Application of additive manufacturing in the biomedical field- A review

Abstract

Three dimensional (3D) bioprinting is a rapidly developing and emerging field in medicine and engineering. It allows for the production of three-dimensional structures that mimic body tissue function, which can be used in drug delivery and medical research such as cancer studies. In addition, bioprinting can provide patients with specific, controlled microstructures that mimic their natural geometries, increasing the rate of take-up with tissue implants and ongoing success. Towards that, a comprehensive review on the development of biomaterials, osseous tissues, bone and the vascular tissue bioprinting was conducted. These provide an insight into the latest research trends, difficulties, and understanding of the technologies used. Before implementation to replicate a human organ, there are variety of limitations to overcome together with the questions of ethics. Though bioprinting is still in its infancy period, it can play a vital role in tissue engineering in near future.
