Additive manufacturing has proved to be one of the most disruptive innovations to modern industry. Whether used for prototyping or manufacturing, additive methods — especially 3D printing — have completely revolutionized the way manufacturers design, develop, and produce products and parts. The 3D printing process is used across a range of industrial sectors, including aerospace , automotive , medical, and even food and beverage. In recent years, though, researchers have developed ways to make this innovative technology even more sophisticated — by tapping into the fourth dimension. While the fourth dimension remains a mysterious, almost mystical concept that physicists, engineers, and mathematicians have theorized about for years, when dealing with additive manufacturing, it simply refers to the inclusion of the elements of time and motion in addition to the standard measurements of length, width, and depth. What does this mean exactly? Put simply, a 4D-printed object will transform itself […]
