Researchers at Arizona State University have invented a method of manufacturing GDVN using two-photon laser lithography. By appropriately tailoring the intensity and duration of the laser pulse, sub- micron resolution becomes relatively routine, and feature sizes as small as 50 nm have been reported. Moreover, it is a true 3D fabrication technique, capable of “writing” any desired voxel within a specified 3D volume. Standard 3D fabrication techniques complete projects by building structures one layer at a time, requiring the motors to constantly switch between mechanisms. This invention uses fast writing mechanisms to form each block separately, minimizing mechanical switches and production time.
