| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A1. Store title: "Bambu Lab A1 3D Printer"; spec page header "Bambu Lab A1 - Technical Specifications"[1] | ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-monochrome-lcd-resin-3d-printer[2][3][4] |
| Release date (announcement and actual shipping) | 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[5][6] | Not documented |
| Street price (USD; dated snapshot per entry) | 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[7][8] | $179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[3][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][6][8] | Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[2][9][3][4] |
| Market position: superseded? successor announced? | Still sold new in Aug 2026 alongside the newer and larger A2L ($469 base), which Bambu positions as the mega-size A-series machine[7][10] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm (manufacturer figure)[1] | 143.43 x 89.6 x 150 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 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[1][6] | 230 x 230 x 433.5 mm[2] |
| Net weight (kg) | 8.3 kg net[1] | Approximately 6.6 kg[2] |
| Frame construction & material | Steel plus extruded aluminium chassis; Bambu markets all-metal rails and a cover-protected drive system[1][11] | Metal frame with adjustable foot pads[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure or door; no official enclosure is sold for the A1[1] | Open-frame MSLA with a removable UV-blocking cover[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | 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] | MSLA — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[2][9] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Linear rail: "a high-precision linear rail and a beam", toolhead on a linear guide slider (Bambu wiki). Rail size not published[12] | Not documented |
| Y-axis guide type | Linear rail: heatbed mounted on a guide-rail slider, belt-driven in Y[12] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | 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] | Not documented |
| Belts (type, width, e.g. Gates?) | Three adjustable belt tensioners (X, Y, Z); a Belt Tension Monitor watches tension and reports out-of-range belts[12] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | 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] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 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[1][6] | Not documented |
| Max volumetric flow claimed (mm³/s) | 28 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive, hardened-steel extruder gears, integrated in the toolhead with a filament cutter and filament hub[1][12] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 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[1][11][12] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature; firmware limit not published[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max build-plate temperature (both the spec sheet and the wiki give 100 C)[1][12] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate included; Bambu Cool Plate, High Temperature Plate and Dual-Texture PEI Plate also compatible[1] | Laser-engraved build plate with a quick-release design[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 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][6] | Automatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | 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[1][12] | Not documented |
| Multi-material/multi-color capability or official upgrade path | 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)[8] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One custom 5015 centrifugal part-cooling fan with two opposing air outlets aimed at the nozzle; closed-loop (RPM-feedback) control[1][12] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | 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[1] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 V, 50/60 Hz, 24 V 3 A[2] |
| Total rated power draw | 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[1] | Not documented |
| 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[13] | Not named by Elegoo. Supported slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 320x240 IPS touchscreen[1] | 3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen UI plus Bambu Handy mobile app and Bambu Studio PC application; Bambu describes the on-device UI as a simplified guided touchscreen system[1][11] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | 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[1] | USB only — no Wi-Fi on this model[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | 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)[1][11] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | About 95% pre-assembled; a handful of screws attach the gantry to the base, then the filament wiper and spool holder[6] | Not documented |
| Materials Support | ||
| Officially supported filament list | 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[1] | 405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[2] |
| Safety | ||
| Firmware safety limits (max temp cutoffs — exact values) | Not documented | Intelligent overheating protection stops printing above 80 °C[2] |
| Known safety incidents / recalls / fire reports (with sources) | 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[5][8] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 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][8][6] | 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] | 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 (14 December 2023)[6] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Not documented | 6.6-inch 4K monochrome masking LCD, 4098 x 2560 px, XY pixel pitch 35 x 35 um (manufacturer specification)[2][4] |
| Light source | Not documented | COB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[2] |
| Vertical print speedmm/h | Not documented | 70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2] |
| Release film | Not documented | PFA film with a non-stick surface. No rated life published[2] |
| Resin vat & feeding | Not documented | Replaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[2] |
| Fume extraction | Not documented | None fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[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.
