| Property | QIDI Plus4COREXY | QIDI X-Smart 3COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[1][2] | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[3][4] |
| Release date (announcement and actual shipping) | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| Street price (USD; dated snapshot per entry) | $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[1][2] | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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)[2][1] | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[3][6][7] |
| Market position: superseded? successor announced? | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[8][9] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[1][5] | 175 x 180 x 170 mm advertised[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 505 x 487 x 550 mm[5] | 370 x 362 x 397 mm[3] |
| Net weight (kg) | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] | 10.5 kg[3] |
| Frame construction & material | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[1] | QIDI publishes no frame-material breakdown for this model[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[1][5] | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[1][5] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[5] | CoreXY[3][4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Dual independent Z motors on 10 mm linear shafts and screws[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s (manufacturer claim, tool-head maximum)[5] | <=500 mm/s (manufacturer claim)[3][4] |
| Max acceleration (claimed, mm/s²) | <=20,000 mm/s2 (manufacturer claim)[5] | 20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | Not documented | 30 mm3/s extruder flow (manufacturer claim)[3][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened steel dual gears, 1.75 mm filament[1][5] | Direct-drive extruder, single, 1.75 mm filament[3][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 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[1][5] | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[3][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=370 °C claimed. No firmware max_temp verified for this model[1][5] | <=300 °C claimed[3][4] |
| Heater cartridge power (W) | 80 W hotend heater (manufacturer figure)[1] | Not documented |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 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[1][5] | <=120 °C claimed[3][4] |
| Bed surface (material, texture, coating), single/double-sided | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[1][5] | Double-sided flexible magnetic RF plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[1][5] | 16-point automatic bed levelling per QIDI's US page; probe technology not named[4] |

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.
