Tell us about yourself!
If you work with MakerBot, "negative" mold will produce textural artifact, that is not always desirable in the final product. 2-step process takes care of that part. "Negative" mold approach will work beautifully with other, more advanced, printers like FormLabs that use resin. The objects come out smooth with no visible artifacts, and you also have the ability to make your mold flexible, but, unfortunately, these printers are more expensive to print on and not as widely available. You can make flexible molds with MakerBot using ninjaflex material, but, in my experience, the molds are always more fragile.
