Filament Meter

Measure filament color directly from a TD1 or TD1S sensor on Mac, or from a TD1S on iPhone. Filament Meter turns live sensor readings into a practical, searchable filament library: • See transmission (TD), HEX, and RGB values as you scan. • Save measurements with a name, brand, material, display color, and notes. • Keep recent readings available after restarting the app. • Enter any HEX color to rank saved filaments by match percentage. • Search your library and export it as CSV. • Calibrate the sensor from the Mac app with guided sensor and black/white routines. On iPhone, connect a TD1S directly by USB-C. TD1S firmware 2.0.1 or later is required. Calibration is available in Filament Meter for Mac. Your measurements and filament library stay on your device.
