| Property | LulzBot TAZ Pro Long BedBEDSLINGER | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | LulzBot | QIDI |
| Class | BEDSLINGER | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LulzBot TAZ Pro Long Bed 3D Printer[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) | $7,995.00 at MatterHackers, listed as currently unavailable, checked Aug 2026[1] | $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) | Not simply a longer TAZ Pro. The Long Bed ships the Asteroid 285 tool head with a 1.2 mm nozzle, a 0.3-0.9 mm equipped layer range, an 80 °C bed cap (vs 110 °C), 150 mm/s travel (vs 300) and BLTouch 32-point mesh levelling (vs 4-point contact). Bed material also differs: blue spring-steel magnetic flex rather than glass with PEI film[1][4] | 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| Market position: superseded?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? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 282 x 582 x 285 mm[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] |
| Net weight (kg) | Not documented | 33 kg net[3] |
| Frame construction & material | Open frame; GT2 belt drive with Igus SST rods and polymer bushings[1] | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed with a heated chamber[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bedslinger[1] | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic TMC2130[1] | Not documented |
| 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] |
| Max travel speed | 150 mm/s maximum travel speed, firmware-limited[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Asteroid 285 tool head[1] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| Filament diameter | 2.85 mm standard, 1.75 mm optional[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 290 °C maximum, firmware-limited[1] | 350 °C on the high-temperature extruder assembly[2][3] |
| Stock nozzle size & sizes included in box | 1.2 mm GammaMaster steel[1] | 0.4 mm nozzle diameter[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | GammaMaster steel[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 °C maximum bed temperature — notably lower than the base TAZ Pro[1] | Not documented |
| Bed heater type (DC/AC mains) & wattage | 360 W, 24 V silicone bed heater[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Blue spring-steel magnetic flex bed system[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | BLTouch, 32-point automatic mesh calibration[1] | Not documented |
| Mesh grid size (probe point count — firmware evidence) | 32 points[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensor with runout and stripping detection[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | 32-bit Archim 2.2b with Trinamic TMC2130 drivers[1] | Not documented |
| PSU (brand, wattage, rail voltage) | 500 W 24 V Mean Well, auto-switching, 100-240 VAC input[1] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | Not documented | 700 W rated[3] |

| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification)[1] | Not documented |
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.
