On April 6, 2018, researchers at Dartmouth College have made great strides in developing new 3D prints. We have developed an innovative "smart ink" that changes the shape and color of an object over time in 3D. This process is often referred to as 4D printing, the next generation additive manufacturing method, and can be used in various applications in the biomedical and energy industries.
As Chen Fengke, an associate professor of chemistry at Dartmouth University, says: "Many 3D printing structures are just shapes that do not reflect the molecular nature of the material, but these inks bring functional molecules to the 3D printing world, and now they can print smart objects for various purposes. "
This groundbreaking project seeks to find more ways to control the molecular structure of 3D printed objects. The benefits of doing so are enormous, and design capabilities are greatly enhanced.
Inks are created based on polymer "carriers" that integrate smart molecular systems into printing gels. This allows their function to be macroscopically converted from nanoscale, no longer cures after 3D printing, and the material undergoes further chemical reactions, fixing the active molecular components together and inducing conversion . For example, fluorescence tracking devices can be used to change the color of an object in response to external stimuli such as light.
These 3D printed "4D" objects can be scaled repeatedly. This reduction can be used to reduce the size of 3D print objects by a factor of 100 and provide 10x resolution. In other words, with the Dartmouth team of inks, you can extend the capabilities of a regular printer to the level of more complex printers, and because the ink is preprogrammed, you can print at high resolution without changing the operation. Object ability
This allows us to replace the $ 100,000 printer with a $ 1,000 printer. This technology is scalable, adaptable, and significantly reduces costs. "
Despite the fact that there is still a long way to move to a fully featured smart 3D system that adapts to the environment and changes its configuration dynamically, there are certain potential uses for the development of this new smart ink There is. The manufacture of improved precision filters and storage devices is currently believed to benefit from the ability to control structural transitions after printing.
The team summarized the project and its future potentials and said, "We believe this new approach will enable the development of small molecule based 3D printing materials and greatly accelerate the development of smart materials and devices."
