Build Your Own SLA/SLS

Hi All,

I have an issue of uniformity of light on the build plate, and i read that could be solved with a Mask, could anyone please guide in the process to apply a mask? and where can i download it?

Thank You

Here is one that I have used before for sensitive resins...
You make the masks using a photo editing software of your choice.
