To build medical-grade silicone implants, a mandrel is coated with liquid silicone and air dried, a step that is repeated 10 to 15 times. Today, this process wastes about 75 percent of the raw material, which drips off the mandrel before it can dry. Our approach uses two narrow bands of light; one band stops the material from moving and the other allows deep drying and curing of the silicone. Today, curing is a slow process with forty minutes or more between coatings which dry from the outside in, trapping solvents. Our new light-based process dries silicone rapidly from the inside out in seconds. Manufacturers save material, time, and money—while increasing product quality.
