|---|---|---|
| Identity | ||
| Brand | Bambu Lab | ELEGOO |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A1 mini. Store title: "Bambu Lab A1 mini 3D Printer"[1] | ELEGOO Centauri 2 (page title "Elegoo Centauri 2 | High-Speed CoreXY 3D Printer")[2] |
| Release date (announcement and actual shipping) | Shipped in the second half of 2023; Tom's Hardware published its A1 mini review on 13 October 2023, ahead of the full-size A1 review of 14 December 2023[3][4] | Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[5] |
| Street price (USD; dated snapshot per entry) | From $219.00 (base A1 mini) on the Bambu Lab US store, Aug 2026, during an advertised Back-to-School sale; the product page lists A1 mini and A1 mini Combo variants[6][7] | $279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two SKUs: A1 mini and A1 mini Combo (adds the AMS lite). Distinguish from the full-size A1 by build volume (180 vs 256 mm cube), bed ceiling (80 vs 100 C), screen (2.4 vs 3.5 inch), Z drive (single leadscrew with a coupling vs dual leadscrews belt-synced) and weight (5.5 vs 8.3 kg)[1][8][9][10] | Sold both bare and as a Centauri 2 Combo. The Combo is the one with multicolour: 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection are all listed Yes for the Combo and dash for the bare machine, and the Combo body measures 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting, air filter and the smart exhaust grille are optional expansions on both. Distinct from the Centauri Carbon line, which is enclosed and takes carbon-fibre filament[2][11] |
| Market position: superseded? successor announced? | Still the entry model in the Bambu Lab US store line-up in Aug 2026 and the cheapest machine listed[6] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 180 mm (manufacturer figure)[1] | 256 x 256 x 256 mm; printing platform 260 x 260 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 347 x 315 x 365 mm (Bambu tech specs; Tom's Hardware prints 347 x 314 x 365 mm)[1][3] | 398 x 404 x 490 mm for the bare Centauri 2 (the Combo is 500 x 480 x 586 mm)[2] |
| Net weight (kg) | 5.5 kg net[1] | 13.7 kg net, 17.5 kg gross (bare machine; the Combo is 15.5 kg net, 19 kg gross)[2] |
| Frame construction & material | Steel plus extruded aluminium chassis[1] | Rigid aluminium frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bed-slinger: toolhead on an X guide rail and crossbeam, print platform moving in Y on a guide rail, toolhead carried in Z[9] | CoreXY with dual 4260 stepper motors driving X and Y independently[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Horizontal linear guide rail with the printhead on a sliding block; rail size not published[9] | Not documented |
| Y-axis guide type | Horizontal linear guide rail carrying the print platform, belt-driven in Y[9] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Single leadscrew with nut, coupling and stepper motor - the motor drives the leadscrew directly through the coupling. This is the clearest hardware difference from the A1, which uses two leadscrews synchronised by a belt[9][10] | Three lead screws with three linear guide rods[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)"; no driver part number published[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s or less, with 250 mm/s given as the recommended speed[2] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[2] |
| Max volumetric flow claimed (mm³/s) | 28 mm3/s claimed on a 150x150 mm single-wall model in Bambu ABS at 280 C - note this is the ABS figure quoted for a machine whose own spec sheet lists ABS as not recommended[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel extruder gears; toolhead also holds the cutter unit, filament hub and filament sensor[1][9] | Dual-gear direct extruder with one fan[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal integrated hotend (nozzle plus heatsink in one unit), quick-swap; stainless-steel nozzle, 0.4 mm included, 0.2/0.6/0.8 mm optional[1][9] | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 350 C claimed max nozzle temperature - higher than the enclosed Centauri Carbon's 320 C, even though ELEGOO lists ABS, ASA, PET, PETG-CF, PA and PC as not recommended on this machine[2][11] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 C max build-plate temperature - the lowest of the current Bambu range, and the reason ABS/ASA are listed as not recommended[1][9] | 110 C max heated bed temperature at 25 C ambient[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1] | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch automatic bed levelling and automatic Z-offset; Tom's Hardware confirms the nozzle itself is the probe[3][9] | 121-point auto-levelling plus partial bed levelling, with full-auto calibration[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, filament odometry and filament-tangle sensor[1] | Filament run-out sensor, clog detection, auto filament unloading, fan self-check, part-cooling-fan drop detection and power-loss recovery[2] |
| Multi-material/multi-color capability or official upgrade path | Optional AMS lite (A1 mini Combo); AMS / AMS 2 Pro / AMS HT need an AMS HUB (SA013) accessory[7] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One custom 5015 centrifugal part-cooling fan with two opposing outlets; closed-loop control. A separate MC board cooling fan is also fitted[1][9] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Bambu names the motion controller as a dual-core Cortex-M4; no board model or chip markings published[1] | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[2] |
| Total rated power draw | 100-240 VAC 50/60 Hz; max power 150 W for the whole machine. Bed heater wattage is not published separately[1] | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[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[12] | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.4-inch 320x240 IPS touchscreen[1] | 5-inch colour capacitive touch screen - larger than the 4.3-inch panel on the Centauri Carbon[2][11] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Bambu Handy app and Bambu Studio PC application[1] | Colour touch UI; input formats STL, OBJ, 3MF and STEP[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz only (802.11 b/g/n), Bambu-Bus, microSD card. No Ethernet, no USB host[1] | USB and Wi-Fi[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in low-rate camera, up to 1080p, timelapse supported[1] | No camera as standard - listed as an optional expansion, as are LED lighting and the air filter[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Arrives mostly pre-assembled - only the filament wiper, spool holder and Bowden tubes to fit[3] | Not documented |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET and fibre-reinforced polymers[1] | Ideal: PLA, PETG, PLA-CF, TPU. Explicitly not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Manufacturer claim only: the US store page claims "49dB Whisper-Quiet Operation" - the identical sentence appears on the A1 page, so treat it as line-level marketing copy rather than a per-model measurement. No independent dB measurement with a stated distance was found[7][13] | Not documented |
| 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[14] | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[15] |
| 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 (13 October 2023)[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.
