Abstract
4D printing is a technique that uses a 3 D printer to create objects that change their
shape overtime 4 D printing involves the use of smart materials that will transform when
exposed to an external stimuli These can include water, heat, light or electric current
4 D printing technology is still in the early phase of research and development 4 D printing
is currently being developed by industry leader and research facilities such that of MIT’s
Self Assembly Lab, Stratasys and Autodesk Overall, 4 D printing is making the object
‘ while executing their ‘genetic code’ whenever you want to have it triggered
