Bambu Lab A1 Combo vs. Anycubic Kobra 3 Combo (2025): Established System or New Innovation?

Getting started with reliable, multi-color 3D printing has never been easier. In 2025, two main options lead the beginner-friendly "combo" market: the Bambu Lab A1 Combo and the Anycubic Kobra 3 Combo. For newcomers and hobbyists, picking between them is an important choice. It's not just about features; it's about approach and how you work. Do you choose a proven, smooth-running system or try a newcomer with an innovative, everything-in-one design?

This detailed comparison goes beyond just listing features. We will look at the main choice: the A1 Combo's well-developed, tightly-connected multi-color system versus the Kobra 3 Combo's bold ACE Pro unit, which uniquely includes active filament drying. Our goal is to give you a clear guide to help you decide which system works best with your printing goals, without picking a single "winner."

The Multi-Color Heart

Bambu's AMS Lite

Bambu Lab's approach with the AMS Lite focuses on a polished, "it just works" user experience. The system, having been available for some time, is well-tested and known for being very reliable. It represents the standard for user-friendly multi-color printing at this price level.

The user process is designed for simplicity. The AMS Lite is an open-air unit that holds four spools, with separate motors feeding filament through PTFE tubes directly to the print head. Its connection with the A1 printer and the Bambu Studio slicer is nearly perfect. For users of Bambu Lab's own filament, the system's RFID readers automatically detect the material type, color, and remaining amount, loading all needed print settings without any user input. This creates a smooth, almost magical experience from digital model to physical object.

In practice, the system's reputation for consistent, automated filament swaps is well-deserved. The technology and its supporting software have developed, leading to low failure rates and predictable performance. It has become the standard by which other entry-level multi-material systems are measured.

However, this polished simplicity comes with known trade-offs. The most significant is its open-air design, which offers no protection for the filament spools from surrounding humidity or dust. This leads to the second major point: filament drying is a completely separate process. Users must buy a dedicated filament dryer, manually dry their spools, and then load them into the AMS Lite. This adds an extra step and equipment to the workflow. Finally, the system was designed mainly for standard plastic spools, and users with cardboard or oversized spools often need to print adapters or re-spool their filament to ensure reliable operation.

Anycubic's ACE Pro

Anycubic's ACE Pro unit is the challenger's bold move. It is a multi-material system designed from the beginning to address the main weaknesses of the AMS Lite, most notably the issue of filament moisture.

The user workflow more closely resembles Bambu Lab's higher-end, enclosed AMS. The ACE Pro is a sealed box that houses the filament spools, protecting them from dust and, to some extent, surrounding air. It pairs with the Kobra 3 printer and the Anycubic Slicer to manage filament loading and swapping.

The game-changing feature is its built-in active drying capability. This is a huge advantage for anyone printing with more than just standard PLA. Most 3D printing filaments, including PLA, PETG, TPU, ABS, and Nylon, are hygroscopic, meaning they easily absorb moisture from the air. This absorbed water turns to steam in the hotend, causing many print quality issues: excessive stringing, weak and brittle parts, poor layer bonding, and a rough, pitted surface finish.

The ACE Pro's practical benefit is significant. It allows a user to actively dry filament spools while they are loaded and ready to print. This combines the workflow, saves considerable time, and dramatically improves print reliability, especially with moisture-sensitive materials like PETG and TPU. It effectively brings a professional-level feature, previously reserved for industrial machines or dedicated extra equipment, into an entry-level combo package.

This innovation also presents its own trade-offs. As a newer system in 2025, it has a shorter real-world track record compared to the long-established AMS Lite. Early adopters may encounter a steeper learning curve or software quirks that have long been worked out in the Bambu ecosystem. The long-term reliability of its internal filament swapping mechanism, while promising in design, is still building the extensive user data history that its competitor enjoys.

Core Printer Performance

Out-of-the-Box Experience

When it comes to getting started, both companies have made significant improvements for beginners. The Bambu Lab A1 is known for a setup process that is as close to plug-and-play as possible. Assembly is minimal and guided by clear instructions.

The A1's real strength is its fully automated, hands-off calibration routine. Upon startup, it performs a series of checks that include not just automatic bed leveling, but also setting the Z-offset, running vibration compensation for both X and Y axes, and even calibrating nozzle pressure advance. This comprehensive automation virtually guarantees a perfect first layer with no manual adjusting, a massive benefit for new users.

The Anycubic Kobra 3 features its LeviQ 3.0 auto-leveling system. This is an advanced multi-point leveling process that maps the bed surface to ensure proper nozzle height across the build plate. While highly effective, the process is not as completely automated as the A1's. Users may still need to perform a manual Z-offset adjustment to dial in that perfect "squish" for the first layer.

