Color Transparency Calibration and Test with 4 filaments. Test plates designed to see the effects of all four color combinations with 7 levels of thickness. Thickness of layers are 0.1mm, 0.2mm, 0.3mm. 0.4mm, 0.6mm. 0.8mm, and 1.0mm. Each test plate is the size of a standard business card (89mmx51mm).

Each filament and filament brand has different light transmission characteristics. Some applications desired high transparency, while those involving text and other high contrast detailing prefer low light transmission. Many possible 4-color combinations are possible. The examples shown use the filaments of the Bambu PLA C-M-Y-K bundle.
