Identity
BrandBambu LabQIDI
ClassBEDSLINGERCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab A1 mini. Store title: "Bambu Lab A1 mini 3D Printer"[1]QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[2][3]
Release date (announcement and actual shipping)Shipped in the second half of 2023; Tom's Hardware published its A1 mini review on 13 October 2023, ahead of the full-size A1 review of 14 December 2023[4][5]Not published by QIDI on the pages checked (Aug 2026)[2][3]
Street price (USD; dated snapshot per entry)From $219.00 (base A1 mini) on the Bambu Lab US store, Aug 2026, during an advertised Back-to-School sale; the product page lists A1 mini and A1 mini Combo variants[6][7]$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two SKUs: A1 mini and A1 mini Combo (adds the AMS lite). Distinguish from the full-size A1 by build volume (180 vs 256 mm cube), bed ceiling (80 vs 100 C), screen (2.4 vs 3.5 inch), Z drive (single leadscrew with a coupling vs dual leadscrews belt-synced) and weight (5.5 vs 8.3 kg)[1][8][9][10]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][11][12]
Market position: superseded? successor announced?Still the entry model in the Bambu Lab US store line-up in Aug 2026 and the cheapest machine listed[6]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 180 mm (manufacturer figure)[1]175 x 180 x 170 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)347 x 315 x 365 mm (Bambu tech specs; Tom's Hardware prints 347 x 314 x 365 mm)[1][4]370 x 362 x 397 mm[2]
Net weight (kg)5.5 kg net[1]10.5 kg[2]
Frame construction & materialSteel plus extruded aluminium chassis[1]QIDI publishes no frame-material breakdown for this model[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger: toolhead on an X guide rail and crossbeam, print platform moving in Y on a guide rail, toolhead carried in Z[9]CoreXY[2][3]
X-axis guide type (rods / linear rails / V-wheels; size)Horizontal linear guide rail with the printhead on a sliding block; rail size not published[9]Not documented
Y-axis guide typeHorizontal linear guide rail carrying the print platform, belt-driven in Y[9]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashSingle leadscrew with nut, coupling and stepper motor - the motor drives the leadscrew directly through the coupling. This is the clearest hardware difference from the A1, which uses two leadscrews synchronised by a belt[9][10]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]<=500 mm/s (manufacturer claim)[2][3]
Max acceleration (claimed, mm/s²)10000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20,000 mm/s2 (manufacturer claim)[3]
Max volumetric flow claimed (mm³/s)28 mm3/s claimed on a 150x150 mm single-wall model in Bambu ABS at 280 C - note this is the ABS figure quoted for a machine whose own spec sheet lists ABS as not recommended[1]30 mm3/s extruder flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears; toolhead also holds the cutter unit, filament hub and filament sensor[1][9]Direct-drive extruder, single, 1.75 mm filament[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal integrated hotend (nozzle plus heatsink in one unit), quick-swap; stainless-steel nozzle, 0.4 mm included, 0.2/0.6/0.8 mm optional[1][9]Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]<=300 °C claimed[2][3]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit80 C max build-plate temperature - the lowest of the current Bambu range, and the reason ABS/ASA are listed as not recommended[1][9]<=120 °C claimed[2][3]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1]Double-sided flexible magnetic RF plate[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Nozzle-touch automatic bed levelling and automatic Z-offset; Tom's Hardware confirms the nozzle itself is the probe[4][9]16-point automatic bed levelling per QIDI's US page; probe technology not named[3]
Mesh grid size (probe point count — firmware evidence)Not documented16 points (QIDI's US page). Not verified against firmware[3]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry and filament-tangle sensor[1]Filament detection fitted; type and location not published[2]
Multi-material/multi-color capability or official upgrade pathOptional AMS lite (A1 mini Combo); AMS / AMS 2 Pro / AMS HT need an AMS HUB (SA013) accessory[7]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne custom 5015 centrifugal part-cooling fan with two opposing outlets; closed-loop control. A separate MC board cooling fan is also fitted[1][9]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Bambu names the motion controller as a dual-core Cortex-M4; no board model or chip markings published[1]Not documented
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedCortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2]
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 50/60 Hz[2]
Total rated power draw100-240 VAC 50/60 Hz; max power 150 W for the whole machine. Bed heater wattage is not published separately[1]350 W rated[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[13]Klipper[3]
Connectivity, UI & Camera
Display: size, type, touch?2.4-inch 320x240 IPS touchscreen[1]4.3-inch touchscreen[3]

Calibration Routines & QoL
Assembly level & time from unbox to first printArrives mostly pre-assembled - only the filament wiper, spool holder and Bowden tubes to fit[4]Not documented
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET and fibre-reinforced polymers[1]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Manufacturer claim only: the US store page claims "49dB Whisper-Quiet Operation" - the identical sentence appears on the A1 page, so treat it as line-level marketing copy rather than a per-model measurement. No independent dB measurement with a stated distance was found[7][14]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[15]1-year coverage (QIDI standard store terms)[16]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (13 October 2023)[4]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.
