| Property | QIDI i-FastIDEX | Stratasys F370INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | QIDI | Stratasys |
| 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] | Stratasys F370, part of the Stratasys F123 Series[3] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | The F123 series spec sheet carried is revision 0721a (July 2021). Stratasys does not print a launch date on it[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] | Top of the series and the only one with ABS-ESD7, PC-ABS and Diran 410MF07, an Insight software licence, and ProtectAM with US DoD STIG compliance on Red Hat Enterprise Linux. Cabinet and weight are identical to the F170 and F270, so footprint tells you nothing about which model you have[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| Market position: superseded?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] | 355 x 254 x 355 mm (14 x 10 x 14 in)[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 1,626 x 864 x 711 mm (64 x 34 x 28 in)[3] |
| Net weight (kg) | 33 kg net[2] | 124 kg (F120) or 227 kg with consumables (F170, F270, F370)[3] |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Fully enclosed office/classroom-grade cabinet, factory assembled[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Enclosed build chamber[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 110-220 V[2] | 100-132 V / 15 A or 200-240 V / 7 A, 50/60 Hz[3] |
| Total rated power draw | 700 W rated[2] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Proprietary Stratasys firmware; print preparation is GrabCAD Print. The F370 additionally carries an Insight software licence and DoD STIG compliance powered by Red Hat Enterprise Linux[3] |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | Wired TCP/IP at 100 Mbps minimum, 100base-T Ethernet, RJ45. Wireless-ready IEEE 802.11 n/g/b with WPA2-PSK or 802.1x EAP, CCMP/TKIP encryption[3] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | PLA, ABS-ESD7, ABS-M30, ASA, Diran 410MF072, FDM TPU 92A, PC-ABS, ABS-CF10, with QSR soluble support. Diran and PLA use breakaway rather than soluble support[3] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | CE (low-voltage and EMC directives), FCC, EAC, cTUVus, KC, RoHS, WEEE, REACH, RCM[3] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | 46 dB maximum during build, 35 dB idle — manufacturer specification, no distance or method stated, and not an independent measurement[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Parts produced within +/-0.200 mm or +/-0.002 mm/mm, whichever is greater. Manufacturer figure derived from statistical data at 95% dimensional yield; Z accuracy carries an extra -0.000/+slice-height tolerance[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.
