Designing an SLA printer

Hi there,

I am busy designing an SLA printer , I have all the electronics already to build my 6k 12.8" mono printer. I have a small problem with the LCD, it is only 1.25mm thick, so I need to put it on a piece of glass to support it. What is the thickest you can go with the glass?

I have a UV light source that is quite strong and that delivers the light at nearly perfect 90degree straight up. Does anybody have some input into my design please.

Regards

Nic

Hi Nic,

if the light points exactly 90deg upwards and is far enough from the LCD, then the "image" would be sharp enough for some Millimeters ... the limiting factor is the "fuzzyness" on the corners or single pixels ...
