Example monofilaments include “ microprinted ” monofilaments that contain an arbitrary image embedded in the monofilament cross section ; microfluidic monofilaments in which flow channels are formed by combining optically transparent and opaque materials ; dual-material monofilaments that combine ABS and polycarbonate into a regular spoked geometry with five-fold symmetry ; and a microfluidic preform co-fed with glass optical fiber , allowing both fluid and light transmission through the monofilament .
