4D Printing

Posted on Updated on

4D printing or 4-dimensional printing is similar to origami. 4D printing has the same technique we use in 3D printing. 3D printing is through computer-programmed deposition of material in successive layers to create a three-dimensional object.

4D printing adds the dimension of transformation over time. After fabrication, the printed product reacts with environmental parameters (humidity, temperature, etc.) and changes its form accordingly. The ability to do so arises from the near-infinite configurations at a micrometer resolution, creating solids with highly engineered molecular spatial distributions.

4D printing is a relatively new advance in bio-fabrication technology. Rapidly emerging as a new thing. Such as bio-engineering, materials science, chemistry, and computer sciences. 4D printing uses ultraviolet light to cure the layered materials after completing the printing process. Most 4D printing systems utilize a network of fibers that vary in size and material properties. The fun part of 4D printing is “Stress Relaxation.”
