| Property | Bambu Lab A1 miniBEDSLINGER | FlashForge Guider 3 UltraINDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | FlashForge |
| Class | BEDSLINGER | INDUSTRIAL |
| 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] | Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[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] | 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[5][6] | $2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[2] |
| 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][7][8][9] | Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[2][10][11] |
| Market position: superseded?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[5] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 180 mm (manufacturer figure)[1] | 330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[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] | 635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[2] |
| Net weight (kg) | 5.5 kg net[1] | 70 kg net, 86 kg gross[2] |
| Frame construction & material | Steel plus extruded aluminium chassis[1] | Enclosed professional chassis; FlashForge describes a lightweight, stable structure for high-speed operation[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Closed design with an air filter fitted[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[8] | CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[12][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[8] | Not documented |
| Y-axis guide type | Horizontal linear guide rail carrying the print platform, belt-driven in Y[8] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Single 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[8][9] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[2] |
| Max acceleration (claimed, mm/s²) | 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20,000 mm/s2 maximum (manufacturer claim)[2] |
| 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 documented | Active vibration compensation, which FlashForge says was enhanced for this model. Implementation not named[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel extruder gears; toolhead also holds the cutter unit, filament hub and filament sensor[1][8] | Two extruders[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][8] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 350 °C maximum extruder temperature (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm default; 0.6 and 0.8 mm optional[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 C max build-plate temperature - the lowest of the current Bambu range, and the reason ABS/ASA are listed as not recommended[1][8] | 120 °C bed setting supported (manufacturer figure)[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Smooth PEI and Dual-Texture PEI plates also compatible[1] | Replaceable flexible steel-plate platform, magnetic. No glass bed[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][8] | Full-auto one-click levelling; probe technology not named[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, filament odometry and filament-tangle sensor[1] | Filament run-out reminder[2] |
| Multi-material/multi-color capability or official upgrade path | Optional AMS lite (A1 mini Combo); AMS / AMS 2 Pro / AMS HT need an AMS HUB (SA013) accessory[6] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One custom 5015 centrifugal part-cooling fan with two opposing outlets; closed-loop control. A separate MC board cooling fan is also fitted[1][8] | Not documented |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | Air filter fitted; filter media not specified in the FlashForge table[2] |
| 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] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | AC 100-240 V, 50/60 Hz[2] |
| Total rated power draw | 100-240 VAC 50/60 Hz; max power 150 W for the whole machine. Bed heater wattage is not published separately[1] | 850 W maximum[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] | Not named; slicers are Orca-Flashforge and FlashPrint 5, with OrcaSlicer listed as compatible[2] |
| Connectivity, UI & Camera | ||

| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published. Automatic shutdown also supported[2] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA. Not recommended: ABS, ASA, PC, PA, PET and fibre-reinforced polymers[1] | PLA, ABS, HIPS, ASA, PETG, CoPA, PLA-CF, PETG-CF, PAHT-CF, PAHT-GF, PET-CF, PET-GF, PA12-CF, PA-CF, PA-GF, NexPA-CF25[2] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | CE, FCC, RoHS (as printed in FlashForge's own spec table)[2] |
| 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[6][14] | 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[15] | 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)[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.
