Mandrea,
do you have a Fresnel lens below your LCD module? Are there advantages?

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

50W led mod for the printer. Huge fan and fresnel lens, 50W led driver. Done a test with Funtodo IB at 50 microns, the layer time is down from 10 sec to 5 sec.

This is the fan+lens:

https://www.aliexpress.com/item/10W-20W ... 0.0.1hxgpK50W Led:
https://www.aliexpress.com/item/High-Po ... 0.0.1hxgpKI'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.
