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]Voron 2.4, current revision R2, kits shipping as Rev D and Rev D+. Sold as "Voron 2.4 R2 (Rev D+) 3D Printer Kit by LDO"[2][3]
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[4][5]Not documented
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]$1,399.99 for the LDO Rev D+ kit at Fabreeko (300 mm and 350 mm are the same price), on pre-order with a mid-September estimate, checked Aug 2026. Fabreeko's live feed shows the base 2.4 kit listing at $1,299.99 and available. 3DJake lists an LDO 350 RevD kit but will not ship to the US[2][8][9]
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][10][11][12]Sizes 250, 300 and 350 mm; LDO ships Rev D and Rev D+. Colours black, space grey, blue. Do not confuse with the Trident: the 2.4 lifts the whole gantry on four belted Z motors, the Trident lifts the bed on three screws. The Rev D+ kit includes a Raspberry Pi 4B; the older 3DJake-listed RevD kit explicitly does not include a Pi[2][3][9][13]
Market position: superseded?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 usable180 x 180 x 180 mm (manufacturer figure)[1]300 x 300 x 300 mm or 350 x 350 x 350 mm. Sortable value is the 350 mm kit[2][3][9]
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][4]Not documented
Net weight (kg)5.5 kg net[1]Not documented
Frame construction & materialSteel plus extruded aluminium chassis[1]Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[3][9]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Enclosed by the supplied panel set. A Nevermore Micro V5 internal circulation filter is included in the LDO kit[9]
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[11]CoreXY on linear rails, with a belted flying gantry on four Z motors[3][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[11]Not documented
Y-axis guide typeHorizontal linear guide rail carrying the print platform, belt-driven in Y[11]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashSingle 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[11][12]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedLDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers, ready for 48 V upgrades[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)[1]Not documented
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 nameDirect drive with hardened-steel extruder gears; toolhead also holds the cutter unit, filament hub and filament sensor[1][11]Clockwork 2 with a Bondtech BMG / Integrated Drive Gear Assembly, in a Stealthburner toolhead[2][3][9]
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][11]E3D Revo Voron (24 V), all-metal, high-flow variant in the Rev D+ kit, with a 60 W heater; upgradeable to a Phaetus Rapido HF for $9.99[2][3][9]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]Not documented
Heater cartridge power (W)Not documented60 W (E3D Revo High Flow heater)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit80 C max build-plate temperature - the lowest of the current Bambu range, and the reason ABS/ASA are listed as not recommended[1][11]Not documented
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1]Cast 5083 aluminium plate with a magnetic base and a powder-coated PEI sheet; LDO silicone bed heater with edge-to-edge heating[3][2][9]
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[4][11]Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[2][3]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry and filament-tangle sensor[1]Not documented
Multi-material/multi-color capability or official upgrade pathOptional 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 designOne custom 5015 centrifugal part-cooling fan with two opposing outlets; closed-loop control. A separate MC board cooling fan is also fitted[1][11]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]LDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[3][2][9]
Total rated power draw100-240 VAC 50/60 Hz; max power 150 W for the whole machine. 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[14]Klipper, hosted on a Raspberry Pi 4B (included in the Fabreeko Rev D+ kit, not in the older 3DJake RevD kit)[2][3][9]
Connectivity, UI & Camera
Display: size, type, touch?2.4-inch 320x240 IPS touchscreen[1]4.3-inch touchscreen included in the LDO kit[9]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Bambu Handy app and Bambu Studio PC application[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz only (802.11 b/g/n), Bambu-Bus, microSD card. No Ethernet, no USB host[1]Not documented
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in low-rate camera, up to 1080p, timelapse supported[1]Not documented
LED chamber/toolhead lightingNot documentedCOB LED strips included[2][9]
Calibration Routines & QoL
Assembly level & time from unbox to first printArrives mostly pre-assembled - only the filament wiper, spool holder and Bowden tubes to fit[4]Self-assembly kit; some parts must be printed by the user, and the LDO kit supplies pre-cut, pre-crimped cables and a heat-set insert soldering tip[9]
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET and fibre-reinforced polymers[1]Not documented
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][15]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[16]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 (13 October 2023)[4]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.
