3D printing is the current hype in the tech world. People are amazed with the ability to print their imagination in 3D and do all kind of stuff with it. Its a boon for artists and innovators. While the world is looking to expand the horizon of 3D printing, there is a group of people who are thinking about 4D printing.
4D printings adds the dimension of time to materials i.e. programmable materials which can self assemble or disassemble in real time depending on the type of stimuli. The idea of 4D printing comes from shape memory alloys which used thermoelastic displacive transformation like thermoelastic martensitic transformation to change shape with stimuli.
But advances in 4D printing is going to herald a new era of materials that can build themselves. The MIT's Self Assembly lab is working on the technology of 4D printing. They are currently printing interwoven materials with different thermal properties thus on exposing to temperature change they tend to behave similar to shape memory alloys.
