| Property | QIDI i-FastIDEX | QIDI Plus5COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | QIDI |
| Class | IDEX | COREXY |
| 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] | QIDI Plus5, sold as "QIDI Plus5 3D Printer"[3][4] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Launched 5 August 2026, 09:00 EDT / 15:00 CEST[5] |
| Launch MSRP (USD) | Not documented | $749 regular launch price; a launch-window member discount put it under $700[5] |
| 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] | $749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[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] | Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[3][5] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][6] | Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[3][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[3][4][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 500 x 488 x 558 mm[4] |
| Net weight (kg) | 33 kg net[2] | 29.0 kg net[4] |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Fully enclosed, with a 3-stage air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[3][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated, 550 W chamber heater — reported as a 37.5% increase in heater power over the Plus4 (manufacturer claim)[4][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | CoreXY[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | High-precision linear rails on X[3][5] |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5GT belts, 9 mm wide — wider than the 2GT 6 mm belts common in this class[3][5] |
| 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] | 600 mm/s (manufacturer claim)[4] |
| Max acceleration (claimed, mm/s²) | Not documented | <=20,000 mm/s2 (manufacturer claim)[4] |
| Vibration Compensation / Input Shaping | ||

| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Direct drive with hardened dual gears[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating-plate hotend with a bimetal nozzle; 0.4 mm standard, 0.2/0.6/0.8 mm optional[4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | <=370 °C claimed[3][4] |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=120 °C claimed, described by QIDI as an even-heating bed[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.
