The emergence of “4D printing”
Imagine things can replicate by itself an appropriate design. In my opinion, we need 4D printing to make water pipes for snowing region.:)
MIT researcher Skylar Tibbits works on self-assembly — the idea that instead of building something (a chair, a skyscraper).
He is an artist and computational architect. Skylar Tibbits is working on “smart” components that can assemble themselves.
3D printing has grown in sophistication since the late 1970s; TED Fellow Skylar Tibbits is shaping the next development, which he calls 4D printing, where the fourth dimension is time.
This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time.
Think a printed cube that folds before your eyes, or a printed pipe able to sense the need to expand or contract.
Polymer based 3d printing from Carbon3D
Carbon3D has announced a new approach to polymer based 3D printing. Their approach is based on CLIP (Continuous Liquid Interface Production) technology which continuously grows objects from resin instead of the conventional approach of layer by layer printing. Joseph DeSimone, co-founder of Carbon3D and Chancellor’s Eminent Professor of Chemistry, UNC, mentioned in his Ted talk in Canada, that this technique was inspired by the film Terminator 2, in which the T-1000 robot rises from a pool of metallic liquid. According to DeSimone, objects created by conventional 3D printing are weak because they are made up of multiple layers obtained by 2D printing over and over again. In contrast, CLIP based 3D printing is 25-100 times faster and generates much stronger objects.
