According to foreign media reports, at present, researchers at the Massachusetts Institute of Technology are developing a "4D printing technology" that can self-assemble macro-level 3D printing materials into a definite structure and appearance according to pre-programmed procedures.
The newly developed 4D printing materials can deform and self-assemble
This technology will potentially change construction and manufacturing, making it easier to construct environmental spaces, such as constructing space infrastructure. The harsh weather conditions in space will cause construction costs to be expensive and dangerous. Skylar Tibbits, director of the MIT ’s self-assembly laboratory, is the project leader. He pointed out that the materials used in the 4D printing process can change shape and can respond to contact with water, air, gravity, magnetism or The fourth dimension of temperature change refers to the ability of the material to self-assemble.
At the recent TED conference, Tibitus showed this latest project in cooperation with Stasi 3D printing company, he said: "4D printing technology is a new deformability on the basis of 3D printing diverse materials , It ’s like a robot without wires and engines. "
Tibbetts demonstrated that the 3D printed "smart material" will fold to form the letter "MIT" structure when it is in contact with water. He believes this is the first time to realize the self-deformation of the directly embedded material. When and how to fold the material. He said: "We can use the same software to design nanoscale self-assembly systems, as well as human-level self-assembly systems."
At the same time, Tibitus stated that the Self-Assembly Laboratory and Boston Geosyntec Corporation are working together to develop a new model of pipeline infrastructure. He pointed out that we can imagine the pipeline system in the future. The pipeline can expand or contract, change the volume or flow rate, and realize the peristaltic flow. The cost of pumps and valves is not expensive, can be fully pre-programmed, and the pipeline is adaptive.
The latest 4D printers do not guarantee the realization of self-assembly capabilities, but the self-assembly laboratory believes that this technology can bring about a technological revolution. The future areas include: biology, materials science, software, robotics, manufacturing, transportation, infrastructure, construction Industry, art and space exploration.
