The development of the latest 3D bioprinting medical applications depends to a large extent on how researchers overcome a large number of practical obstacles. For example, how do you let cells grow in 3D printed matter? How to ensure that 3D printed implants do not cause complications? Recently, the research team from the Korea Polytechnic University found a solution to the second problem mentioned above. Its latest biodegradable materials can be used in 3D printed facial implants and can promote tissue regeneration after implantation, while the original 3D printed structure will be slowly decomposed and absorbed by the body within a few years.
Not long ago, the Ministry of Science, Technology, ICT and Future Planning of Korea announced the results of this research. It is reported that the research project team is led by Professor Yoon Won-soo, who has been working on the use of biomaterial 3D printed implants and the use of soluble materials to promote tissue regeneration. Earlier this year, the same research team developed a biodegradable grid for facial bone surgery and has been approved by the Korean Department of Food and Drug Safety (MFDS).

It is known that in the current medical field, tissue regeneration, implant compatibility and implant manufacturing have been a major challenge. To date, patients with damaged facial bones must remove a bone from other parts of their body, then make an implant, insert the facial structure, and sometimes use a certain support structure.
Now, if you use this degradable biomaterial developed by the research team, you can create a perfect prosthesis without extracting the bone. And this material is also easier to insert, so the average surgery time is expected to be shortened to two hours (instead of the current eight hours). It is also the first 3D printed medical material developed in Korea. “Future research and clinical trial development projects for bone remodeling treatment will greatly benefit from this innovation,†said the research team leader.
