| Property | QIDI Plus4COREXY | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | QIDI | UniFormation |
| Class | COREXY | RESIN |
| 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] | UniFormation GKtwo 10.3" 8K Resin Printer[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 documented |
| 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] | $749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[3] |
| 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] | UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[3] |
| Market position: superseded?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 | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[6][7] | Not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] | 228 x 128 x 245 mm[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 505 x 487 x 550 mm[5] | 350 x 315 x 455 mm[3][4] |
| Net weight (kg) | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] | 20 kg packaged (UniFormation publishes package weight, not net weight)[3][4] |
| Frame construction & material | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[1][5] | Open-frame MSLA with a UV-blocking cover[3][4] |
| 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] | MSLA — photocuring LCD, single Z axis, straight-lift peel[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] | Not documented |
| Max acceleration (claimed, mm/s²) | <=20,000 mm/s2 (manufacturer claim)[5] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened steel dual gears, 1.75 mm filament[1][5] | Not documented |
| 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] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=370 °C claimed. No firmware max_temp verified for this model[1][5] | Not documented |
| Heater cartridge power (W) | 80 W hotend heater (manufacturer figure)[1] | Not documented |
| 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] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[1][5] | Not documented |
| 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] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] | Not documented |

| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch touchscreen, 800 x 480[1][5] | 5-inch touchscreen (control panel — not the masking LCD, see W1)[3][4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz, Ethernet, USB[1][5] | USB file transfer[3][4] |

| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 1-year coverage, 14-day no-reason return, 30-day price protection[1] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[3] |

| Layer exposure times | Not documented | 2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[3][4] |
| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[3][4] |
| Resin vat & feeding | Not documented | Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[3][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.
