Abstract
Three-dimensional 3D printing is a trending technology that makes complex 3D bodies by settling materials layer by layer. 3D printing uses different materials. And to make this technique sustainable, research has been going on. FDM is one of the special 3d printing techniques that are more affordable than other techniques due to its ease of availability and affordability. FDM 3D printing is based on the melt extrusion of thermoplastic polymers for the creation of objects. It is an emerging technique for creating customized and complex dosage forms tailored to the needs of the patient. This customizability makes FDM a powerful method for fabricating personalized and patient-tailored dosage forms. Therefore, in the last few years research has increased in demonstrating the utilization of FDM to produce solid dosage forms. There are many research articles published in the last 7 years. This review gives a basic overview of FDM and several stages involved in FDM 3D printing, filament preparation from hot-melt extrusion, and various new applications.
