| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 3 Max[1] | Bambu Lab A1. Store title: "Bambu Lab A1 3D Printer"; spec page header "Bambu Lab A1 - Technical Specifications"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 19 February 2025 (Shopify publish date)[3] | Announced and first shipped in the northern autumn/winter of 2023. Bambu Lab's own recall notice states A1 units were supplied from 1 December 2023; Tom's Hardware published its A1 review on 14 December 2023, so retail units were in reviewers' hands by then[4][5] |
| Street price (USD; dated snapshot per entry) | $429.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $699.00 ($493.00 for the EU plug variant)[3] | From $299.00 (base A1) on the Bambu Lab US store, Aug 2026, during an advertised Back-to-School sale; the A1 product page shows $399.00 with the A1 Combo (A1 + AMS lite) swatch selected[6][7] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same 420 x 420 x 500 mm build volume as the older Kobra 2 Max, so build volume will not tell them apart - but the Kobra 3 Max is faster (600 mm/s claimed against 500), runs Kobra OS with multi-colour support and a 4.3-inch touchscreen, and is lighter at 19 kg against 21 kg. Its acceleration ceiling is 10000 mm/s2, half the 20000 mm/s2 of the smaller Kobra 3 - a difference the marketing does not lead with[1][8][9] | Two SKUs on one product page: A1 (printer only) and A1 Combo (adds the AMS lite four-spool unit); the printer hardware is identical. Do NOT confuse with the A1 mini (180 mm cube, single Z leadscrew, 80 C bed, 2.4-in screen) or the newer A2L (330x320x325 mm). Contamination example found in the wild: Tom's Hardware's A1 review spec box prints a 2.4-inch screen and a 385x410x430 mm footprint (both A1 mini figures) and titles a section "Included in the box: Bambu Lab A1 Mini", while Bambu's own A1 spec sheet says 3.5-inch screen and 465x410x430 mm[2][5][7] |
| Market position: superseded? successor announced? | Not documented | Still sold new in Aug 2026 alongside the newer and larger A2L ($469 base), which Bambu positions as the mega-size A-series machine[6][10] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 500 mm, which Anycubic states as 88 L[1] | 256 x 256 x 256 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 706 x 640 x 753 mm[1] | 465 x 410 x 430 mm per Bambu's own tech-spec sheet. Tom's Hardware's spec box prints 385 x 410 x 430 mm for the same machine - that is the A1 mini's width, treat Bambu's figure as authoritative. Add clearance behind for Y-axis bed travel and above for the spool[2][5] |
| Net weight (kg) | 19 kg[1] | 8.3 kg net[2] |
| Frame construction & material | Not documented | Steel plus extruded aluminium chassis; Bambu markets all-metal rails and a cover-protected drive system[2][11] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame, no enclosure or door; no official enclosure is sold for the A1[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic's table gives the construction as "Gantry System" - a bed-slinger, with dual Y-axis motors added to stop layer misalignment on the large moving bed[1] | Cartesian bed-slinger: toolhead moves in X on the gantry beam, heatbed moves in Y, gantry moves in Z. Bambu's own wiki calls it a Cartesian coordinate motion system; Bambu's marketing page describes it as a "Bed Slinger with CoreXY Speed", which is a comparison, not a kinematic claim[12][11] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rail: "a high-precision linear rail and a beam", toolhead on a linear guide slider (Bambu wiki). Rail size not published[12] |
| Y-axis guide type | Not documented | Linear rail: heatbed mounted on a guide-rail slider, belt-driven in Y[12] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual linear rods plus dual leadscrews with nuts, both leadscrews driven from one stepper through a synchronous belt with a quick tensioner and a tension-detection algorithm[12] |
| Belts (type, width, e.g. Gates?) | Semi-automatic belt tensioning, which Anycubic pairs with motor anti-skip[1] | Three adjustable belt tensioners (X, Y, Z); a Belt Tension Monitor watches tension and reports out-of-range belts[12] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Not published. Bambu's wiki says only that the mainboard "incorporates stepper motor drivers"; no driver part number is given and no teardown source was found that names one[12] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2] |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][9] | 10000 mm/s2 max toolhead acceleration (manufacturer claim). Tom's Hardware notes the moving-bed mass is why the A1 does not reach the P1S/X1 20000 mm/s2 figure[2][5] |
| Max volumetric flow claimed (mm³/s) | Not documented | 28 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion") with a quick-release hotend[1] | Direct drive, hardened-steel extruder gears, integrated in the toolhead with a filament cutter and filament hub[2][12] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 300 C quick-release hotend with an aerospace-grade ceramic composite throat tube; 0.4 mm standard nozzle, expandable to 0.6 and 0.8 mm[1] | All-metal integrated hotend (nozzle and heatsink combined in one unit) with a quick-swap clip - Bambu markets it as popping in and out with one clip. Stainless-steel nozzle, 0.4 mm included, 0.2/0.6/0.8 mm optional[2][11][12] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature[1] | 300 C claimed max hot-end temperature; firmware limit not published[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 90 C maximum hotbed temperature on a PEI spring steel plate - 20 C below the smaller Kobra 3[1][9] | 100 C max build-plate temperature (both the spec sheet and the wiki give 100 C)[2][12] |
