2. Product Overview
BIQU Vault is a modular smart filament management rack designed for 3D printing filament storage and
inventory management. The system consists of a main rack and optional expansion racks. The main rack
integrates control, display, weighing, NFC identification, local storage, and communication functions, while
expansion racks add filament storage bays, bay status detection, and position guidance.
Users can register filament information through weighing and NFC identification. After filament is placed in an
individual storage bay, the bay trigger detects its occupancy status. When locating filament, the system provides
position guidance through rack-level and bay-level indicator lights. One main rack can connect to up to three
expansion racks.
3. Key Features
Modular expansion: One main rack serves as the control center and supports up to three expansion racks.
Independent bay detection: Each storage bay uses a trigger switch to detect occupied/free status.
Filament weighing: The main rack includes a weighing area with a maximum capacity of 2 kg and 1 g
resolution.
NFC identification: Reads compatible filament tags for filament identification and inventory management.
Position guidance: Rack-level and bay-level indicator lights help users quickly locate target filament.
5-inch touchscreen: Used to view device status, manage filament, and configure basic system settings.
Environmental monitoring: Built-in temperature and humidity sensors record the environment around the
rack.
Local storage and peripheral interface: Supports local storage on a TF/microSD card and provides a USB port
for compatible peripherals or USB flash drives.

If the weighing platform does not display zero when unloaded, press the TARE button to zero/tare the scale. Place
one filament spool steadily in the weighing area and wait for the reading to stabilize before registering or storing it.
BIQU Vault User Manual • 10
Do not exceed the 2 kg weighing capacity, and do not drop or throw filament onto the weighing platform from a
height.
8.2 Filament Identification and Storage
Typical workflow: Identify/weigh filament -> system confirms the filament -> place the filament in an available
storage bay -> the corresponding bay trigger switch activates -> the system records the bay status. Bay detection
includes delay/debounce logic; specific prompts and timing parameters depend on the current firmware version.
8.3 Removing Filament and Position Guidance
After filament is removed from a storage bay, the bay trigger switch is released and the system determines the
actual removal status according to the configured delay parameters. When locating filament, the system can
indicate the target position using rack-level and bay-level indicator lights. The lights are for position/status
indication only and should not be used as the sole basis for device fault diagnosis.
8.4 TF Card and USB
