The illustration shows how the ultra-thin spread filament tapes are arranged in layers and then thermomolded into a sail. Each color represents a different ply (layer ) comprised of filament tape(s). The tapes can be any length and oriented in any direction, allowing unprecedented precision in matching sail structure to predicted loads in the sail. Note that all reinforcements in a 3Di sail (blue layers) are applied as an integral (internal) part of the sail laminate.
With 3Di technology, designers have such precise control over the disposition and orientation of material within the sail, they can come far closer to achieving the holy grail of sailmaking... BALANCED RESISTANCE TO DISTORTION IN ALL DIRECTIONS.
