Three-dimensional (3D) printing of human tissues and organ has been an exciting research topic in the
past three decades. However, existing technological and biological challenges still require a significant
amount of research. The present review highlights these challenges and discusses their potential solu-tions such as mapping and converting a human organ onto a 3D virtual design, synchronizing the virtual design with the printing hardware. Moreover, the paper discusses in details recent advances in formu-lating bio-inks and challenges in tissue construction with or without scaffold. Next, the paper reviews fusion processes effecting vascular cells and tissues. Finally, the paper...
