Read it left to right: the chip identifies the spool; accessories capture reality (scans, weight, color); the apps and cloud keep it all in sync; the printer receives the filament data and reports back live. Your slicer keeps its job — TigerSystem doesn’t slice, it makes sure everyone (you, the machine, the apps) knows exactly which filament is where.

Design principles

The chip is self-sufficient. A spool identifies itself with no cloud, no account, no network — the payload is complete and open.
The cloud is the user’s, not the system’s. All state lives under the user’s account; server-side security rules — not client code — enforce access.
Every layer is optional. Phone-only, desktop-only, chip-only, or API-only usage all work; components add value but never gate each other.
Integrations speak the printer’s native protocol. No firmware mods, no cloud detours: Tiger Studio talks MQTT/WebSocket/HTTP directly on the LAN (see data flow).
