Break Through the Limits of 3D Printing: The Ultimate Guide to Upgrading to the Bambu Lab P2S Combo

The Practicality and Joy of 3D Printing: Fulfilling the 'If It Doesn't Exist, Make It' Spirit

The greatest appeal of a 3D printer lies in its ability to materialize what you want with the spirit of 'if it doesn't exist, make it,' without relying on the commercial market. I have personally designed and printed numerous practical parts and hobby items using Autodesk Fusion.

For example, when setting up my Gran Turismo 7 gaming environment, I custom-built a dedicated stay to rigidly mount a 15-inch portable monitor directly above the steering controller. A bracket satisfying such a niche demand would never be available in stores. It is truly the unrivaled domain of personal design. Even for a custom shelf installed above the TV, I eliminated the clunky adjustment mechanisms of generic products and built a sturdy, low-cost alternative that fits my home TV down to the millimeter.

Beyond practical items, I have also created aesthetically driven pieces, such as an organically designed business card holder modeled after a jellyfish. With careful sanding and painting, even a single material can exude the striking presence of a crafted artifact. However, in my previous setup, the hassle of changing filaments and the strict storage requirements forced me to operate under the severe constraint of 'only being able to use one type of material and color at a time.'

Deep Frustrations and Physical Limits with the Current Machine (Adventurer 3)

Although I have heavily used the FlashForge Adventurer 3 for years, every time I tried to print more advanced designs, I faced desperate stress caused by its outdated hardware. The biggest bottleneck was the trade-off between 'filament capacity and enclosure sealing.' Since the relatively expensive standard 500g spools would run out during large prints, I removed the side cover to use a 1kg spool externally. The cost of this was that the internal heat leaked out completely, making it virtually impossible to print ABS resin, which requires strict temperature control.

What made it even more agonizing was the endless series of print failures caused by the manual 9-point leveling and the Bowden extrusion system. Even a micron-sized speck of leftover resin on the nozzle tip would throw off the measurements, causing the first layer adhesion to fail miserably. Due to the long distance from the motor to the nozzle, even pushing retraction to its limits couldn't fully relieve the pressure, resulting in severe stringing and ugly blobs.

The final straw was a major accident where the fast-moving nozzle crashed into accumulated blobs, knocking off the simply-secured build platform entirely. The sense of emptiness when a complex part that took hours to print collapses with a loud 'Crash!' and turns into garbage is indescribable. Trying to cover up the machine's flaws through clever design work had finally reached its limit.

Transitioning to a Next-Generation Machine: Comparing the Enclosed High-Speed P2S and 5M Pro

To stably print ABS and ASA, which are essential for motorcycle parts and the like, I narrowed down my next machine to the latest 'fully enclosed' high-speed models. The final candidates were FlashForge's orthodox evolution, the 'Adventurer 5M Pro,' and Bambu Lab's latest flagship, the 'P2S (Standalone).' Both machines use a direct drive system, making them evenly matched in their ability to eradicate the dreaded stringing problem.

Comparison ItemFlashForge Adventurer 5M ProBambu Lab P2S (Standalone)
Estimated PriceAround 80,000 - 85,000 JPY109,000 JPY

Sensor Calibration25-point nozzle contact levelingEddy Current (High-density distortion mapping)
Multi-Plate ManagementNot supported (Individual transfer)Supported (Infinite management in 1 file)
AI Error MonitoringNone (Remote camera only)NPU equipped, Spaghetti/Blob detection


Looking only at the price, the 5M Pro might seem like the winner. However, the Bambu Lab P2S possesses an 'ideological superiority in software' and 'fully automatic calibration capabilities' that easily overturn the price difference. In particular, Bambu Studio's 'Multi-Plate Management' is outstanding. It allows you to manage multiple parts, such as a controller case and top plate, in a single 3MF file, preventing data scattering and offering overwhelming convenience when sharing on platforms like MakerWorld. Furthermore, the fully automatic micro-scanning of thermal distortion using the eddy current sensor makes the very concept of leveling a relic of the past. True automation, where you can 'just press a button and walk away' without worrying about any numbers, is exactly what I was looking for.

