Shape-shifting '4D' printed objects could pave the way for outer space structures

It takes a lot of money to launch stuff into space -- even by NASA terms. The cost ranges from around $9,000 to more than $40,000 per pound. With that sort of price tag, weight and space are at a major premium with shuttle missions, causing NASA to look for innovative new ways to create more compact payloads. A team at Georgia Institute of Technology is exploring a method that uses 3D printers to create small structures that expand when expose to heat that might some day help with the problem.
