I regularly cast resin figures. At present I use silicon molds. I am considering if it would be possible to print with my Peoplay Phenom using a flexible resin and create a negative mold from my figures .STL I now know how (I think) to slice and split files.

But how do I inverse the selection thus creating the negative space of the figure. So to print the space around the figure leaving a hollow figure space in the middle?

Thank you. You are all amazing and so helpful. In return I intend to sculpt some cool figures, get them scanned and release them for anyone to print if you so wish.
