123D Sculpt+

Autodesk’s fantastic iPad app lets you create 3D sculptures like a pro. Choose a shape from the included collection (or import your own, or even buy new shapes in-app) and manipulate them to your heart’s content using the app’s extensive array of tools. If you like your sculpture you can take photos, create animations or even export your creation as a 3D file you can then create with a 3D printer.
