Researchers at the Massachusetts Institute of Technology are developing a so-called "4D printing" technology, which will allow large-scale 3D printed parts to be assembled by themselves in accordance with a predetermined structure and appearance mode. The emergence of this technology will likely completely subvert the traditional manufacturing industry in the future. Sina Technology News June 7, according to the report of the American Exploration Magazine website, 3D printing began to show a boom around the world, but the relevant technology While the positioning is still unclear, some people have already entered the next stage.
Researchers at the Massachusetts Institute of Technology are developing a so-called "4D printing" technology, which will allow large-scale 3D printed parts to be assembled by themselves in accordance with a predetermined structure and appearance mode. The emergence of this technology will likely completely subvert the traditional manufacturing industry in the future, making it easier for manufacturing operations in some harsh environmental conditions, such as outer space. Traditional industries will become difficult and expensive under the extreme environment of outer space.
The development of this technology was led by Skylar Tibbits, director of the MIT Self-Assembly Laboratory. 4D printing technology involves the application of special materials that change their shape when they sense motion, or are exposed to water, air, gravitational fields, magnetic fields, or temperature changes. The fourth dimension mentioned here refers to this "self-assembly behavior" of the material.
In the most recent TED talk, Tibis disclosed a project in collaboration with 3D printing company Stratasys.
He said: "In essence, 4D printing is actually 3D printing using composite materials. In this way, you add a function, that is, deformation." He said: "This is like a robot, but without wires and motors. . "
Tibis also showed at the scene that samples of materials printed with 3D printing technology of composite materials deformed into "MIT" after being exposed to water. Tibis said that this is the first time that people have internally added the property of deformation into the material body itself. The researchers used a special Autodesk software to simulate and optimize how and when the materials used deformed. He said: "We can use this software to design nanoscale microscopic self-assembly systems, as well as human-scale large-scale self-assembly system design."
Tibis also revealed that the MIT Self-Assembly Laboratory is working with a Boston-based company called "Geosyntec" to develop innovative infrastructure pipeline manufacturing solutions. He said: "Imagine this new type of underground water pipe, which can expand or contract freely, in this way to control the flow and flow rate of the passing water, or it can be squeezed by its own peristalsis like a snake to push the internal Water flows. The pipelines with this incredible function are not expensive, and do not need those complicated valve control systems. This is inherent in these pipelines, and it has its own properties. "
Just like 3D printing in the traditional sense, 4D printing is not yet mature. However, developers at the Massachusetts Institute of Technology ’s self-assembly laboratory believe that this technology will eventually bring revolution in the fields of biological science, material science, software, robotics, manufacturing, transportation, infrastructure construction, construction, art and even space exploration Sexual changes.
Using Dog Gate to protect your baby from the pet dog and stairs. It has two locks to privent your baby opening the gate easily.Because of the steel material,so it is durable.With the extension bars,you can put it on different widths of doors.
The Advantage of the Safety Gates:
1. Great for closing off doorways, hallways, and stairs.
2. The safety gate is also easy to install.
3. Protects children and pets from potential in-home danger.
4. Swings open in both directions and closes automatically.
