| Property | Bambu Lab A2LBEDSLINGER | Formlabs Form 4LRESIN |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Formlabs |
| Class | BEDSLINGER | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A2L[1] | Formlabs Form 4L[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] | Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 320 x 325 mm (manufacturer figure)[1] | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 544 x 529 x 505 mm[1] | 664 x 528 x 794 mm[2] |
| Net weight (kg) | 12.8 kg net[1] | 58.5 kg[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] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[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] | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[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] | Not documented |
| Max acceleration (claimed, mm/s²) | 10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate included; Engineering Plate and Cool Plate SuperTack also supported[1] | Not documented |
| 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 | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 9 A, 50/60 Hz, 900 W[2] |
| Total rated power draw | Not documented | 900 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] | Proprietary; print preparation is PreForm[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 240x320 touchscreen[1] | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[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] | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[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 |
| 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] | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[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 | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XY dimensional tolerance +/-0.15% — a manufacturer specification[2] |
| 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 |
| Resin & MSLA | ||
| Masking LCD | Not documented | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[2] |
| Light source | Not documented | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[2] |
| Layer height range | Not documented | 25-200 um[2] |
| Resin vat & feeding | Not documented | Two next-generation resin cartridges. No vat capacity published[2] |
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.
