Researchers from the City University of Hong Kong (CityU) have successfully developed the world's first-ever 4D printing for ceramics that can be used to create complex, shape-changing objects.
4D printing is conventional 3D printing combined with the additional element of time as the fourth dimension.
Researchers also have developed a novel 'ceramic ink', which is a mixture of polymers and ceramic nanoparticles.
The printed ceramic precursors can be used in the manufacture of electronic devices.
Ceramic materials have much better performance in transmitting electromagnetic signals than metallic materials.
