Build Your Own SLA/SLS

I'm still trying to figure this out. From what I have read the Acer H6510BD (1920x1080 pixels) has a transparent (white/clear) color wheel segment (RGBCMY) which I think allows more specified lumen output. I'm guessing that the transparent (white/clear) segment is why you don't need to remove the color wheel. But the color wheel has only 6 segments, so I don't know where the clear segment comes from.

and Acer SpectraBoost offers a wider color gamut via a patented color-wheel coating, which boosts color saturation an extra 30 percent.

I'm curious if the coating on the color wheel is blocking UV?

RGBCYW has greater lumen output than RGBRGB

single-chip DLP projectors sometimes include a white (clear) segment in the color filter wheel to increase the peak white level, and some filter wheels also include segments with one or more of the secondary colors (yellow, cyan, magenta). Therefore, when you add the maximum levels of red, green, and blue, the result is lower than the measured peak white level, because those extra segments are not used in the RGB measurements, whereas they are used in the white measurement.

thanks alot, i´ll try to get my hands on one of these.

I still wanna know which projector is the best choice for a DLP printer?

I really don't think there is such thing as "best projector", each projector will fit better to a specific combination of resin/size/etc. But i do believe that h65 seems a good choice.

Thanks, I will try it.

I have an Optoma EP758 (1024x768 -- I know, I know)

I want to replace the lamp with a UV LED. I've been trying to figure out what I need to ground/bridge on the lamp driver module connector in order for the projector to think the lamp is still in the machine and working.

Any ideas?
