This is a general introduction to developing SLA (Resin) based 3D Printers. And something to watch if you are involved with the OpenSLA project over on Google+
Check out all the great development - https://plus.google.com/communities/1...
And please share and get involved too - Thanks.
I made this video a little while back, and things are moving on fast, so expect more updates - and please ask questions and say what you would like to see talked about, for future OpenSLA video's or chat.
