The technical name for a shape that can be made from a flat plane via cutting, folding and bending but without stretching or compressing is a developable surface-

Cylinders, cubes, pyramids and cones are basic examples, and with computers extremely complex shapes can be segmented and unfolded to create patterns for 3-D objects.

Curved creasing/folding (see pic) is another option that can develop amazing shapes with minimal cutting and assembly work
