| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Tech i-Fast, also written iFast and "I-Fast"[1][2] | UltiMaker Factor 4[3] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[3] |
| Launch MSRP (USD) | Not documented | Starting at approximately $20,000[3] |
| Street price (USD; dated snapshot per entry) | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[2][1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[2][1] | Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[3] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][4] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 330 x 240 x 300 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | Not documented |
| Net weight (kg) | 33 kg net[2] | Not documented |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Enclosed with actively controlled chamber airflow and a HEPA filter[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | Direct-drive dual extrusion; kinematic layout not stated in the source checked[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[2] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Direct-drive dual extrusion[3] |
| Filament diameter | Not documented | 2.85 mm[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | 340 °C maximum with the high-temperature print core (manufacturer claim)[3] |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| Filament Handling & Detection | ||
| Spool holder location & max spool size; drybox compatibility | Not documented | Automatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[3] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter[3] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 110-220 V[2] | Not documented |
| Total rated power draw | 700 W rated[2] | Not documented |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | Not documented |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[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.
