Like to have a chemical that expands quickly in to a specified shape and then can be easily removed from the shape and start again

Have a look for the "elephant toothpaste" trick. There are loads of videos out there.

Add vinegar and sodium bicarbonate(baking soda) and you get the classic erupting volcano. It that what you mean by expanding or stuff that foams up like polyisocyanurate spray on foam insulation. There are also polyurethane foam insulations too. They really are reactions that produce gases to make it foam.

even normal Gorrilla Glue does the expanding trick :-)
