Researchers develop technique to bend light around corners using 3D printing

Researchers at the University of Glasgow have developed a new technique to bend light around corners. This discovery involves a unique type of light scattering that mimics how materials like snow and clouds diffuse light. The team created 3D-printed objects from an opaque white material, incorporating clear resin tunnels. Light travels through these tunnels and scatters, allowing it to bend around corners in a controlled manner. While this method is less efficient than fiber optic cables, it is cheaper and simpler to produce. This advancement could have significant applications in various fields, particularly in medicine.
