When 3D printing meets smart materials, white carbon black opens up a revolution in the "fourth dimension". The photoresponsive white carbon black composite ink developed by XX laboratory can undergo volume expansion or contraction under specific wavelength light, achieving dynamic deformation of the printing structure. For example, the printed solar bracket can automatically adjust its tilt according to the sunlight angle, improving power generation efficiency by 12%; Medical stents can self degrade after releasing drugs in the body, avoiding secondary surgery. This technology has broken through the bottleneck of centimeter level accuracy and will be first applied in the fields of smart wearable devices and building structure monitoring by 2025. White carbon black is evolving from a static filler to a "living" material.
