| Property | QIDI i-FastIDEX | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | QIDI | UltiMaker |
| Class | IDEX | INDUSTRIAL |
| 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 S7[3] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Not documented |
| 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] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[3] |
| 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] | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[3][4][5] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][6] | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[5][7] |
| 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] | 495 x 585 x 780 mm with the spool holder[3] |
| Net weight (kg) | 33 kg net[2] | Not documented |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Fully assembled professional chassis[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[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 |
| Max volumetric flow claimed (mm³/s) | Not documented | Build speed under 24 mm3/s (manufacturer figure)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Dual extrusion with swappable print cores[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] | Not documented |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | PEI-coated flexible build plate, 20-140 °C[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI-coated flexible build plate[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] | Wi-Fi 2.4 GHz and 5 GHz, LAN, USB[3] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Under 50 dBA operating sound, manufacturer figure. No independent measurement[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[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.
