| Property | QIDI i-FastIDEX | QIDI X-Plus 3COREXY |
|---|---|---|
| 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 X-Plus 3, listed in QIDI navigation as X-Plus3[3][4] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| 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] | $699 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026. 3DJake lists the model as sold out[4][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] | Two headline-speed figures circulate for this model: QIDI's own US page says 600 mm/s and 35 mm3/s, 3DJake's spec table says <=500 mm/s and 30 mm3/s. This is exactly the kind of sibling contamination the 3-series suffers (X-Max 3 is 600 mm/s / 35 mm3/s). Siblings: X-Max 3 (325x325x315, 900 W) and X-Smart 3 (175x180x170, no chamber heat, 300 °C)[3][4][5][6] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 280 x 280 x 270 mm advertised[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 511 x 527 x 529 mm[3] |
| Net weight (kg) | 33 kg net[2] | 24.3 kg net[3] |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | All-metal frame per QIDI's US page; no further breakdown published[4] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Fully enclosed with a heated chamber[3][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, independent chamber heating (manufacturer claim)[3][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | CoreXY[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear optical axis of high-strength steel[3] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Double Z axis[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] | Conflicting manufacturer claims: QIDI's US page says 600 mm/s, 3DJake's spec table says <=500 mm/s. The lower, more conservative figure is used as the sortable value[3][4] |
| Max acceleration (claimed, mm/s²) | Not documented | 20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | Not documented | Conflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[3][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | High-flow direct-drive extruder, 1.75 mm filament[3][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating core. Copper-alloy nozzle head for normal materials, hardened-steel nozzle head for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | <=350 °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[3][4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided flexible magnetic RF plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic bed levelling; probe technology not named[4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament detection fitted; type and location not published[3] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[3][4] |
| Input voltage (110/220 V, switch or auto) | 110-220 V[2] | 100-240 VAC, 50/60 Hz[3] |
| Total rated power draw | 700 W rated[2] | 800 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Klipper[4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch touchscreen, 800 x 480[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | Wi-Fi (150M 2.4G), Ethernet, USB flash drive[3] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1-year coverage (QIDI standard store terms)[8] |
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.
