Complicated biological structures, such as tissues and organs, may be printed out of digital designs using the additive manufacturing process of 3D printing. As a result of the success of Spritam®, the first 3D medicinal product approved by the FDA, a large number of researchers have been interested in the topic, and work is currently underway to produce a wide range of individualized dose forms. The aim of this overview is to familiarize readers with 3D printing, its background, advantages, and obstacles, and the numerous manufacturing techniques utilized to create pharmaceutical goods. The benefits and relevance of 3D-printed, patient-specific dose forms are evaluated as well. The necessity of tailored dosing and the utilization of anatomical models, tissue and organ fabrication, and other 3D printing applications in the treatment of diseases like cancer, diabetes, cardiovascular problems, and neurodegenerative disorders are highlighted. There is a wide range of discussions regarding the potential disruptions in healthcare and manufacturing that 3D printing may cause as well as the regulatory issues that may arise as a result. This analysis of 3D printing technology has discussed its current and future manufacturing and medicinal applications, both of which hold great promise for improving the quality of life for humans.