Why the 'Combo'? The Complete Liberation of Design Freedom Brought by Multi-Material Support

The biggest deciding factor in choosing the 'Combo' equipped with the AMS 2 Pro for an additional investment of about 40,000 JPY, rather than the standalone P2S, is nothing other than the liberation of design freedom through 'PLA × PETG' multi-material support. In previous single-material prints, the support material would strongly fuse with the main body, making the process of tearing it off with pliers an absolute hell. Moreover, the bottom surface after removal was left in a miserably rough state. As a result, I had developed a habit of compromising during the design phase to avoid hollow structures and steep overhangs.

However, with the AMS 2 Pro, you can fully utilize the cheat-level characteristic that 'PLA and PETG will absolutely never chemically bond.' While printing the main body and support pillars in PLA, it automatically switches to PETG only for the 'last few layers (interface surface)' that touch the model. Through this magical operation, you can set the gap with the support to '0.0mm (perfect contact)' in the slicer, resulting in even the bottom of mid-air structures finishing as smooth as glass.

After printing is complete, no tools are required whatsoever. It peels off cleanly and instantly with just your fingertips. Bizarrely complex designs that I previously gave up on, thinking 'shapes requiring supports are a no-go,' can now be 100% materialized exactly as I envisioned them in Fusion 360. I can confidently say that this innovative feature alone makes the Combo model more than worth the extra 40,000 JPY.

Automatic Drying While Loaded: Ultimate Filament Management and Economy

Another compelling reason to choose the Combo is the complete elimination of 'daily hassles' in filament management. Engineering plastics like PETG and ABS are highly prone to absorbing moisture, which previously forced me into the fruitless task of taking them in and out of a giant dry box every time I printed. However, the included 'AMS 2 Pro' features an internal 65°C active hot air drying function. You can keep up to four spools loaded and always on standby in an optimal, ultra-dry state. That wasted time of constantly opening and closing cases will completely disappear from your daily routine.

Furthermore, Bambu Lab's official filaments boast incredible competitiveness in terms of running costs. From the second spool onwards, you can cheaply purchase spool-less 'refills,' which take just 5 seconds to load by simply snapping them onto an empty spool. By fully utilizing the official store's bulk purchase discounts (30% off for 4 or more, 40% off for 10 or more), you can procure high-quality official materials much cheaper than buying third-party products of questionable quality.

Thorough Comparison with Major Competitors and Final Conclusion

Finally, to get a bird's-eye view of where the P2S Combo stands, I compared it with currently hot, multi-material capable enclosed competitors. I will delve into the 'reality of actual operation' that cannot be seen from the numbers on a spec sheet alone.

Material UnitAMS 2 Pro (4 colors)CANVAS (4 colors)CFS (4 colors)QIDI Box (External)
Filament Drying65°C Active Circulating Hot AirNot supportedPassive Drying (Sealed)Relies on separate external dryer


Elegoo's Centauri Carbon 2 Combo catches the eye with its price-destroying cheapness of about 80,000 JPY, but its material unit lacks an active drying function. In an operation where moisture-sensitive engineering plastics are kept constantly on standby, relying on silica gel for passive drying is far from reassuring. On the other hand, large machines from Creality and QIDI boast intense specs like built-in chamber heaters, but they are clearly overkill for home use. Their massive installation footprint and high initial costs become bottlenecks.

Judging comprehensively, considering the overwhelming reliability of the hardware, the stress-free environment of material management through active drying, and the sophistication of the software ecosystem centered around Bambu Studio, I am convinced that investing in the Bambu Lab P2S Combo is currently the most rational choice and the optimal solution to drastically change my future creative life. If you seek uncompromising craftsmanship, this is the machine you should choose without hesitation.

The Best Investment for Uncompromising Craftsmanship

Keeping the joy of design cultivated with the Adventurer 3, it makes all the frustrations caused by the machine's physical limits a thing of the past. That is the Bambu Lab P2S Combo. The liberation of design through multi-material support, fully automatic calibration, and ultimate filament management via active drying. These are not mere improvements in catalog specs, but a dramatic paradigm shift that elevates a personal desk to a 'factory level.' As soon as the actual machine arrives, I plan to thoroughly review the ease of setup and actual print quality from an uncompromising perspective.
