Bambu Lab P2S
About the Bambu Lab P2S
The Bambu Lab P2S is a 2025 update of their 2023 P1S. It brings the P series up to the specifications of the Bambu Lab H2S. Its print volume is 256 X 256 X 256 mm and it’s fully enclosed with CoreXY kinematics, printing at 600mm/s peak with 20,000 mm/s² acceleration. It replaces the P1S’ outdated monochrome VFD dot matrix click wheel screen with a 5” full color touchscreen like the H2S. The extruder is now identical to the H2S, with dual hardened steel gears feeding a high flow (40mm³/s) quick swap nozzle, magnetically mounted and retained with a bracket and latch very similar to the Bambu Lab A series. The extruder motor is the PMSM servo motor used in the H2S, which exerts 8.5kg of force (70% more than the P1S) and samples resistance and position at 20 kHz to immediately detect clogs and filament grinding. The maximum temperature of the nozzle is 300°C and the textured PEI magnetically-attached removable steel plate print bed can reach 110°C. The enclosure is temperature controlled, blowing in cooling air for low temperature filaments, and venting air using a variable-position damper through an activated carbon filter for hazardous filaments like ABS and ASA. This arrangement can maintain the chamber air at up to 50°C, but doesn’t use active heating. The printer interfaces to the network using dual-band WiFi. The P2S combo comes with the AMS 2 Pro, a 4-filament feeder system with filament drying capabilities, as well as the single filament high temperature AMS HT and the older AMS. It is compatible with up to 4 AMS 2 Pros and 4 AMS HTs for a total of 20 filaments.
Benefits of the Bambu Lab P2S
Modern mainboard features - Many 3D printer features relate to the version of the mainboard and firmware, including features like resuming prints after a power failure and support for silent stepper motor drivers for quieter printing. Newer boards also include safety features like thermal runaway protection which shuts the printer down if it detects issues with overheating.
Auto bed leveling - auto bed leveling will ensure your prints have perfect first layers every time and greatly reduce issues with bed adhesion. When using an auto-leveling system, the probe allows better tolerances for slightly warped print beds by measuring and compensating for any inconsistencies. Without this feature, you'll need to adjust the bed level manually using nuts on each corner of the print bed.
Has touch screen - having a touch screen isn't a deal-maker or breaker, but it is a convenient feature that makes it easier to navigate the interface when you are printing files and configuring 3D printing settings.
Fully assembled - This 3D printer is shipped completely assembled, and is ready to plug in and start using as soon as you unbox it. You will still need to follow the included calibration procedures, but this will not take a significant amount of time.
Direct drive extruder - Direct drive extruders are mounted right above the hot end, and push the filament directly into it, as opposed to a side mounted bowden extruder setup. We prefer direct drive extruders to bowden since they are less prone to jamming and typically require less maintenance. they also are much easier to use with flexible materials
PEI build surface has good balance of adhesion and part removal - PEI beds are one of the more premium build surface options, and for good reason. They offer great first layer adhesion with no spraysor other treatments, and can be flexed to quickly remove parts. You'll need to clean the bed with a solvent like acetone or IPA every so often to maintain the bed's adhesion.
Wireless printing - In addition to the standard USB and SD card connections, you can connect wirelessly to this printer to print from your computer or mobile device.
Linear rail motion system - Linear rails provide added stability to the moving parts of the printer, allowing higher printing speeds without sacrificing quality. Keep in mind that the most important factor to consider when optimizing for print speed is the flow rate of filament, which depends on the hot end and nozzle size moreso than the motion system.
CoreXY Kinematic System - A CoreXY 3D printer kinematic system uses two stationary motors to move the print head in the X and Y directions, resulting in faster and more precise movements compared to traditional printers. By separating the movement of the print head from the movement of the build plate, the CoreXY system is able to avoid the added weight and momentum of a moving build plate. This results in less vibration and better control of the print head, allowing for faster and more precise movements. Additionally, the CoreXY system can print at higher speeds compared to H-bot systems because it only needs to move one motor for each axis of movement, reducing the overall weight and inertia of the system.
All-metal hot end - An all-metal hot end allows for printing at high temperatures up to 300C, while standard hot ends are capped at 260C before the PTFE material begins to degrade. All-metal hot ends are also less susceptible to jamming, and do not degrade as fast.
Enclosure - An enclosure seals air around the print area. This holds warm, still air around the print area and is essential for printing temperature-sensitive materials like ABS. Enclosures also prevent particulates and gasses from being emitted into the surrounding area, increasing safety. They also greatly reduce printer noise.
Dual gear extruder - A dual gear extruder grips filament from both sides and can exert much more force on the filament before slipping. It helps with all filaments but especially with flexible, slippery TPU.
Where to buy the Bambu Lab P2S
Brand Summary: Bambu Lab
Bambu Lab, founded by ex-DJI engineers in Shenzhen, has made waves in the 3D printing industry with its focus on speed, innovation, and user-friendliness. While it began its journey through a successful Kickstarter campaign, raising $7 million in a month, the brand has since had its share of growing pains, including shipping issues and firmware bugs. The company's commitment to creating intuitive, precalibrated 3D printers like the X1-Carbon and P1P is commendable, but some users have found limitations with the proprietary components and software. Despite these challenges, Bambu Lab boasts a large community of dedicated users across various platforms and continues to evolve in its offerings and customer service.
