¶ Batch Number Query Method and Explanation
The batch number can be used to query the production batch information of a roll of filaments. When there are process issues with the filaments, the batch number can help trace back to the source.
On the right side of the label, there is a code, which is the filament batch number, as shown in the image below.

Some early filaments may not have a batch number applied, which is normal. If there is no batch number, it is recommended to query the filament SN.
¶ Filament SN Query Method and Explanation
¶ Filament SN Explanation
The filament SN can be used to query detailed information about the filament. It is recorded in the filament RFID chip and can be read via AMS/AMS Lite. There are two types of SN stored in the RFID chip:
- RFID Chip SN: This is written by the RFID manufacturer during the production of the RFID chip;
- Filament SN: This is written during the production process of the filament.
The lengths of the two SNs differ; the RFID chip SN is shorter and is usually displayed on the printer screen or Bambu Handy, while the filament SN is longer and is typically displayed in the Bambu Studio. Both formats of SN can be used to find the corresponding filament. The formats are as follows：
- RFID Chip Format Example: DAB427B900000100
- Filament SN Format Example: 517322F08F084C6CA9D61CFFEDDFOA32
¶ Filament SN Query Method
¶ For users with AMS/AMS lite
If the user has AMS/AMS lite, they can read the filament SN through AMS/AMS lite. The specific method is as follows：
- From screen:
- From Bambu Studio:
¶ For users without AMS/AMS lite
Since the filament SN is written in the RFID chip, it cannot be read without AMS/AMS lite.
¶ Filaments without RFID chips：
The following filaments do not have RFID chips due to their softness/brittleness and are therefore not compatible with AMS, making it impossible to read the SN:
- TPU 95A HF
- PET-CF
- PA6-CF
- PPA-CF
- PPS-CF
These filaments are also not marked with RFID in the store.
