Is it possible to convert a 3d model in .stp format into a mold for casting that can be printed? the file is perfectly within allowable geometry a mold would allow, i cant remake the model from scratch in an inverted format, the dimensions are way too specific, i need some sort of function that will do it. i use autodesk inventor and i am pretty sure there is no way to do this in inventor without a total rebuild. If there is another program out there capable of this please share. i know i could just make a mold of the model in a casting medium but some details are way to small to be molded with latex or plaster or silicone.
Thanks in advance
