New technique can print life-like organ models in minutes

 .

Conventional 3D printing involves the meticulous addition of material to the 3D model with a small needle that produces fine detail but is extremely slow –taking six or seven hours to print a model of a human part, such as a hand, for instance. The lengthy process causes cellular stress and injury inhibiting the ability to seed the tissues with live, functioning cells. The method developed by the SUNY Buffalo group, led by Rougang Zhao, PhD, Associate Professor of Biomedical Engineering in the Jacobs School of Medicine & Biomedical Sciences, takes a different approach that minimizes damage to live cells. The rapid, cell friendly technique is a significant step towards creating printed tissues infused with large numbers of living cells. Instead of a needle moving across a surface slowly building the details of the 3D model, Zhao and his team members have developed a system […]
