Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab A2L[1]QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[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]Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[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]$649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[2][3]
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]Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[3][2]
Market position: superseded? successor announced?Not documentedSuperseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[7][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable330 x 320 x 325 mm (manufacturer figure)[1]305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)544 x 529 x 505 mm[1]505 x 487 x 550 mm[5]
Net weight (kg)12.8 kg net[1]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5]
Frame construction & materialAluminium and steel chassis with a plastic outer frame; Tom's Hardware describes a triangular gantry frame the base drops into[1]Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][5]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[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[5]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot published in the spec sheet; no teardown source found that documents the Z drive[1]Dual independent Z motors on 10 mm linear shafts and screws[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim)[1]600 mm/s (manufacturer claim, tool-head maximum)[5]
Max acceleration (claimed, mm/s²)10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1]<=20,000 mm/s2 (manufacturer claim)[5]
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]Not documented
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 with hardened steel dual gears, 1.75 mm filament[2][5]
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]Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][5]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]<=370 °C claimed. No firmware max_temp verified for this model[2][5]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit80 C max heatbed temperature[1]Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][5]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate included; Engineering Plate and Cool Plate SuperTack also supported[1]6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][5]
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]Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][5]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry, tangle sensor and clumping detection[1]Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5]
Multi-material/multi-color capability or official upgrade pathNot documentedQIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3]
