Progress and challenges on extrusion based three dimensional (3D) printing of biomaterials
Additive manufacturing techniques have made strides in innovation over the past decades where it is now applicable and practicable in the biomedical field. Three dimensional (3D) bioprinting can construct biological tissue structures and it is possible in near future that bioprinting technique can make functional organs. In view of that, the present paper reviews the progress and challenges on the bioprinting of biomaterials. Towards that, a systematic review was conducted with chronological development in this fields together with preparation of biomaterials before actual printing and elaborate description on extrusion-based printing technology. There are variety of limitations to overcome before 3D bioprinting can successfully replicate a human organ. Bioprinting is still a relatively new engineering technique and can play a significant role in tissue engineering and regenerate medicine in near future.
