550 mm[5] |
| Net weight (kg) | Not documented | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] |
| Frame construction & material | Not documented | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[3] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure and no air filtration — FlashForge's own table records "Air Filtration: No". Chamber lighting and remote monitoring are listed as expandable options rather than fitted[1][7] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[3][5] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[3][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[7] | CoreXY[5] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual independent Z motors on 10 mm linear shafts and screws[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | FlashForge publishes two separate figures: max travel speed 600 mm/s and max print speed 300 mm/s. The 300 mm/s print figure is the one that describes printing[1][6] | 600 mm/s (manufacturer claim, tool-head maximum)[5] |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 maximum (manufacturer claim)[1][6] | <=20,000 mm/s2 (manufacturer claim)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive, one extruder, fed by the 4-colour Intelligent Filament System (IFS)[1] | Direct drive with hardened steel dual gears, 1.75 mm filament[3][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[3][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 °C claimed[1][6] | <=370 °C claimed. No firmware max_temp verified for this model[3][5] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[3] |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.25, 0.6 and 0.8 mm optional[1][6] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 °C claimed[1][6] | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[3][5] |
| Bed surface (material, texture, coating), single/double-sided | PEI flexible spring-steel sheet[1][6] | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[3][5] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling; probe technology not named[1][6] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[3][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; type and location not published[1][6] | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] |
| Multi-material/multi-color capability or official upgrade path | Four-colour printing via the integrated Intelligent Filament System (IFS), which handles filament switching[1] | QIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[3][4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5] |

| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[5] |
| Total rated power draw | Not documented | 450 W plus 400 W for chamber heating (rated)[5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by FlashForge; the supported slicers are Orca-Flashforge and OrcaSlicer[1] | Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch touchscreen, 800 x 480[3][5] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Ethernet, Wi-Fi[1][6] | Wi-Fi 2.4 GHz, Ethernet, USB[3][5] |
| Cloud service & phone app; LAN-only mode possible? | Not documented | Mobile and computer control, remote cloud or LAN-only operation[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in low-frame-rate camera, up to 1080p, timelapse supported[3][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | QIDI claims about 10 minutes from unbox to printing[3] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Power-outage recovery supported; mechanism not published[1][6] | Power-loss recovery listed; mechanism not published[5] |
| Materials Support | ||
| Officially supported filament list | PETG, PLA, TPU95A, TPU64D-75D, PLA-CF, PETG-CF[1][6] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[3][5] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1-year coverage, 14-day no-reason return, 30-day price protection[3] |
Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
