3D Printing Small Optical Structures

In summary, there are specialized 3D printers that are capable of producing small optical elements. Additionally, there is a company that creates light shaping diffusers for lamps using microscopic structures on the surface of their diffuser film that control light through interference patterns. They offer free samples and their process involves using a photopolymerizable film with an index matching fluid, specifically the DuPont HRF700X318 photopolymer. The method for creating their surface bumps is not clear, but it involves chemistry as described in their patent.

Specialized 3D printers can now produce small optical elements:
Described here.

There is also a company that makes light shaping diffusers (for lamps) that control the light by controlling the interference patterns of the light due to microscopic structures on the surface of the diffuser film.
(You can get free samples from them.)
Its not clear how these guys made their surface bumps, probably not 3D printing, yet.

Looks like they're using DuPont HRF700X318 photopolymer.
