These tiny objects made with 3D printers can dramatically expand when exposed to heat.
Scientists have created a pair of compact, unfurling structures that could pave the way for innovations in biomedical devices or space exploration, where payloads can cost tens of thousands of dollars per pound.
A team at the Georgia Institute of Technology crafted these objects using "tensegrity" — a structural system of floating rods in compression and cables in continuous tension. Researchers crafted the rods and cables, called "struts," from shape memory polymers that unfold when heated. Read more...More about Space, Science, 3d Printing, Georgia Tech, and 3d Printing In Space
