“The so-called 4D printing, more than a 3D printing, a “D” is the time latitude, people can set the model and time through software, the deformed material will be deformed into the desired shape within the set time. Accurately speaking 4D Printing is a kind of material that can be automatically deformed. It can be built directly into the material. It can be automatically folded into the corresponding shape according to the product design without connecting any complicated electromechanical equipment”—–quoted from Baidu Encyclopedia.

After years of development, I am sure that everyone is very familiar with 3D printing technology. At present, there are many civilian-grade 3D printing devices on the market that are relatively cheap, and some products produced by 3D printing technology are also on the market.
Throughout the history of human technology development, one of the most fundamental driving forces for its development is the liberation of human beings from all kinds of heavy labor. Because of the inconvenience of molding, 3D printing technology has been produced. So, have you considered that even with parts, assembly is still a complicated job. In order to further spread human “lazy cancer”, 4D printing technology came into being.
Popularly speaking, it is the production of parts with self-assembly through 3D printing and other technologies. When these parts are put together and provide the corresponding energy, these parts can be self-assembled without human intervention. More importantly, the external energy supply can be random energy, such as irregular shaking, such as sunshine, wind blowing and so on.
For example, the dark things in the bottle in the picture below look like some broken coal.
However, as long as you shake it hard, the “broken coal” inside will magically assemble itself to form a specific structure, and no matter how you shake it, it will eventually become the same shape.
Of course, this is just a simple demonstration, and the ultimate goal of its developers is to produce high-precision equipment that can be self-assembled, such as various equipment used in aerospace experiments.
In the civilian sector, this technology also has broad prospects. Imagine the following. One day you bought some furniture parts and went back. Unpacking the boxes, you just shouted three times at them, “Get up, get up,” (this is what I imagined, but the sound can also be considered as A kind of energy), then a table or a chair slowly appears in front of your eyes.
Is it amazing, is it black technology?
