Two photon polymerization (TPP) is a form of 3D printing that allows for the creation of microstructures below the standard diffraction limit by using two-photon absorption to have polymerization only occur within the focal volume of a laser. The current standard laser wavelength for TPP processes is 780 nm to take advantage of the fact that UV curable resins and lithographic processes are in abundance. However, this standardization also restricts the ability to engage with TPP as the most commonly used lasers are expensive Ti;Sapphire that are part of even more costly machines, Here we have shown the ability to customize a TPP process for a 522 nm wavelength laser and have implemented it on a standard optical table. By modifying the chemistry of a resin formula that has been proven to work for 780 nm processes we developed a resin optimized for 522 nm. This resin was then shown to be able to produce simple structures on a variety of substrates that are commonly used within the semiconductor and optical industries. With these findings, we show that a TPP process can be created that allows microstructures to be created on simple optical tables with less expensive setups. These findings lower the entry costs of TPP by allowing labs to use preexisting optical setups and lasers.

Dr. Blake Daiber completed his Bachelor’s degree in Computer Science from the University of Alabama in Huntsville in 2019. Driven by a desire to engage in hands-on research building quantum computing components, he enrolled in the PhD program at Auburn University. He is currently researching the development of integrated photonic chips that incorporate on-chip light sources and entanglement. His goal is to apply his research in the field of quantum simulation.
