3 D PRINTING TECHNOLOGY IN PHARMACEUTICAL PRODUCT DESIGN

Three-dimensional (3D) printing, also called additive manufacturing, has become a major change in the pharmaceutical world. This technology allows for making drug products layer by layer using digital designs. It gives a high level of accuracy and flexibility when creating different types of dosages. Unlike traditional methods, 3D printing can make medicines that are tailored to each person's needs. These medicines can be customized in terms of how much medicine is in each dose, the shape of the pill, and how the drug is released over time. Different 3D printing methods, such as fused deposition modeling (FDM), stereolithography (SLA), inkjet printing, selective laser sintering (SLS), and pressure-assisted microsyringe (PAM), have been used to make complex drug forms. These include multi-drug pills, quick prototypes, and customized medicines that are especially helpful for children, elderly people, and those with special needs. Even though 3D printing has many benefits like high accuracy, less waste of materials, and better patient adherence, it still has some issues. These include limitations with the materials used, keeping drugs stable, getting approval from regulators, and making it work for large-scale production. The approval of Spritam® (levetiracetam) by the U.S. FDA in 2015 was a big step forward, showing that 3D-printed medicines can be practical. In the future, combining this technology with artificial intelligence, nanotechnology, and pharmacogenomics could lead to more personalized and on-site drug production. Overall, 3D printing is changing how drugs are designed, offering new and better ways to provide individualized, efficient, and innovative healthcare solutions.
