| Class | COREXY | INDUSTRIAL |
| 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] | UltiMaker S8 3D 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] | Launched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[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] | Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[3][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] | Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[3][4] |
| Market position: superseded?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 | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[6][7] | Not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 |

| Machine footprint (mm) & clearance needed (cable/spool overhang) | 505 x 487 x 550 mm[5] | 495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[3][4] |
| Net weight (kg) | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] | 30 kg printer only; 47.7 kg as the Pro Bundle[3][4] |
| Frame construction & material | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[1] | Fully assembled, made in Europe[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] | Build-volume temperature under 50 °C with open-loop control (manufacturer figure)[3][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[5] | Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[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] | Swappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[3][4] |

| 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.

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.
