The Bambu Lab P1S is a compact desktop FDM 3D printer which boasts a number of unique features that set it apart from most devices in its class. As a part of the P1 series, the machine is based on the design of the company’s flagship X1 series and offers the same incredible print speed of 500 mm/s without sacrificing print quality. Being an upgraded version of the previous P1P model, it features a fully enclosed body which improves print performance for advanced filaments as well as enhanced cooling and filtration capabilities. The latter include an auxiliary cooling fan for objects printed, a chamber regulator fan to stabilize the inner chamber temperature, and a control board fan to assist in cooling the control board. Furthermore, the device comes with speed feedback sensor monitors ensuring optimal fan speed and a built-in activated carbon filter for a more comfortable printing process. The P1P 3D printer can be upgraded to the P1S version with the special upgrade kit, which is more cost-effective than buying individual spare parts.
To achieve impressive printing results, the Bambu Lab P1S model features CoreXY kinematics with linear rods on Z and Y axes and carbon rods on the X-axis for smooth movements. This allows for up to 20000 mm/s² acceleration while the active vibration compensation algorithm and pressure advance add to stability and make for consistent high-quality prints even at the lightning-fast speeds.
As for quality-of-life features, the Bambu Lab P1S is equipped with an automatic multipoint sensor-based bed leveling mechanism, filament runout sensor, power loss recovery, remote monitoring and timelapse functions as well as the ability to add various upgrades, including the company’s system for multi-material printing (AMS), allowing it to combine 4 filaments in one project (and up to 16 filaments using four multi-material systems and the AMS hub). Overall, with a set-up of just 15 minutes, the machine works right out of the box and provides a smooth trouble-free 3D printing experience.

The Bambu Lab P1S 3D printer is equipped with a direct-drive extruder that ensures smooth and precise filament feeding and facilitates flexible materials handling. Due to its sturdy design, semi-automatic belt tensioning, and cutting-edge control algorithm with the help of vibration compensation and pressure advance, the P1S reliably prints dimensionally accurate parts of outstanding quality even at top speeds.
The automatic bed leveling sensor calibrates and levels the bed properly, providing a perfect first layer for every project. Also, thanks to the flexible PEI-coated build plate, the printer guarantees better adhesion and easy removal of finished prints.
The all-metal hotend is equipped with a stainless steel 0.4 mm nozzle and can heat up to 300 °C, providing compatibility with a wide range of thermoplastics, including PLA, PETG, TPU, PVA, PET, ABS, ASA, PA, PC, and flexibles. The hotend features an all-in-one design that speeds up heating and simplifies maintenance, but the nozzles are not interchangeable. That means you will have to replace the hotend as a whole in case you need another nozzle diameter. The manufacturer does not recommend printing abrasive materials, like fiber-reinforced composites, with a default nozzle, but you can purchase an optional hotend with a hardened steel nozzle with no limitations on filaments being used.
The Bambu Lab P1S is an open-material system that can print with proprietary and third-party filaments alike.
To reduce plastic waste, the manufacturer suggests utilizing reusable spools for their filaments. One can reuse the previous spool, print their own spool (the file comes with the printer), or purchase one.
The build volume of 256 x 256 x 256 mm is spacious enough for a desktop 3D printer and is suitable for small to medium objects printed as a whole. Larger models can be printed in parts and then assembled.
The Bambu Lab P1S is controlled via a 2.7" LCD screen with a control dial instead of a more conventional touchscreen. The modest display characteristics are compensated with the capability of remotely operating the machine via the Bambu Handy mobile app. The built-in chamber camera enables easy print monitoring and timelapse video creation.
To prepare 3D models for printing, the manufacturer recommends using the proprietary Bambu Studio slicer which runs on Windows and macOS. Bambu Studio is capable and easy-to-use software that greatly adds to the convenience of working with the printer. The software provides a project-based workflow, supporting 3MF format, which offers many useful features, such as multi-plate support, a project resource manager, and assembly / part view. It also allows for remote print monitoring and management of multiple devices.
The machine features Wi-Fi, Bluetooth, and Bambu Bus connectivity, the files can also be transferred to the printer via a microSD card.
The Bambu Lab P1S Combo add-on includes:
For some items, package content may change. In case of any questions, please get in touch.
P1P to P1S upgrade kit
The Bambu Lab P1P to P1S Upgrade Kit (can be purchased from the P1P page) contains all you need to upgrade your P1P 3D printer to the P1S version (excluding the Bambu Textured PEI Plate, which is purchased separately). The kit includes:
Bambu Lab AMS (Automatic Material System)
The Bambu Lab AMS is an airtight box that houses four filament slots and is equipped with humidity sensors, keeping the filaments dry and ready to use. The system allows combining multiple materials in one project. The manufacturer does not recommend using flexibles and fiber composites with the AMS, except for Bambu PA-CF and PAHT-CF which have been specifically designed to be compatible with the system. Each AMS comes with four reusable filament spools.
Stainless steel extruder unit — P1 series
The stainless steel extruder unit is equipped with double gears made from stainless steel, which provides increased extrusion force and prevents slippage. The extruder is suitable for most commonly used filaments and equipped with a special sensor that supports filament break detection to prevent print failures.
Hotend with nozzle
The Bambu Lab hotend features a unique all-in-one design that combines the heatsink, throat, heater block, and nozzle into a single unit. The nozzle selection guide below will help you choose the appropriate nozzle according to your printing tasks and materials being used.
Bambu textured PEI plate
The Bambu textured PEI plate provides strong adhesion, perfect first layer, and effortless print removal alongside improved durability and compatibility with various filaments.
Ceramic heater & thermistor — P1 series (3 pcs)
The ceramic heater and thermistor for the Bambu Lab P1S 3D printer are combined into one module with an integrated terminal connector. The thermistor provides highly accurate temperature measurement. The range of operating temperatures is –10–300 °C. The ceramic heater heats the nozzle up to 300 °C.
PTFE tube (4 pcs)
The pack contains four PTFE tubes with the inner diameter of 2.5 mm and the outer diameter of 4 mm: 530 mm * 2, 30 mm * 2.
