I have a Cricut explore one, is there any way to use it with fondant or gum paste ?
I've done it. You need to get whatever you want to cut in an SVG format (you can use Illustrator or an online converter). Also get a Cricut Cake mat and rub a little shortening on it. Roll your fondant to a 6ish on a pasta roller and experiment with the pressure settings and the deep cut blade. Keeping the fondant cold is imperative. Freeze it before cutting and again after to make it easier to lift shapes from the mat.
I have a Cricut explore and was thinking the same thing. I contacted Cricut and asked them and was told it is not safe for use with food. They used to sell the Cricut Cake that is for fondant/gumpaste use. But I don't think they make them anymore, so they're very expensive.
I don't know what part of it wouldn't be okay to use for gumpaste, since the only part that would touch it would be the blade sand that's the same as the ones that they use for the Cake Cricut. But I find an exacto is faster and better than the cricut once you take all the trial and error into account.
