## What it is
A community research guide documenting how to decrypt, read, and clone the NFC/RFID tags Bambu Lab uses on its 3D printer filament spools, including Python key-derivation and Proxmark3 recovery scripts. It also serves as a hub for collecting and comparing scanned tag data from the community.

## Use cases
- read bambu lab filament nfc tag data
- decrypt rfid tags from 3d printer spools
- clone a bambu filament tag with proxmark3
- understand what data is stored on bambu rfid tags
- derive mifare keys from a tag uid
- contribute scanned filament tags to a community library
- reverse engineer the bambu ams rfid board

## When to choose
- you own a Proxmark3 or similar RFID tool and want to inspect Bambu Lab filament tags
- you want to clone existing filament spool tags
- you are researching the tag data format or the printer's RFID board
- you want to contribute tag scans to the community tag library

## When to avoid
- you want to create custom tags with arbitrary filament data - tags are RSA-signed and the printer rejects unsigned ones
- you need a turnkey product rather than a research guide with manual steps
- you have no RFID hardware and only want to read tags with a phone

## Facets
- artifact type: learning-resource
- maturity: active
- function: reverse-engineering, security, cryptography, developer-tools
- domain: hardware, reverse-engineering, security, developer-tools
- platform: windows, python, cli
- tags: rfid, nfc, 3d-printing, bambu-lab, proxmark3, filament-tags, documentation, hardware-hacking, linux, macos
