Fused deposition modelling (FDM) is a material extrusion process that utilises thermoplastic polymers to construct objects in an additive manner. This singular platform offers new prospects for the fields of engineering and medicine, making it a widely applicable 3D printing technology. As such, FDM has multitude applications ranging from prototyping and consumer products to industrial processing. Known for its low cost, diversity, portability and simplicity, this technology has the potential to revolutionise the field of medicine by providing means to introduce innovative concepts, including dual printing and contemporaneous forms of drug delivery systems. Its ability to precisely design and fabricate novel structures allows more control over drug performance, enhancing the quality of treatment and avoiding constraints often imposed by conventional manufacturing processes. This chapter overviews the current industrial advancements of the FDM technology in engineering and medicine, discussing the potential advantages of implementing this technique in pharmaceutical production and providing an insight on its current limitations.
