IR-laser assisted additive freeform optics manufacturing

IR-laser assisted additive freeform optics manufacturing

Abstract Computer-controlled additive manufacturing (AM) processes, also known as three-dimensional (3D) printing, create 3D objects by the successive adding of a material or materials. While there have been tremendous developments in AM, the 3D printing of optics is lagging due to the limits in mat...
