Printing Fiber Preforms

Caption

Researchers used a 3D printing method known as direct-light projection (DLP) to make silica fiber preforms. They fabricated preforms for a step index fiber (a) and a structured preform (b). These preforms were then placed in a draw tower (middle picture) to make the final optical fiber (right). The orange inset shows a cross section of a step index fiber.
