Shape-morphing systems, also known as 4D printing, add the dimension of time to 3D printing. Using smart materials that respond to external factors such as heat, light, moisture, electric current, or pressure, objects created through 4D printing can alter their shape or properties. Picture a fabric that seamlessly adapts its breathability according to humidity levels, or a plumbing network that flexes and contracts in sync with temperature changes. We reached out to experts in the additive manufacturing (AM) industry, including thought leaders, journalists, and enthusiasts, to explore the possible impact of shape-morphing systems on various industries. Here are their insights on the future direction of the market.
