3D cell printing technology opens a new chapter of bio medicine

Prof. Dong-Woo Cho of Department of Mechanical Engineering of Pohang University of Science and Technology

Realizing customized medical services with 3D printing technology

3D printing technology has rapidly developed in recent years. High precision printers are being introduced at the moment and its cutting edge technologies enabled us to apply its advantages to bio medicine. For example, if the existing 3D printing technology could scan the damaged skeleton to make an artificial one, Prof Jo Dong-woo of Intelligence Production System Research Institute of Pohang University of Science and Technology is working on directly planting the cell in the 3D printed product to restore the damaged part as it was. Jo and his team launched 'Rapid Moulding-based Organs/Tissues Printing Researcher Team' in 2010, developed 'direct printing technology in 3 dimensional structure production, and tried to make artificial organs. Jo says "3D printing technology can enable us to control the external shape and inner structure of the organs in our body. To make it realized, we are working on developing 'organ restoration artificial supporter' by using body-friendly high molecule with which we will create even living cells through 3D printing technology." The researchers of the institute are majored in various subjects such as machine engineering, life science and body materials and they are carrying out researches in cooperation with clinicians of various hospitals. They developed 3D printers customized for medical use and a structure that can restore dented chick bones in 2014 with which they successfully implanted it to a patient.

Pushing forward the development of real organ-like artificial organs

Jo says "The development of a variety of safe and body-friendly materials is a must to realize 3D printing technology in the bio medical industry. Our researches and developments have already created a possibility to realize this, and we will make a great success if we keep pushing forward the development of real organ-like artificial organs. We might be able to make skeleton supporter, cartilage, liver, heart and eyes... you name it in the near future." For this, the researchers of the institute are working night and day on 3D cell printing and the optimized bio ink for the printer. The research team published a report on Nature Communications that the use of the bio ink extracted from heart, fat and cartilaginous tissue have been divided into each organ and it promoted its growth. The team is also working on developing 'Organ-on-a-Chip' that can imitate metabolism and immune systems, and the 'structure' that can deliver drug to a specific part of our body, and 'esophageal stents'. Power Korea wishes Jo and his team a great success in 2016.
