3D Printing ????  There is so much more that can be implemented with the use of 3D materials in print to amplify their value. These processes will enable these materials become more elastic and increase their functionalities. The materials produce a change in a planned automated way. Their repeated alteration over time resulted in major advancement known as 4D printing which is more advanced than 3D Printing .

The new technology, 4D printing involves the addition of a new element to the advanced 3D printing process by the design to transform shape after it leaves the print bed. 3D Printing  has been here for a while, 4D printing has been under development for a while now. It has drawn the interest of a good number of researchers in the world. This is common with researchers in fields relating to printing and the likes.

Various printable materials change in their forms on exposure to elements like high temperature and water.  Most 4D printing research has depended on the utilization of hydro gels. Hydro gels are advantageous because of their soft nature. This is responsible for their complexity in the preservation of their natural forms after alteration.

The latest research from Georgia Tech, Xi’an Jiatong and SUTD postulates that it is most likely achievable to develop 4D printed Objects that undergoes irreversible transformation. This finding signifies innovation in 4D printing technology.   This research was published in the academic journal Science Advances.

The printing of the 4D material involves 3D printing layers of shape memory polymers. Each layer is positioned to differently on heat exposure. Shape memory polymers are particularly intended to retain information concerning their original profile and to changNew work out of Georgia Tech promises to lend a sense of permanence to shape-shifting 3D printing. The technology, commonly referred to as by those in the know, aims to add another dimension to the 3D printing process by creation an object designed to change shape after it leave the print bed.

Most models from research institutes like Harvard and MIT have relied on hydrogels to execute the process. The soft materials execute the functionality slowly and don’t retain their shape after the process is completed.
