AMBER Materials Science Center, Ireland, are working on bone grafts through 3D Printing, either via autografting or allografting by inserting the bioprinted materials and patient's stem cells subcutaneously and regenerating the bone. Funded by Science Foundation, Ireland and hosted at Trinity College, Dublin; this new method will provide less painful, successful and affordable reach to the patients with Cancerous tumors or suffering bone defects.
