The concept of personalized medicine tailored to individual patients has garnered considerable attention recently, particularly in exploring the potential of 3D printing technology within the pharmaceutical and healthcare industries. 3D printing involves the layer-by-layer creation of three-dimensional objects from digital designs. This review aim to provide an in-depth discussion focusing on 3D printing technology, its role in drug delivery systems, and its application in the pharmaceutical product development process. Commonly categorized by material layering methods, 3D printers typically fall into inkjet, extrusion, or laser-based systems. The review delves into these different types of 3D printers and their diverse applications in drug delivery across various sectors. Additionally, it encompasses a selection of recent research conducted in the pharmaceutical realm concerning 3D printing for drug delivery applications and challenges. Keywords: 3D printed formulation, Laser based printing, inkjet printing, extrusion-based printing
