DLP670S: Early DLP DMD failure under 385nm illumination and 24/7 use

In our testing we are experiencing very early failures of the DLP DMD chip with 385nm UV light in industrial 3D printing application and we want to understand 1. failure modes of this chip in the 385nm environment 2. which chips are best to operate 24/7 with 385nm 3. How can we mitigate failure so the chip can last 10k hours? (I am asking this since our light engine manufacturers are having life challenges and we are deciding if we should build our own light engine and source from TI).

How can I talk with a Ti expert about the DLP DMD chips to see how we can design the right environment for them to last 10k hrs at 385nm UV environment? thermal, electrical, duty cycle, etc

technical specifications, known failure modes, environmental requirements to improve life, etc

Most likely it is the failure of the light engine design (I'm thinking of heat sinking) but want to understand the DLP chip failure mode when illuminated with 385nm.

Our industrial 3D printers run 24/7 and each layer is illuminated with 385nm UV light from the DMD chip.

We are deciding to make our own light engine with a TI DMD chip or to help our suppliers to improve their design to improve the Ti chip life to get the proper guidance,

let me know if it possible to talk with a technical DLP DMD expert,

thank you
