3D printing for functional tissue engineering

Three-dimensional printing (3DP) or additive manufacturing (AM) has critical potential as a manufacturing strategy in fabricating functional scaffolds for tissue engineering and regenerative medicine. The 3DP has the capacity to create complex parts (scaffolds or tissue or organ) with the use of different biomaterials. This chapter will address the current 3D powder- and paste-based innovations utilized in tissue development and study the vivid biomaterials that are being researched. There are few prerequisites that should be tended to recreate the functional tissue, such as mechanical strength, porosity, cell aggregation, cell composition, and cell proliferation. This section of the book presents a cutting-edge investigation report of 3DP innovations for tissue engineering applications and the immediate 3DP developments of practically evaluated scaffolds. Innovative constraints will also be about to feature the chance of future upgrades for new 3DP strategies for tissue engineering. The ultimate aim of this review is to sum up the advances in 3DP of some kinds of tissues and present the most innovative bioinks to contemplate and examine the preferences and impediments of AM when utilized for printing a scaffold, tissue, and organ.
