People are starting to think differently about entry-level 3D printers thanks to the Bambu Lab A1 mini. This small machine boasts features typically found in much more expensive models, such as fast print speeds and the ability to print in multiple colors. It’s especially appealing if you’re new to 3D printing, a hobbyist, or don’t have a lot of space but still want something that works well and is easy to use. The A1 mini is distinct from other printers because it combines Bambu Lab’s renowned speed with AMS multi-color printing, all at a surprisingly low price.
This review article explains why the A1 Mini is an excellent choice for anyone seeking to enter the world of 3D printing.
Bambu Lab A1 mini offers ease of use in 3D printing with features once found only in high-end models, making it accessible to beginners.

See What You Can Do With A1 mini




The Out-of-the-Box Experience
The Bambu Lab A1 small is designed to address the primary issue that new users encounter: a complex setup.
Unboxing & Setup:
The process is refreshingly simple and lives up to the claim of being “ready to print in 15 minutes.” A minimal number of parts and clear instructions guide you through a quick, foolproof assembly. It’s a true plug-and-play experience.

First Impressions:
The A1 mini makes an immediate impression with its physical design. Its clean, cantilever structure gives it a compact aesthetic, while its incredibly small footprint—roughly the size of an A4 sheet of paper- makes it an ideal choice for a desk or a small workshop. Despite its size, the overall build quality feels solid and sturdy, a promising sign that this little machine is more than capable of handling high-speed printing.
Highlight Overview
Core Features & Performance
Don’t let the “mini” in the name fool you—the Bambu Lab A1 mini is a powerhouse of performance and intelligence.
Intelligent Automation:
Full-Auto Calibration:
The A1 mini features a seamless, one-touch calibration system that automatically handles Z-offset and bed leveling. There’s no need for manual tweaking—just press a button and the printer takes care of the rest, making setup and maintenance effortless.
Active Flow Rate Compensation:
This smart feature enables the printer to automatically adjust filament flow in real-time. The result is consistent extrusion and reliable print quality, even when switching between different materials or print speeds.

High-Speed Capabilities
The A1 mini is an absolute speed demon. Its core engineering enables it to reach a blazing maximum print speed of 500 mm/s, significantly reducing print times. What’s truly impressive is that it achieves this speed without sacrificing quality. The printer is designed to actively minimize vibrations, which means you get crisp, clean models that are free from the tell-tale “ringing” that plagues other fast machines.
Print Quality & User Experience:
When you pull a print off the bed, the results speak for themselves. The A1 mini consistently produces prints with remarkably clean layers and sharp details. Just as important as the quality of the final product, the entire printing process is incredibly quiet. This makes the A1 mini a pleasant machine to have on your desk, allowing you to focus on your work without being distracted by the noise of a printer.


The Multi-Color Advantage (AMS Lite)
The Bambu Lab A1 mini truly sets itself apart with a feature that was previously unheard of in this price category: multi-color printing. This is all thanks to the AMS Lite, a brilliant piece of engineering that makes the process feel incredibly accessible.
Introducing the AMS Lite:
The Automatic Material System (AMS) Lite is a cleverly designed filament handling system that connects directly to the printer. Its four-spool capacity is not just for show; it’s a true game-changer that allows for seamless multi-color printing. The system’s design is both functional and user-friendly, featuring visible spools that allow you to manage your filament inventory at a glance.

Multi-Color Printing:
The AMS Lite enables printing with up to four different colors or materials in a single job. The system intelligently handles all filament switching, retracts one spool, and loads the next with precision. Consequently, what once required hours of manual intervention is now an automated process, enabling even beginners to create stunning, complex prints with multiple colors.
Filament & Material Management:
Beyond just color, the AMS Lite is also a smart material manager. It keeps your spools protected from dust and, more importantly, from moisture, ensuring your filament remains in optimal condition for printing. However, it’s crucial to address the one common trade-off with this technology: filament waste. The process of purging and changing colors results in some material being purged into a waste tower. While this is an unavoidable part of the process, the incredible convenience and creative freedom it provides more than justifies the small amount of discarded material. Software and Ecosystem

Multi-Color Printing For Everyone
The all-new AMS Lite is elegant and reliable, making multi-color 3D printing accessible to everyone.


Strengths and Weaknesses
The Bambu Lab A1 mini is an outstanding machine, but like any piece of technology, it has its own set of strengths and weaknesses. Understanding them is key to deciding if it’s the right printer for you.
| Strengths | Weaknesses |
|---|---|
|
Delivers one of the best all-around experiences for beginners Offers high-speed, high-quality printing right out of the box Makes multi-color printing accessible and easy to use Excellent software integration with Bambu Studio and mobile app |
The 180 mm³ build volume limits the size of projects you can print Open-frame design and lower bed temperature restrict compatibility with high-temp, warping-prone materials like ABS and ASA The AMS Lite system creates some filament waste during color changes, which is a common trade-off for multi-color printing |

Does the A1 mini have built-in memory?
No, the A1 mini does not have built-in memory, so you need to insert a microSD card to initiate printing. The printer comes with a pre-installed 32 GB micro SD card
What is the maximum microSD card size supported?
Booking your dream vacation is simple! Discover how to choose destinations, tailor your itinerary, and finalize your booking with our straightforward process.
Is the regular AMS compatible with the A1 mini?
No, AMS is not compatible with the A1 mini1. To achieve multi-color printing with the A1 mini, you need to use the AMS Lite
Can I print carbon fiber or glass fiber filaments?
The A1 mini comes with a pre-installed 0.4mm stainless steel nozzle, which is not recommended for materials containing carbon fiber or glass fiber (such as PLA-CF/GF and PETG-CF/GF) due to excessive wear. However, if you replace the nozzle with a hardened steel material, you can print CF-based filaments
Why am I experiencing first layer adhesion problems?
What is the recommended ambient temperature?
The recommended ambient temperature for the A1 mini is 10 °C – 30 °C (50°F – 86°F), with humidity levels below 85%.
Does it support power loss recovery?
Yes, after powering on the printer again, you have the option to resume printing after a power loss
How long does initial setup take?
The A1 mini comes pre-assembled, pre-squared, and pre-tuned, requiring only about 20 minutes to set up for your first print.
