| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X2D; spec PDF header "X2D Spec"[1] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3] |
| 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)[4] |
| Street price (USD; dated snapshot per entry) | From $649.00 on the Bambu Lab US store, Aug 2026; the compare page shows the same $649 figure[5] | $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[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Dual-nozzle machine: a main hotend with a permanent-magnet synchronous extruder motor and an auxiliary hotend with a plain stepper motor, so the two nozzles are not equivalent. Bambu publishes four different build volumes depending on which nozzle is used, and a shorter list of materials for the auxiliary nozzle. Physical dimensions (392x406x478 mm) are shared with the P2S but the X2D is 16.25 kg against the P2S's 14.9 kg[1][6] | 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)[3][2] |
| Market position: superseded? successor announced? | Current model, launched into the slot vacated by the discontinued X1-Carbon[5] | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[7][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Main nozzle 256 x 256 x 260 mm; auxiliary nozzle 235.5 x 256 x 256 mm; dual-nozzle printing 235.5 x 256 x 256 mm; total volume for two nozzles 256 x 256 x 260 mm. The sortable figure below is the main-nozzle volume[1] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 392 x 406 x 478 mm[1] | 505 x 487 x 550 mm[4] |
| Net weight (kg) | 16.25 kg net[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[4] |
| Frame construction & material | Plastic and steel chassis; plastic, glass and metal outer frame[1] | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a door sensor, active chamber heating to 65 C, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack with an external exhaust fan[1] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 65 C (manufacturer figure)[1] | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - not stated in the spec sheet; Bambu groups the X2D with its enclosed CoreXY machines and publishes the same 20000 mm/s2 acceleration figure[1] | CoreXY[4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual independent Z motors on 10 mm linear shafts and screws[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 600 mm/s (manufacturer claim, tool-head maximum)[4] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | <=20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Two direct-drive extruders: main extruder with hardened-steel gears driven by a Bambu high-precision permanent-magnet synchronous motor, auxiliary extruder with hardened-steel gears driven by a stepper motor[1] | Direct drive with hardened steel dual gears, 1.75 mm filament[2][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Dual hardened-steel nozzles; 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; built-in filament cutter[1] | 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[2][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=370 °C claimed. No firmware max_temp verified for this model[2][4] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 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[2][4] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate, Textured PEI included; Smooth PEI, Cool Plate SuperTack and Engineering Plate supported[1] | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][4] |
| Leveling & Z-Offset | ||
