Nowadays, 3D printing technology has set off a craze all over the world, and while people are gradually accepting it, some people have already begun to enter the next stage of research.
According to reports, some researchers in the United States are developing a “4D printing” technology, which will allow large 3D printed parts to be assembled by themselves according to preset structure and appearance patterns. The emergence of this technology may completely subvert the traditional manufacturing industry in the future, making manufacturing under some harsh environmental conditions easier.
4D printing technology involves the application of special materials. These materials will change their shape when they sense motion, temperature changes, or are exposed to water, air, gravity fields, and magnetic fields. The fourth dimension here refers to This “self-assembly behavior” of materials. 4D printing is essentially 3D printing using composite materials. In this way, a function is added, which is deformation.
The researchers demonstrated a material sample printed by 3D printing technology using composite materials at the scene. The sample can deform into the words “M-I-T” after being exposed to water. The property of deformation is added to the material body. Researchers use a special Autodesk software to simulate and optimize how and when the materials used deform. For example, this software can be used to perform nanoscale microscopic automatic Assembly system design can also be used to design large-scale self-assembly systems at the human level.
4D printing technology is not yet mature, but developers at the MIT Self-Assembly Laboratory firmly believe that this technology will eventually bring about biological sciences, materials science, software, robotics, manufacturing, transportation, infrastructure construction, and art. and even revolutionary changes in space exploration.
