Revolution in The Making: A Survey of Emerging Applications and Technologies In 3D Printing

The existing work reviews the latest advancements and applications of 3D printing in the pharmaceutical sphere, which have altered drug development technology towards personalized and controlled release profiles for dosing forms and effective demand production [1]. The current technology has the capability of evolving from a date of inception in 1996 to systems dependent on sheet lamination, liquid, powder, and extrusion. FDA approval opened the door to marketing mass production of drugs using 3D printing [2]. It paved the way for initiating 3D-printed medicine. There is also a lot of use for those interested in veterinary medicine, while providing unique dosage forms for animals with special dosage needs [3]. In recent years, patient-centric pharmaceutical design would make today-the use of 3D printing for producing personalized dosage forms likely, where drugs could be encouraged to improve adherence towards treatment [4]. The inclusion of Formulation by Design (3FD) also harmonizes tablets formulations on regulated release rates and kinetics [5]. All the benefits notwithstanding, it is impeded by material limitations, printer technology limitations, and regulatory issues, but the biggest is in terms of broader implementation [6]. However, even though it poses such challenges, this technology could still potentially change medicine, from personalized drugs to tissue engineering and surgical simulation. As 3D printing technology advances, they are yet to be redefined for future scope and possibilities in drug delivery, personalized medicine, and treatment of the patient [7].
