4D printing is an advanced form of 3D printing that incorporates time as a fourth dimension, allowing printed materials to change their shape or properties over time in response to environmental stimuli. This process often involves smart materials that can react to changes in temperature, humidity, or other factors, enabling dynamic transformations. It connects closely with soft robotics, where adaptable structures can improve functionality and interact more effectively with their environments.
congrats on reading the definition of 4D Printing. now let's actually learn it.
