Bambu A1 vs P1S – Check Which One Is Best & Why?

Why Do I Recommend The Bambu P1S?

• The Bambu P1S features a fully enclosed chamber for stable internal temperatures and improved performance with high-temperature filaments like ABS and ASA, while the Bambu A1 uses an open-frame design.
• Bambu P1S comes with a CoreXY motion system for faster, more precise movement and reduced vibration artifacts, whereas the Bambu A1 uses a bedslinger Y-axis motion design.
• It includes an activated-carbon air filtration system to reduce odors and particulate emissions when printing enclosed, while the Bambu A1 lacks integrated filtration and exposes prints directly to the surrounding air.
• The Bambu P1S supports the full AMS multi-material system for expanded color and material flexibility, whereas the Bambu A1 supports only the AMS Lite version with fewer spool connections.
• Bambu P1S features a chamber camera for clear time-lapse recordings inside the print area, while the Bambu A1 uses a toolhead-mounted camera that captures a less consistent viewing angle during prints.
• It includes a more powerful auxiliary part-cooling fan for enhanced layer bonding and improved overhang performance, whereas the Bambu A1 relies on a single standard part-cooling fan.
• The Bambu P1S supports higher heat-bed temperatures up to 110 °C to ensure reliable adhesion for advanced polymers, while the Bambu A1 is limited to lower bed temperatures.
• Bambu P1S has a sturdier, fully enclosed chassis for reduced noise and better dust protection during long prints, whereas the Bambu A1 has an open structure that generates more operational noise and exposes components to external conditions.

Maybe the Bambu A1 can make you comfortable because it’s a little bit cheaper than the Bambu P1S. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

What Common Both Can Do?

• Build Volume: Both printers share the same 256 × 256 × 256 mm build area, giving users identical working space for medium-sized models and multi-part projects without resizing between machines.
• Layer Resolution: Each supports a 0.1 – 0.4 mm layer range, ensuring comparable print smoothness and quality for fine details or faster prototyping depending on user preference.
• Max Print Speed: Both reach up to 500 mm/s, allowing extremely fast printing compared to most consumer printers, ideal for reducing turnaround time without significant loss of detail.
• Max Acceleration: Each can reach 20 m/s² acceleration, enabling high-speed moves and reduced print times on large or complex jobs with efficient motion control.
• Filament Diameter: Both use 1.75 mm filaments, the most common standard, ensuring compatibility with a wide variety of filament brands and materials.
• Nozzle Diameter: Each uses a standard 0.4 mm nozzle, delivering a balanced mix of detail and throughput suitable for everyday printing tasks.
• Auto Bed Leveling: Both include automatic bed leveling sensors, simplifying setup and maintaining first-layer consistency without manual calibration.
• Input Shaping: Each printer uses input shaping technology to counter vibrations, improving accuracy and reducing ringing on high-speed prints.
• Flow Calibration: Both models feature automatic flow calibration, optimizing extrusion rates for better dimensional accuracy and consistent surface finishes.
• Wi-Fi Connectivity: Both connect via Wi-Fi, allowing remote print monitoring, control, and firmware updates directly through Bambu Studio or mobile apps.
• Camera Monitoring: Each includes a built-in camera, enabling live viewing, time-lapse recording, and remote supervision of prints.
• Power Loss Recovery: Both can resume printing after power interruptions, protecting long prints from being lost due to unexpected outages.
• Filament Run-Out Sensor: Each machine detects filament depletion, automatically pausing and prompting for a refill to prevent incomplete prints.
• Multi-Color Printing Support: Both can print in multiple colors when used with the AMS system, providing creative flexibility for decorative and functional prints.
• AMS Compatibility: Both are compatible with the Bambu AMS ecosystem, enabling automatic filament switching and extended multi-material workflows.
• Touchscreen Interface: Each uses a touchscreen for control, offering intuitive navigation and easy access to settings and print management.
• Direct Drive Extruder: Both use a direct drive feeding mechanism, improving performance with flexible filaments and maintaining consistent extrusion.
• Heated Bed: Each has a heated build plate, improving first-layer adhesion and minimizing warping on standard and advanced filament types.
