| Property | Bambu Lab A2LBEDSLINGER | Positron V3.2COREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Positron3D |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A2L[1] | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[2] |
| 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[3] | Not documented |
| Launch MSRP (USD) | $469 standalone, $569 Combo at launch[3] | Not documented |
| Street price (USD; dated snapshot per entry) | From $469.00 on the Bambu Lab US store, Aug 2026[4] | Not documented |
| 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][3] | The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 320 x 325 mm (manufacturer figure)[1] | 180 x 180 x 165 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 544 x 529 x 505 mm[1] | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[2] |
| Net weight (kg) | 12.8 kg net[1] | 3 kg net; 5.5 kg with the hard case[2] |
| Frame construction & material | Aluminium and steel chassis with a plastic outer frame; Tom's Hardware describes a triangular gantry frame the base drops into[1] | Folding frame designed to fit in a filament box; supplied with a black hard case[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame[2] |
| 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[3] | CoreXY, inverted — the machine prints upside down[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not published in the spec sheet; no teardown source found that documents the Z drive[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | 250 mm/s maximum print speed (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | 10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 8,000 mm/s2 (manufacturer claim)[2] |
| 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 name | Direct drive with a servo extruder motor and hardened-steel extruder gears; built-in filament cutter[1] | Bowden-style, single extrusion[2] |
| 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] | PS plated-copper nozzle, 0.4 mm[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 260 °C maximum (manufacturer claim)[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Plated copper[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 C max heatbed temperature[1] | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate included; Engineering Plate and Cool Plate SuperTack also supported[1] | Heated removable ITO glass bed[2] |
| 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[3] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, filament odometry, tangle sensor and clumping detection[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan and hotend cooling fan, both closed-loop controlled. No auxiliary part-cooling fan and no chamber fan[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | LDO Positron mainboard[2] |
| PSU (brand, wattage, rail voltage) | Not documented | DC 24 V, 200 W[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[5] | Klipper[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 240x320 touchscreen[1] | 3.5-inch LCD touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus mobile app and PC app[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | 2.4 GHz Wi-Fi only (802.11 b/g/n), Bambu-Bus, microSD card. Ethernet not available[1] | Wi-Fi, USB, Ethernet[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in low-frame-rate camera, up to 1080p, timelapse supported[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit, manufactured in China[2] |
| Materials Support | ||
| Officially supported filament list | Suitable: 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][6] | PLA and PETG only, per the manufacturer[2] |
| 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[7] | Not documented |
| 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)[3] | 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.
