A Review Article on Fused Filament Fabrication- 3D Printer, a Boon to the Pharmaceutical Field for Delivering Therapeutic Dosage Forms.

3D printing technology has drawn interest from the pharmaceutical and medical device industries due to its various applications in the healthcare sector across several platforms. 3D printing is a sustainable technology for industrial applications because of its many benefits, including little debris, simplicity of manufacturing, decreased human participation, minimal energy efficiency, and post-processing. This paper outlines numerous 3D printing processes, the current innovative research involving the topic of fused filament fabrication in 3D printers, the different methods for loading drugs into filament, the 3D-printed drug delivery systems, quality considerations, technology implementation challenges in control of fused deposition modelling (FDM) or fused filament fabrication (FFF), risks to operators and regulatory guidelines for 3D-printed products in the pharmaceutical field.
