3D printing technology is quickly revolutionizing the way we create optical components. Scientists at the University of Wisconsin-Madison have developed a novel method for 3D printing microlenses directly attached to material surfaces. This method, known as Facet-Attached MicroLens (FAML) Photonic Printing, has the potential to revolutionize optical devices and photonic systems. FAML Photonic Printing creates lenses that are much smaller than traditional lenses, allowing for more intricate and compact optical designs. The lenses can be printed on a variety of materials, including metals, plastics, and glass, with a range of focal lengths and lens shapes. This method offers a cost-effective way to create custom optical components with a wide range of potential applications.
