Among additive manufacturing approaches, fused deposition modeling (FDM) is among the most promising techniques due to its flexibility, cost-effectiveness, and potential for personalized drug delivery. This review discusses the fundamental principles, commonly used materials, and recent technological advancements in FDM-based production of oral pharmaceutical dosage forms. Central to this discussion is FDM's ability to tailor drug release, enabling immediate, controlled, and delayed profiles by manipulating formulation composition and printing parameters. We critically evaluate polymer selection, formulation strategies, and process variables that govern release kinetics. Potential advantages, including patient-specific dosing, improved drug stability, and cost-effectiveness, are discussed alongside persistent challenges related to regulatory approval and manufacturing scalability. By synthesizing current evidence, this review aims to clarify the role of FDM-based 3D printing in advancing personalized oral dosage forms.                 Peer Review History: Received 8April 2026;   Reviewed 13 May 2026; Accepted  11 June; Available online 15 July 2026 Academic Editor: Dr. Ahmad Najib, Universitas Muslim Indonesia,  Indonesia, ahmad.najib@umi.ac.id Reviewers: Mrinal Kanti Bhoumik, Jubilant Cadista Pharmaceutical Inc., mrinal_bhoumik@yahoo.com  Dr. Nada Farrag, Misr International University, Egypt, Nada_Hazem87@hotmail.com 07 15 2026 http://creativecommons.org/licenses/by-nc/4.0 10.22270/ujpr.v11i3.1581 https://ujpronline.com/index.php/journal/article/view/1581 https://ujpronline.com/index.php/journal/article/download/1581/2191 https://ujpronline.com/index.php/journal/article/download/1581/2191 https://ujpronline.com/index.php/journal/article/download/1581/2192 https://ujpronline.com/index.php/journal/article/download/1581/2216
