| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A2L[1] | Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[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 documented |
| 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[5] | $649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (Aug 2026)[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] | Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 320 x 325 mm (manufacturer figure)[1] | 211.68 x 118.37 x 220 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 544 x 529 x 505 mm[1] | 327.4 x 329.2 x 548 mm[2] |
| Net weight (kg) | 12.8 kg net[1] | Not documented |
| 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] | Metal housing with a flip-up cover and a drip guard[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[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[4] | MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[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[4] | Automatic levelling, plus intelligent mechanical sensor alarms[2] |
| 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 V, 50/60 Hz, 24 V 6 A[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[6] | Elegoo EL3D-4.0 system. Slicer is CHITUBOX[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 240x320 touchscreen[1] | 4-inch capacitive touchscreen (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] | USB and Wi-Fi, with WLAN file transfer[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] | AI camera, 1920 x 1080[2] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | Not documented | AI camera with print-failure detection[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][7] | 405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[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[8] | 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)[4] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Not documented | 10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[2][3] |
| Light source | Not documented | COB light source with a Fresnel collimating lens[2] |
| Light uniformity & intensity | Not documented | Light energy at the plate quoted as 5 mW/cm2, i.e. 5000 uW/cm2 (manufacturer claim, attributed to the tilt-release and Fresnel optics). No uniformity percentage published and no independent measurement[2] |
| Vertical print speedmm/h | Not documented | Up to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2] |
| Release film | Not documented | PFA release film. No rated life published[2] |
| LCD life & replaceability | Not documented | Masking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[2] |
| Resin vat & feeding | Not documented | Replaceable resin vat with a dual pour spout and a drip guard. Heated tank with automatic temperature measurement: Elegoo states resin reaches 25 C in 26 minutes from a 5 C ambient at 50% humidity (manufacturer figure). Capacity not published; no auto-refill[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.
