4D Printing

Hello steemians, in this short article We will discover the 4D printing , new technology , that Very little known, I tried to shorten and simplify the information so please Upvote if u like my work and follow me to support and encourages me to do more,

First of all Let's remember the 3D printing (or additive manufacturing)

this technology turns digital blueprints to physical objects by building them layer by layer. is 30 years old this year. Today, it’s found not just in industry but in house also, as the price of 3D printers has fallen below 500 dollars. you can print almost anything, opens up unlimited opportunities for us to manufacture toys, household appliances and tools in our living room.

4D printing is based on 3D printing . With one big difference: It uses special materials and sophisticated designs that are “programmed” to prompt the 3D print to change its

In simple words, 3D printing is the next step in the evolution of 3D printing which adds the dimension of time to the traditional 3D printing process. This means that through 4D printing, a 3D printed object can change its shape after it is printed, in response to water or heat.

In the following video we see a flat-printed structure that, once placed in the water, slowly folds itself into another structure. The video below is a test from MIT Lab demonstrating the functionality of shape transformation:

Advantages of 4D Printing:
The most obvious advantage of the 4D Printing technology is the usage of the possible applied materials. 4D printing has a vast potential to revolutionize the world of material as we know it today. Imagine 4D printing being applied to a variety of smart materials that today we cannot even imagine! Until now, we have seen experiments of Multimaterial Shape Memory Polymers. Materials like the ones featured in the video below, “remember” their shape, actively transforming configurations over time in response to environmental stimuli.

I hope you learned something new from this short introduction ,
