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 Plus5, sold as "QIDI Plus5 3D Printer"[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]Launched 5 August 2026, 09:00 EDT / 15:00 CEST[6]
Launch MSRP (USD)Not documented$749 regular launch price; a launch-window member discount put it under $700[6]
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[7][8]$749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[2]
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][9][10][11]Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[2][6]
Market position: superseded?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[7]Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[2][12]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 180 mm (manufacturer figure)[1]320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[2][3][6]
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]500 x 488 x 558 mm[3]
Net weight (kg)5.5 kg net[1]29.0 kg net[3]
Frame construction & materialSteel plus extruded aluminium chassis[1]Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed, with a 3-stage air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[2][3]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated, 550 W chamber heater — reported as a 37.5% increase in heater power over the Plus4 (manufacturer claim)[3][6]
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[10]CoreXY[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[10]High-precision linear rails on X[2][6]
Y-axis guide typeHorizontal linear guide rail carrying the print platform, belt-driven in Y[10]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[10][11]Not documented
Belts (type, width, e.g. Gates?)Not documented1.5GT belts, 9 mm wide — wider than the 2GT 6 mm belts common in this class[2][6]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]600 mm/s (manufacturer claim)[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]Not documented
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedResonance compensation listed as a feature; implementation not named on the product page[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][10]Direct drive with hardened dual gears[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][10]Ceramic heating-plate hotend with a bimetal nozzle; 0.4 mm standard, 0.2/0.6/0.8 mm optional[3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]<=370 °C claimed[2][3]
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][10]<=120 °C claimed, described by QIDI as an even-heating bed[2][3]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1]Aluminium silicone heated bed with a dual-sided textured PEI plate[3]
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][10]Automatic levelling using an integrated load cell; QIDI describes it as direct nozzle-contact detection[3][6]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry and filament-tangle sensor[1]Filament run-out sensor, plus a filament cutter[3]
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[8]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[8][14]Not documented
Reliability, Support & Ecosystem

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.
