| Class | INDUSTRIAL | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | FlashForge Guider 3[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Base of a three-model series: Guider 3 (300x250x340), Guider 3 Plus (350x350x600, 250 mm/s, <50 dB, twin sealed 1 kg filament chambers) and Guider 3 Ultra (330x330x600 single-head / 300x330x600 dual-head, two extruders, 350 °C, 7-inch screen, 70 kg). Volumes and extruder counts differ across all three, so series-level spec boxes are unreliable[1][4][5] | 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[3][2] |
| Market position: superseded? successor announced? | 3DJake shows it sold out and no longer stocked; the current FlashForge store carries the Guider 3 Ultra[1][5] | Discontinued; QIDI's current line is the Q, Plus and Max series[3][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 250 x 340 mm advertised[1] | 330 x 250 x 320 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 710 x 510 x 670 mm[3] |

| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Not documented | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder, single[1] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| Hotend & Nozzle | ||

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.
