First, the Praise: Why the Bambu Lab P2S Wows in Our Review

Our Bambu Lab P2S review confirms it—this printer is built for users who want their voices heard. The Bambu Lab P2S team addressed nearly every complaint from the P1 series, delivering upgrades that matter:

  • User Experience Refresh: The Bambu Lab P2S swaps the outdated black-and-white screen for a smooth 5-inch touchscreen (854×480 resolution) that feels responsive and intuitive—no more squinting at tiny buttons. Storage shifts from a fragile TF card which we suggest many time switch to the SLC/MLC card from my previous BLOG. Now they decide to change to the USB drive, a small but impactful change we highlighted in our Bambu Lab P2S review.

  • Hardware Polish: The Bambu Lab P2S adds a side handle for easy carrying, replaces messy carbon rods with low-maintenance hollow optical axes, and upgrades the print bed base to metal (say goodbye to plastic breakage). Our Bambu Lab P2S review also notes the build plate redesign—cleaning is now a breeze, and the heated bed reaches 80°C in just 48 seconds.

  • Performance Gains: The Bambu Lab P2S maintains a 256×256×256mm print volume but eliminates the lower-left dead zone, enabling full-size prints. The monitoring camera jumps from a laggy "0.5fps slideshow" to 1080p 30fps HD, and the redesigned waste chute survived 3,000 color changes in our Bambu Lab P2S review—color printing has never been more stable.

  • Quiet Operation: A major win in our Bambu Lab P2S review is the reduced exhaust fan noise. The Bambu Lab P2S runs quietly enough for bedroom or office use, making it ideal for US users who print at night without disturbing others.

Bambu Lab P2S Review: The Two Critical Pain Points

No printer is perfect, and our Bambu Lab P2S review uncovered flaws that US users can’t ignore—both tied to compromised thermal and ventilation design:

Pain Point 1: Heat Buildup Causes Clogging (A Top Bambu Lab P2S Gripe)

Our Bambu Lab P2S review found that the printer’s shared fan system (auxiliary + chamber temperature) is a major downside. The Bambu Lab P2S lacks an independent cooling module, relying on a valve to switch modes—this leads to:

The Shared fan system
  • Severe heat buildup on the Bambu Lab P2S top when ambient temps exceed 33°C (92°F), triggering heat creep in PETG/ASA filaments. Our Bambu Lab P2S review recorded frequent nozzle clogs during high-flow printing, a dealbreaker for efficiency-focused users.
  • Bambu Lab’s workaround—printing with the door open or adding a riser—undermines the P2S’s silent design and lets heat warp prints. The Bambu Lab P2S also struggles with moisture absorption in filament paths, worsening jams for US users in humid climates.

Pain Point 2: Ventilation Flaws Risk Health (A Key Bambu Lab P2S Concern)

Ventilation is a critical oversight in the Bambu Lab P2S, as our review emphasizes. The Bambu Lab P2S removes the independent exhaust fan, relying on a leaky internal circulation system:

  • The Bambu Lab P2S’s movable valve can’t seal 100%, allowing unfiltered air to seep in. Our Bambu Lab P2S review detected plastic odors and micro-particles escaping during printing—harmful for long-term use in closed US homes or studios.
  • Cooling mode on the Bambu Lab P2S blows unfiltered external air directly into the room, while opening the door for heat dissipation spreads fumes. US users are left choosing between safe air and print quality—a dilemma our Bambu Lab P2S review aims to solve.

Bambu Lab P2S Review: Must-Have Upgrades to Fix Its Flaws

Considering the pain point. Call3D now proves the printer shines with two key accessories: Call3D CoolDry Pro (for heat buildup) and FNATR Ventilation System (for air quality). Together, they turn the Bambu Lab P2S into a US-friendly workhorse.

Upgrade 1: CoolDry Pro – Solve Bambu Lab P2S Heat Buildup

Our Bambu Lab P2S review confirms this is non-negotiable for US users:

  1. Active Cooling for Bambu Lab P2S: Delivers 10-17°C dry air to the Bambu Lab P2S heatsink, stabilizing extruder temps at 22.4°C—even in 34°C+ rooms. No more heat creep or clogs in the Bambu Lab P2S.
  2. Boost Bambu Lab P2S Performance: The Bambu Lab P2S can now print PETG at 280°C for glossier results, or run high-flow HF PETG—perfect for US print farms or hobbyists chasing speed.
  3. Moisture Protection for Bambu Lab P2S: Creates a dry filament path, critical for US users in humid regions. The Bambu Lab P2S avoids swollen TPU/PETG and feeder gear corrosion.
  4. Plug-and-Play for Bambu Lab P2S: Installs in 10 minutes, no mods needed. Runs at 48dB—quieter than the Bambu Lab P2S itself.

Upgrade 2: FNATR Ventilation System – Fix Bambu Lab P2S Ventilation

Our Bambu Lab P2S review rates this as essential for US health-conscious users:


  1. Rapid Airflow for Bambu Lab P2S: 6000 RPM fan refreshes the Bambu Lab P2S enclosure air in 60 seconds, expelling top 积热 without opening the door.
  2. 5-Stage Filtration for Bambu Lab P2S: Captures 99.97% of 0.3-micron particles, blocks 98% of total particles, and neutralizes VOCs. Our Bambu Lab P2S review found zero odors during closed-door printing.
  3. 3 Modes for Bambu Lab P2S: Silent (30dB) for home use, Balanced for long prints, Performance for ABS—perfect for US users’ varied needs.
  4. Easy Install for Bambu Lab P2S: Pre-attached hoses and hardware fit the Bambu Lab P2S seamlessly, no complex modifications.

Bambu Lab P2S Review: Why the Upgrade Combo Works for US Users

In our Bambu Lab P2S review, pairing CoolDry Pro and FNATR Ventilation System delivers 1+1＞2 results for the Bambu Lab P2S:

  • The Bambu Lab P2S stays cool internally (CoolDry Pro) and exhausts clean air externally (FNATR)—no more clogs, odors, or compromised silence.
  • US print farms benefit from higher throughput and less material waste, while home users get a safe, quiet Bambu Lab P2S experience.

Conclusion of our Bambu Lab P2S review : Final Verdict for US Users

Our Bambu Lab P2S review concludes that the printer is absolutely worth buying—with the right upgrades. The Bambu Lab P2S’s user-driven design, print quality, and quiet operation make it a top pick, but heat buildup and ventilation flaws hold it back. For US users, Call3D CoolDry Pro and FNATR Ventilation System aren’t just nice-to-haves—they’re must-haves that fix the Bambu Lab P2S’s biggest issues. Whether you’re a hobbyist printing in your garage or a professional running a small farm, this Bambu Lab P2S review proves the printer, paired with these upgrades, delivers the reliability, safety, and performance US 3D printing enthusiasts demand.
