Build Your Own SLA/SLS

Any of you had any incident with the backlight of the projector.

I am using resin fun2do brand and always get similar results. backlight on projector cure thin layers of resin and everything breaks down.

I have adjusted the projector settings to hiest contrast and lowest brightnes, but I still have problems.

any recommendations will be welcome. thank you very much.

Solved!!!

I bought a variable Neutral Density filter and install to the projector lens.
So i can turn more or less bright, depend on the resin sensibility.

But dont install close to the projector lens or will burn the filter.

Glad you fixed it. I will just throw this out there in case anyone has the problem that I did. I let the projector auto-adjust when I first got it. For some reason the brightness was cranked up to 93%. I manually lowered it to 30% and all was good after that.
