Researchers manage to fabricate a flexible OLED device using only a 3D printer

Researchers from the University of Minnesota Twin Cities managed to deposit flexible OLED devices using 3D printing. The whole OLED stack (including the electrodes, interconnects, insulation, and encapsulation) was printed using a table-top 3D printer (custom build, and reportedly costing like a Tesla Model S).

The researchers used the new method to create a low-cost flexible OLED display of sort, made from relatively large pixels (see video above). The whole panel is 1.5 x 1.5 inch in size, with 64 pixels. The team is now working to improve the density of the process.

But why?

I think there could be interesting use cases, of embedding simple OLED lighting or display panels as part of 3D printing settings.
