Fabrication of Glass‐Ceramic 3D Micro‐Optics by Combining Laser Lithography and Calcination

This perspective is an overview of a recent direction in optical 3D printing, where polymerization crosslinkable materials and nanomaterial fillers can be guided to the final structures new composites via high temperature annealing (HTA). Defining nano/micro-structures by ultrafast laser direct writing tailoring their precursor composition with subsequent tunability properties during 750–1500 °C HTA step takes place at large surface-to-volume ratio conditions favoring efficient pyrolysis calcination, which are required for exchange chemical materials/gases between glass/ceramic phase surrounding. Previously, unexplored inorganic material formation terms fast thermal quenching, mixing surface tension harnessed glass making creation endowed preferable technical properties. An immediate application durability, integrated, active micro-optics foreseen.
