BrandBambu LabQIDI
ClassBEDSLINGERCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab A2L[1]QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3]
Release date (announcement and actual shipping)Pre-orders opened 1 June 2026 (Tom's Hardware spec box); Tom's Hardware review published 27 June 2026[4]Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][5]
Launch MSRP (USD)$469 standalone, $569 Combo at launch[4]Not documented
Street price (USD; dated snapshot per entry)From $469.00 on the Bambu Lab US store, Aug 2026[6]$1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Standalone and Combo (with AMS lite) SKUs, and an optional cutting/drawing module (blade cutter and pen plotter, 300x300 mm cutting area) that is a separate attachment, not a printer variant. Do not carry A1 or A1 mini figures across: the A2L is a different, much larger machine at 12.8 kg[1][4]Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][5]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger - Tom's Hardware's assembly description has the heatbed bolting to a Y-carriage inside the gantry frame[4]CoreXY[3]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot published in the spec sheet; no teardown source found that documents the Z drive[1]2 mm lead Z screw with an anti-backlash nut[2]
Stepper motors (frame size, step angle, brand if known)Not documentedFOC closed-loop stepper motors[3]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim)[1]800 mm/s (manufacturer claim, maximum)[3]
Max acceleration (claimed, mm/s²)10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1]30,000 mm/s2 (manufacturer claim, maximum)[3]
Max volumetric flow claimed (mm³/s)28 mm3/s claimed, measured by Bambu on a 150 mm round single-wall model in Bambu PLA Basic at 220 C - note this test uses PLA, unlike the ABS-based figures Bambu quotes for its enclosed machines, so it is not directly comparable[1]40 mm3/s rated flow (manufacturer claim)[3]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaper listed as a feature[3]
Extruder
Type (direct drive / bowden) & design nameDirect drive with a servo extruder motor and hardened-steel extruder gears; built-in filament cutter[1]Direct drive, dual hardened-steel gears, 8.9:1 reduction[3]
Gear ratio & drive gear materialNot documented8.9:1; drive gears hardened steel[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Stainless-steel nozzle; 0.2/0.4/0.6/0.8 mm supported. Bambu's A2L sheet does not state whether the hotend is all-metal[1]Multi-metal hotend with a ceramic heater and a 0.4 mm bimetal nozzle; ceramic throat[3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]<=370 °C claimed[2][3]
Heated Bed & Surface
Max bed temp claimed AND firmware limit80 C max heatbed temperature[1]<=120 °C claimed on a 390 x 390 mm bed QIDI markets as ultra-uniform (no thermal imaging published)[2][3]

Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling with automatic Z: Tom's Hardware confirms the nozzle is used as the probe and the machine can re-check level before each print[4]Automatic levelling; probe technology not named by QIDI[3]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry, tangle sensor and clumping detection[1]Filament run-out sensor and filament tangle detection (tangle mechanism not described), plus a filament cutter[3]

Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery listed; mechanism not published[3]
Materials Support
Officially supported filament listSuitable: PLA, PETG, TPU, PVA. PLA-CF and PETG-CF suitable only after fitting a hardened-steel nozzle. ABS, ASA, PA, PC and PET are listed as not recommended on the compare page[1][8]PLA, ABS, ASA, PETG, TPU, PA, PC, and glass- and carbon-fibre-filled polymers[3]
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.

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 (27 June 2026)[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.