Regarding the user interface, both printers feature a color touchscreen. The A1's UI is deeply connected with its cloud services and the AMS Lite, providing a very streamlined, guided experience. The Kobra 3's interface is functional and clear, offering direct control over the printer's core functions and the ACE Pro system. The choice between them often comes down to a preference for Bambu's guided, app-like feel versus Anycubic's more traditional, direct-control layout.

Speed, Quality, and Mechanics

It is crucial to look beyond the maximum advertised speeds, which often exceed practical use cases. Both printers are capable of very high speeds, but for high-quality results, real-world performance is what matters. In typical printing scenarios with standard materials, both the A1 and Kobra 3 can produce excellent quality prints at speeds that would have been unthinkable for consumer printers just a few years ago. The key differences lie in their core mechanics.

When comparing single-color print quality using a standard material like PLA, both machines are top-performers. Tests for dimensional accuracy, surface finish, and overhang performance show them to be highly competitive. Minor differences can often be attributed to slicer tuning rather than fundamental hardware limitations.

The A1 uses metal linear rails on its X and Z axes. This is a premium feature for a bedslinger design, providing exceptional rigidity and smooth motion. This contributes to reduced ringing and artifacts, allowing the A1 to maintain high print quality even at aggressive acceleration settings. The Kobra 3, in contrast, uses a more traditional motion system.

Both printers feature all-metal hotends capable of reaching temperatures suitable for a wide range of materials, and both have implemented quick-swap nozzle designs. This makes maintenance and changing nozzle sizes a simple, tool-free process, lowering the barrier to experimentation and repair.

In terms of build volume, the two are nearly identical. The A1 offers a 256x256x256 mm volume, while the Kobra 3 provides a 250x250x260 mm space. This minor difference is negligible for most projects. Both typically ship with a textured PEI build plate, which provides excellent adhesion and a desirable matte finish on the bottom of prints.

Reliability and Maintenance

By 2025, both models have established a public record of reliability. The A1, despite its strong performance, had a well-documented product recall related to its heatbed cable early in its lifecycle. Bambu Lab handled this with a comprehensive replacement program, and later versions of the hardware have resolved the issue. This history, however, remains a data point for potential buyers.

The Kobra 3, being a newer platform, has its own set of community-reported issues. Early software versions may have bugs that are addressed over time through updates. Users on forums and Reddit discuss the learning curve associated with the new ACE Pro system and dialing in its performance. It's crucial for prospective buyers to research the current state of software maturity and community feedback.

Maintenance on both machines is straightforward. The quick-swap nozzle assemblies make clearing clogs or changing sizes trivial. Cleaning the linear rails on the A1 or the motion systems on the Kobra 3 are routine tasks familiar to anyone in the hobby. The accessibility of parts and the design for maintenance are strong on both models.

The Ecosystem

Slicer Software

The slicer is the critical link between your digital model and the printer. Bambu Studio has earned a reputation as the "Apple" of 3D printing software. It's known for an exceptionally user-friendly interface that is powerful underneath. Features like built-in multi-color painting, support for mesh modifiers, and seamless cloud integration make the entire workflow feel unified and polished. It is highly optimized for the A1 and AMS Lite, making the process intuitive.

Anycubic Slicer is built upon the foundation of the highly-respected open-source PrusaSlicer. It is a capable and powerful tool, but the level of integration with the Kobra 3 and the ACE Pro system is a key consideration. While functional, the workflow for setting up and managing multi-color prints may not feel as seamlessly integrated as its Bambu counterpart.

Fortunately, the community has stepped in. Both machines can be used with powerful third-party slicers like OrcaSlicer. This allows advanced users to escape the confines of the manufacturer's software and fine-tune every aspect of the printing process, including multi-material profiles.

Community and Support

The ecosystem extends beyond the hardware and software to the people who use it. Bambu Lab has built a massive, highly active global community. Official forums, Reddit sub-communities, and Facebook groups are bustling with activity, providing a vast knowledge base for troubleshooting, modifications, and print showcases.

Anycubic also has a large and long-standing community, but the user base for the new Kobra 3 Combo is still growing relative to the A1's established presence.

When it comes to official support, user experiences with both companies can vary. It is advisable to research current customer service response times and effectiveness in your region. Both companies provide extensive online documentation through their official Wiki or Help Center platforms. These are invaluable resources for step-by-step guides, troubleshooting, and understanding the deeper functions of the machines. The maturity of the A1 means its knowledge base is arguably more comprehensive, with solutions for a wider range of specific issues.
