Build Your Own SLA/SLS

Hi Community, I happened across your forum quite by chance, saw a few pictures and now I am hooked.

I have a bit of experience in these kind of projects having in the past and quite fancy building my own printer.

Is there a single online resource anybody could direct me to as a primer in self-building which the community regards as a good resource?

I am looking for design choices and detailed build guides.

Finally I have read some (probably poorly informed) advice that the resins are very toxic? Is this the case, and what precautions if any do you guys follow?

Thanks, Al.
