I have machined it in as little as 3 hours or so but, it usually sits for 24 hours before I get to it. It gels in about an hour.
I use ETI polyester resin. If you need quicker cure times, take a look at urethane resins. Some have a pot life of 20 minutes and less. I think they still reccomend a 24 hour cure.
