Build Your Own SLA/SLS

I really want to get this to work but so far it's proving to be a bit futile.

I notice the first few exposures are fine and i get adherence to the build plate. I think a quarter of the way through the whole build process, the print comes away from the build plate rendering the rest of the print useless.

I'm not getting this with B9 yellow it's only the waxcast. Is the waxy content making it less sticky? Anyway of getting good prints with this stuff?

Try longer exposures for the first couple of layers. Another thing you can do is scuff up your build platform to give the part more adhesion to it.
