Temperature on the mirror surface
Posted: Fri Feb 06, 2015 4:03 pm
Hey guys,
I'm finally at the point where I sourced most of the parts for my bottom-up DLP and am currently working on part after part. I'll be printing a lot of elements in PLA (where it makes sense) as I don't have a CNC router available.
Right now I'm making some first drawings for a 45° (or maybe adjustable) mirror mount, but I was wondering if I should be worried about the temperature on the mirror. Obviously the projector (Acer) get's pretty hot, but will the mirror just deflect everything and stay around air temperature? Of course I could cool it from behind, but if the mirror is above 70°C most of the time I'd probably be better off going with a AL construction right away.
Could someone with a mirror build give me some insight? Anyone using PLA or ABS parts as mirror mount?
Thanks!
