Proceedings Paper

A comparison study of laser based additive manufacturing techniques applied to chalcogenide glass (Conference Presentation)

Paper Abstract

Additive manufacturing has taken many industries by storm, bringing a revolution to prototyping and manufacturing lines. For the most part, Glass and Optical Materials have been left on the wayside during this insurgence of additive manufacturing. Initially, the processes had very significant barriers to create practical uses for glass and optical materials. The emergence of UV curing or crosslinking polymers from a bath has proven useful for some optical elements and component applications for organic polymers. The majority of inorganic glasses are already fully cross-linked and cannot be used in curing/crosslinking methods. Rochester Precision Optics (RPO) is constantly developing and designing optical elements and assemblies, having a cheap and quick process to prototype optics for demonstrators and initial prototype systems would be extremely valuable. RPO has investigated a number of methods to incorporate additive manufacturing of glasses into the optics and photonics fields. Laser based approaches of additive manufacturing of chalcogenide glasses will be presented. Optical properties and performance is compared across various additive manufacturing approaches and compared against bulk traditional material and processes.
