This company has developed very tough SLA resins and are apparently selling them already. Although they seem to work only with their printer.

Worth watching this video:

Interesting graph at 22' 20"

I hope it's just a matter of months till we can purchase materials like this and print them reliably on our printers. Future looks cool for SLA.

Edit: in the Q&A session at the end of the video he seems to imply they are also going to sell some products to the maker community. Cool.
