Ceramics are moving into the 4D printing realm for the first time
For some materials, researchers have already moved beyond 3D printing to what’s being called 4D printing. In this process, time becomes the fourth dimension and objects can transform themselves over time when influenced by elements such as heat, mechanical force, or a magnetic field.
Now, scientists in China have developed a novel ink that takes ceramics into this 4D printing realm for the first time, paving the way for new structural applications of the material—including for electronic devices and aerospace. Specifically, a team at City University of Hong Kong created a ceramic ink using a mixture of polymers and ceramic nanoparticles that can print ceramic precursors that are soft and can be stretched three times beyond their initial length.
