|---|---|---|
| Identity | ||
| Brand | Bambu Lab | VzBoT |
| Class | BEDSLINGER | COREXY |
| 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] | VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[2] |
| 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[3][4] | 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[5][6] | $1,360.00 at Mellow, available and shipping from China, checked Aug 2026[2] |
| 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][4][6] | Ordered by colour (black or silver) and mains voltage (110 V or 220 V). Mellow describes the kit as a test version that still requires the buyer to print some components, and the 5-inch DSI screen requires a host computer that supports DSI — neither is included[2] |
| Market position: superseded?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[5][7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm (manufacturer figure)[1] | 330 x 330 x 400 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][4] | 530 x 500 x 720 mm body dimensions[2] |
| Net weight (kg) | 8.3 kg net[1] | 31 kg net, 36 kg gross[2] |
| Frame construction & material | Steel plus extruded aluminium chassis; Bambu markets all-metal rails and a cover-protected drive system[1][8] | CNC-machined all-metal frame with carbon-rod components[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure or door; no official enclosure is sold for the A1[1] | Not documented |
| 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[9][8] | CoreXY in an AWD (all-wheel drive) arrangement — two motors on X and two on Y, four in total for the XY plane, each on its own external driver[2] |
| 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[9] | LDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[2] |
| Y-axis guide type | Linear rail: heatbed mounted on a guide-rail slider, belt-driven in Y[9] | 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[9] | 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[9] | 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[9] | Four external TMC5160 drivers for the LDO XY motors[2] |
| 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][4] | 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][9] | Lightweight all-metal direct drive with a twill drive wheel[2] |
| 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][8][9] | VZ High Speed hotend[2] |
| 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][9] | 120 °C maximum bed temperature (manufacturer claim)[2] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 750 W silicone bed heater on an 8 mm aluminium plate[2] |
| 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] | 8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[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[9][4] | Not documented |
| 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][9] | 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)[6] | 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][9] | 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] | 32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[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[10] | Klipper or RepRapFirmware[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 320x240 IPS touchscreen[1] | 5-inch DSI display; requires a compatible host computer, which is not included[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][8] | 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] | Not documented |
| 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][8] | 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[4] | Self-assembly kit; some parts must be printed by the buyer[2] |
| 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] | Not documented |
| Safety | ||
| 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[3][6] | 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"[8][6][4] | 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[11] | 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)[4] | Not documented |