| Heat-up time to 60°C (measured preferred) | Anycubic claims the ultra-large hotbed heats up in 125 s; no target temperature is stated for that figure and it is a manufacturer claim, not a measurement[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Textured PEI plate included; Bambu Cool Plate, High Temperature Plate and Dual-Texture PEI Plate also compatible[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset and area levelling[1] | Nozzle-touch probing: the hotend carries an eddy-current sensor that detects nozzle-to-bed contact, giving both automatic bed mesh and automatic Z-offset with no paper method. The same eddy-current sensor doubles as the Y-axis resonance sensor[12][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Yes - filament run-out sensor, plus filament odometry and a filament-tangle sensor. The tangle sensor is a Hall sensor reading a magnet in the toolhead filament hub: excessive feed resistance pulls the hub down, moving the magnet toward the sensor[2][12] |
| Multi-material/multi-color capability or official upgrade path | Supports 4- or 8-colour printing with ACE Pro units[1] | Optional AMS lite (four spools, sold in the A1 Combo); connecting the enclosed-printer AMS / AMS 2 Pro / AMS HT to an A1 additionally requires an AMS HUB accessory (SA013)[7] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | One custom 5015 centrifugal part-cooling fan with two opposing air outlets aimed at the nozzle; closed-loop (RPM-feedback) control[2][12] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Single mainboard carrying a low-power dual-core SoC (with Wi-Fi and Bluetooth basebands and RF), a dual-core MCU and a single-core MCU, plus the stepper drivers. Bambu's spec sheet names the motion controller as a dual-core Cortex-M4. Exact chip markings not published[2] |
| Total rated power draw | Not documented | 100-240 VAC 50/60 Hz; max power 1300 W at 220 V, 350 W at 110 V. Bed heater wattage is not published separately[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS; Anycubic Slicer Next is built on the open-source Orca slicer[1] | 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[13] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 3.5-inch 320x240 IPS touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicer, Anycubic app and USB (print only); AI spaghetti detection and object skip supported[1] | Touchscreen UI plus Bambu Handy mobile app and Bambu Studio PC application; Bambu describes the on-device UI as a simplified guided touchscreen system[2][11] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and USB drive (print only)[1] | Wi-Fi 2.4 GHz only (IEEE 802.11 b/g/n, 2412-2472 MHz), Bambu-Bus for the AMS lite, microSD card slot. No Ethernet, no USB host port[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in low-rate monitoring camera, up to 1080p, timelapse supported; Bambu's marketing calls out a physical lens cover. Frame rate is not stated for the A1 (the P1 series camera is specified at 0.5 fps)[2][11] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | About 95% pre-assembled; a handful of screws attach the gantry to the base, then the filament wiper and spool holder[5] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU (TPU is not compatible with the ACE Pro)[1] | Ideal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET, carbon/glass-fibre reinforced polymers - the machine is open-frame and the bed stops at 100 C[2] |
| Safety | ||
| Known safety incidents / recalls / fire reports (with sources) | Not documented | Recalled in the US in cooperation with the CPSC: A1 units sold before 30 January 2024 (serial numbers with 'A' as the sixth digit) could suffer heatbed cable damage leading to a short circuit, electric shock or fire. 19 reports of damaged cables, one with observed sparking, no injuries. Remedy was refund plus $80 voucher, or heatbed+cable replacement by a trained technician plus $120 voucher. Current production ships a Kevlar-reinforced heatbed cable with thicker insulation and extended strain relief[4][7] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 60 dB or less in standard mode - a manufacturer figure with no distance or method stated; markedly higher than the 46-48 dB Anycubic claims for the Kobra S1 and Kobra 4[1][14][15] | Manufacturer claim only: bambulab.com states "Silent Mode Under 48 dB" with active motor noise cancelling; the US store page for both the A1 and the A1 mini carries identical copy claiming "49dB Whisper-Quiet Operation". No microphone-based independent measurement with a stated distance was found; Tom's Hardware only says it is "much more quiet than the current crop of speed freak machines"[11][7][5] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[16] | 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[17] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Not documented | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (14 December 2023)[5] |
