Review on 3D Printing Filaments Used in Fused Deposition Modeling Method for Dermatological Preparations.

Three-dimensional printing, particularly Fused Deposition Modeling (FDM), has revolutionized dermatological drug delivery by offering the ability to create personalized and precise drug formulations. This technology enables the design of customized drug delivery systems using a variety of polymers, such as Polylactic Acid (PLA), Polyvinyl Alcohol (PVA), Polyethylene Glycol (PEG), and Polycaprolactone (PCL), each with unique properties that enhance drug release, patient compliance, and treatment efficacy. This review analyzes these polymers in terms of their advantages, limitations, and suitability for dermatological applications. The ability to tailor these materials offers significant potential in overcoming treatment regimens. Additionally, the customization of three-dimensional-printed drug delivery systems provides a platform for creating patient-specific solutions that are more effective and adaptable to individual needs. Despite challenges such as moisture sensitivity and mechanical brittleness, the potential of FDM technology to improve dermatological treatments remains promising. The future of three-dimensional printing in dermatology lies in the integration of optimized materials and advanced printing techniques, which could further enhance patient-specific care and broaden the clinical applicability of these technologies in the pharmaceutical and biomedical sectors. By addressing these limitations and expanding material choices, FDM-based drug delivery systems have the potential to revolutionize the management of dermatological conditions, offering improved therapeutic outcomes and quality of life for patients.
