3D printing technology allows for the creation of customized, personalized doses and has applications in the pharmaceutical industry. 3D printing works by building up a three-dimensional object layer by layer from a digital file. It offers advantages over traditional manufacturing like lower costs, less waste, and reduced production time. The technology is being used to produce things like food, toys, medical devices, and drugs. One example is Spritam, the first FDA-approved 3D printed drug product.
