Illustration of the 3D printing process from brainstorming to computer-aided design modeling and fabrication of various parts that have been created to fight against the COVID-19 pandemic. The typical devices developed and used in the early days of the pandemic include: hands-free handle, face masks, ventilators, face shields and swabs. Indeed, the possibility of personalizing and adapting pharmacological therapies to the individual needs of each patient through 3D printing technologies is an indisputable advantage, which will have a huge impact on the development of personalized medicine [122,123]. However, as to 3D bioprinting of whole organs, the technology is still in its Use of 4D Printing in Healthcare. 4D printing has the potential to support a wide range of medical applications, including: Tissue and organ fabrication; Creation of customized prosthetics, implants and anatomical models; Pharmaceutical research. The advent of 3D printing brought many changes to the healthcare sector. teHvV.
