you can certainly do it as DIYer but to ameliorate it and commercialize it you are going to deal with patenting. SLA patents just recently started to expire and this has already created an explosion of new developments. see here for instance http://qz.com/106483/3d-printing-will-explode-in-2014-thanks...

you may also want to check to formlabs last year, and their litigation on the patenting.
