Fleet Hub connects up to 50 Bambu Lab printers on one wired local network and exposes them through a certificate secured HTTP API, so you plug them straight into your own ERP, MES or PLM system. Bambu Lab positions the device as the bridge between 3D printing and digital manufacturing, while All3DP's in-depth review concludes Fleet Hub is built for businesses and developers writing their own software, not for running a print farm out of the box.
Once activated, Fleet Hub runs fully offline: models and camera snapshots stay inside a 40GB local only cache, with zero outbound traffic to Bambu Cloud. Full technical and security documentation, including the Technical White Paper and Security White Paper for developers, is available on Bambu Lab's official Fleet Hub page.

Fleet Hub manual (Bambu Lab Wiki) |
Once a printer is bound to Fleet Hub, it disconnects from Bambu Cloud, so Bambu Handy cannot be used on that printer at the same time.
