The US Federal Communications Commission granted radio approval on 10 September 2026 to a QIDI Technology device identified as Smart 5. Its filings describe a compact enclosed CoreXY desktop printer with a 180 × 180 × 180 mm build volume, positioned primarily for PLA and PETG. FCC authorization evaluates radio compliance; it is not a product review, quality certification or commercial launch announcement.

The records therefore establish two narrow facts: a Smart 5 hardware configuration was submitted for certification and its 2.4 GHz radio system completed the FCC process. They do not establish that the machine will ship unchanged, at a particular price or on a particular date. No official QIDI product page or launch release was available when this article was completed.

Compact CoreXY with a conditional build volume

The listed enclosure measures 322 × 344 × 410 mm and weighs 10 kg. The X and Y axes run on 8 mm steel shafts, while one motor and a toothed belt drive Z. A 180 mm cube targets desktop entry-to-midrange jobs, but the data sheet says the full area is available only after removing the filament-cutter mount. Nominal and usable space may therefore differ when the multicolour workflow is installed.

CoreXY geometry does not guarantee fast production. The filing lists up to 600 mm/s and 20,000 mm/s², without a reference material, layer height, volumetric-flow condition or quality threshold. On a 180 mm machine many moves cannot reach peak velocity. Average acceleration, melt flow, cooling, resonance and slicer limits determine the real time saving.

Hot end, bed and material boundary

A ceramic-plate heater brings the quick-replace hot end to a maximum of 300°C. The extruder uses a hardened-steel drive gear, 1.75 mm filament and a 0.4 mm nozzle. The aluminium bed reaches 80°C and carries a double-sided plate. High nozzle temperature does not by itself make this an engineering-polymer machine: the submitted sheet explicitly does not recommend ABS or ASA and limits the intended range to PLA and PETG.

That combination suggests the 300°C figure is headroom rather than evidence of a heated-chamber platform. Active chamber temperature, sustained melt flow and nozzle material are not fully documented. Abrasive filled filament would require evidence for nozzle wear resistance as well as the hardened drive gear.

Sensors, camera and QIDI Box

A load cell in the hot end supports automatic levelling. Resonance compensation, a filament sensor and power-loss recovery are listed. The camera offers up to 1080p, time-lapse recording and AI error detection. Resolution is not a measure of detection reliability; no public test defines supported fault classes, false alarms or where images are processed.

The documents say clog and tangled-filament detection require the separately available QIDI Box. The same accessory enables multicolour printing. This is a material cost and capability boundary: features of the base machine should not be conflated with those of the Box-equipped system.

Interface and software

The machine uses a 4-inch touchscreen and 32 GB of eMMC storage, with 2.4 GHz Wi-Fi and USB. QIDI Studio, OrcaSlicer and PrusaSlicer are named, alongside STL, OBJ, 3MF and STEP input. STEP support most likely refers to slicer import rather than parametric CAD editing on the printer itself.

The data sheet lists 150 W power consumption. That is not annual energy use and may not describe every instantaneous operating state. Comparable energy figures require the same material, bed temperature and complete print task.

What remains unknown

The FCC material provides no price, sales region, warranty, noise result, sustained flow, dimensional-accuracy result or release date. Schematics and a block diagram remain confidential for an extended period. The 600 mm/s figure, camera functions and multicolour accessory are therefore specifications, not independently measured buying advantages.

Verified fact and editorial conclusion

The FCC identifier, certification date and configuration quoted from the filing are verified. 3Druck's editorial report traces the specifications to that record. LAYERTIMES concludes that Smart 5 could become the base of a compact and possibly lower-cost CoreXY ecosystem, but a buying decision should wait for QIDI's launch, final price, Box bundles and independent melt-flow and print-quality tests.
