Choosing the right 3D printer can make or break your projects — whether it’s speed, reliability, or material capability you care about. The Bambu A1 is a solid, budget-friendly machine with core 3D printing essentials, while the Bambu Lab P1S advances into faster motion, broader filament support, and an enclosed design. Here’s a true side-by-side — and why *P1S is our top pick.
If you want faster prints, stronger reliability, and wider material flexibility right out of the box, then the Bambu Lab P1S is the better all-around 3D printer. The A1 is great for basic builds and easy multi-color prints, but **P1S pushes ahead with a more advanced motion system, a fully enclosed frame for better temperature stability, and broader filament support — especially for tougher materials — making it ideal for both hobbyists and prosumers.
Why Do I Recommend Bambu Lab P1S?
- Faster, more capable mechanics: P1S uses a CoreXY motion system with higher acceleration (~20 m/s²) compared to the A1 (10 m/s²), helping it handle rapid movements and complex prints more efficiently without sacrificing quality.
- Enclosed print chamber: The P1S has a fully encloed frame, which improves thermal consistency and makes printing temperature-sensitive materials like ABS and ASA more reliable.
- Broader materials support: With the enclosed design and robust motion system, P1S handles a wider range of filaments (including some engineering plastics) better than the A1, which is more focused on standard filaments like PLA and PETG.
- Multi-color capable via AMS: Like A1, P1S supports multi-material/multi-color printing via Bambu Lab’s AMS system, but its enclosed build and motion design help turn out more consistent multi-filament prints.
- Great value if you plan to grow: For users who want a machine that scales with skill and project complexity, P1S gives you more headroom without jumping to a much more expensive model.
Detailed Comparison & Recommendation
| Feature | Bambu A1 | Bambu Lab P1S | Which & Why |
|---|---|---|---|
| Motion System | Cartesian bedslinger | CoreXY high-speed | P1S — faster motion handling |
| Max Acceleration | 10 m/s² | 20 m/s² | P1S — smoother rapid moves |
| Build Chamber | Open frame | Fully enclosed | P1S — better thermal control |
| Material Support | PLA/PETG focus | Broader materials including ABS/ASA | P1S — better advanced materials |
| Multi-Color Printing | AMS Lite compatible | AMS compatible | Tie — both support multi-filament |
| Ease of Use | Very beginner-friendly | Great for all levels | Tie — both good, P1S more advanced workflow |

What Are the Major Differences
- Speed & Performance
- The P1S’s CoreXY system is inherently faster and more rigid than the A1’s bedslinger design, giving it better movement precision and the ability to maintain quality at higher speeds.
- Thermal Stability & Materials
- Because P1S is fully enclosed, it maintains more consistent internal temperatures. This makes printing temperature-sensitive filaments like ABS and ASA less prone to warping — whereas the A1 is best optimized for PLA, PETG, and TPU-like filaments.
- Build & Mechanics
- A1’s design is simpler and often more beginner-oriented, while P1S’s enclosed frame and CoreXY mechanics show their strength when tackling more intricate or longer prints that benefit from thermal stability and dynamic motion.
- Expandability & Long-Term Use
- Both support AMS for multi-color printing, but P1S’s capability with multiple AMS units and enclosed chamber gives it a slightly more future-ready platform for advanced projects.

Fair Advice to Consider
- Go with Bambu A1 if you’re just starting out and mostly print PLA/PETG/TPE — it’s reliable, simple, and gets great results with minimal tuning.
- Choose Bambu Lab P1S if you want higher motion performance, more advanced materials support, and stability from the enclosed frame — especially if you plan to print longer jobs, larger parts, or tougher filaments.
- Both models share multi-color printing support via Bambu’s AMS, but P1S’s design helps keep prints more consistent and less prone to environmental variation.
Quick Comparison
| Category | Winner | Why |
|---|---|---|
| Speed & Motion | P1S | CoreXY with higher acceleration |
| Material Handling | P1S | Better with ABS/ASA etc. |
| Beginners & Simple Prints | A1 | Simpler setup and workflow |
| Multi-Color Support | Tie | Both support AMS |
| Value for Future Projects | P1S | Broader materials & stronger build system |
Quick Summary
The Bambu A1 is a very capable 3D printer for standard filaments and day-to-day projects, perfect for beginners and straightforward prints. However, the Bambu Lab P1S ups the game with a CoreXY motion system, enclosed frame, better thermal control, faster acceleration, and broader material support — making it a more versatile and future-ready choice for most makers and advanced hobbyists who want a machine that grows with their skill.
