P1P

The P1P is an FDM 3D printer from Bambu Lab with a 256 x 256 x 256 mm build volume.

Specifications

Hotend: The P1P uses an all-metal, all-in-one proprietary hotend where the nozzle is integrated directly into the heat block [1, 2]. It operates at 60W and is capable of reaching a maximum temperature of 300°C [4, 5].

Bed: It features a magnetic, heated bed equipped with a textured PEI spring steel sheet [4, 6]. The maximum bed temperature is cited as 100°C in its standard specifications [7, 8], though one comparison source lists it at 120°C .

Chamber: The P1P is an open-frame printer, meaning it does not have a heated or enclosed chamber out of the box [10, 11].

Build Volume: The maximum printable area is 256 x 256 x 256 mm (10 x 10 x 10 inches) [4, 5, 7, 12].

Calibration

Step 1: Bed Leveling & First Layer Calibration

• Action: The Bambu Lab P1P comes pre-leveled from the factory and utilizes an Automatic Bed Leveling (ABL) system using sensors [1, 2]. You simply need to ensure the automated bed leveling check is enabled before starting a print . Manual tramming with the three knobs underneath the bed is only necessary if extreme issues arise . There is no need to manually set the Z-height or Z-offset .

Common defects

Defects & Bugs

• Thermal Runaway Protection Delay (Firmware Bug)
• Symptom: In early versions of the P1P, if the thermistor failed or gave abnormal readings, the printer would wait up to 3 minutes before cutting power and sounding an alarm, posing a fire hazard .
• Cause: Bambu Lab initially programmed a 3-minute delay to prevent false positive readings while users were performing maintenance on the hotend .
