 FilaMan ist ein Filament-Managementsystem für den 3D-Druck. Es verwendet ESP32-Hardware für Gewichtsmessungen und NFC-Tag-Management. 
 Benutzer können Filamentspulen verwalten, den Status des Automatic Material System (AMS) von Bambu Lab Druckern überwachen und Einstellungen über eine Weboberfläche vornehmen.
