Figuring out how to avoid the complications caused by 3D printed facial implants has become a crucial problem with 3D printing technology. The good news is that Professor Yoon Won-soo from Korea Polytechnic University seems to have found a solution. He and his team have developed a new biodegradable 3D printing material, whose 3D printed implants will not only greatly avoid any complications but could also accelerate the regeneration of natural tissue and gradually dissolve until they completely disappear.
