Mandrea,
do you have a Fresnel lens below your LCD module? Are there advantages?
5.5 inch (2560x1440p LCD) with UV LED array for under $600. :Proniks Sla 3d Printer,

Hallo,
@russiansgems, I saw a post from you with the lcd and a mikroskope picture with a crack.
Have you seen normal RGB colour filters? I do a litte research, how to modify LCD for UV-light and I think there are 2 possible uv-light filters in the LCD:
1. RGB color Filters wich filters other wavelengths
2. Materials with filter properties. Fore example some Polymers and glases filtered also UV-light. I found some informatione of an acrylic glas poylmere which is developed for terrariums.
I know you can not change a LCD production for some 3d printing guys so I am searching of possibilities to modify the LCDs. Maybe it is possibel to remove the RGB filters, but I think the glas plates are glued together.
Regards

Ok Folk,
the resin FTD Industrial Blend arrived,
I immediately put at work the "baby",
response: The printer would be exceptional if it had a more precise Z axis (see wedeling effect), I ordered an anti backlash to solve the problem
3 x burn @ 70 sec
normal @ 7 sec
0.025 micron

This is the fan+lens: http://www.ebay.co.uk/itm/252683611628? ... EBIDX%3AIT
Led driver: https://www.aliexpress.com/item/10W-20W ... 0.0.1hxgpK
50W Led: https://www.aliexpress.com/item/High-Po ... 0.0.1hxgpK
I've cut a bigger hole on the bottom to fit the bigger fan and added taller legs to allow for the extra space needed.
The image is a paper over the LCD, it is a bit uneven, but nothing too extreme.
