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]Prusa CORE One L+[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]The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[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]$1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[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]Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[2][9][8]
Market position: superseded?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 330 mm, which Prusa states as 29.7 litres[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]469 x 521 x 635 mm[2]
Net weight (kg)5.5 kg net[1]21.9 kg (48.3 lb)[2]
Frame construction & materialSteel plus extruded aluminium chassis[1]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedActive convection chamber heating, maximum 60 C (manufacturer figure)[2]
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 - stated in Prusa's CORE One+ comparison table[9]
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 documentedTrinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[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
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput Shaper and Phase Stepping with an integrated accelerometer[2]
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]Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox[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][11]Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[2][5]
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]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1]Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[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][11]High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry and filament-tangle sensor[1]Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2]
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]Custom 32-bit xBuddy mainboard with an STM32 processor[2]
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]Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[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[13]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[14][15]
Connectivity, UI & Camera
Display: size, type, touch?2.4-inch 320x240 IPS touchscreen[1]3.5-inch 65k-colour touch screen (CORE One family)[9]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Bambu Handy app and Bambu Studio PC application[1]On-device touch UI with Prusa Connect and Prusa mobile app remote control[9]
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]Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[2]
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
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[3]Not documented
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET and fibre-reinforced polymers[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedOpen-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[16][14]
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][17]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[18]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[19][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.
