Rapid 3D printing of miniature organs holds potential for synthetic tissues

Researchers have announced a new method of rapidly printing 3D tissue models that may advance the technology towards the development of 3D-printed organs, which could eventually help address donor organ shortages for transplant procedures. In a research article published in Advanced Healthcare Materials, co-lead authors Ruogang Zhao and Chi Zhou, along with their team at the University at Buffalo Department of Bioengineering (NY, USA), demonstrated their new technique. The basis of the technique, stereolithography, has been established for decades and involves focusing a UV laser on the surface of a vat filled with photosensitive prepolymer. Upon irradiation, the polymer becomes...
