Advancing Cranial Implants with Incremental Forming of Titanium Grade 2: A Biomedical Application

Titanium, distinguished for its exceptional strength-to-weight ratio, was once overlooked due to its high cost and challenging formability. Recent projects have embraced titanium as a substitute material in specific components within the aerospace and mining sectors. The biomedical industry has also warmly embraced titanium owing to its resistance to decomposition and remarkable compatibility using the human body. Incremental sheet forming represents a forming technique capable of shaping intricate and asymmetrical components by inducing highly localized deformations. In the ISF process, the component takes shape through a combination of stretching and bending while preserving the material's crystal structure. This technique can be executed with any 3-axis Computer Numerical Controlled machine, rendering it readily accessible and cost-effective for the manufacturing sector. This research paper delves into the application of incremental forming technology for the creation of biomedical titanium plate implants tailored for minimally invasive surgical procedures. It proposes a customizable development chain capable of creating patient-specific biomedical implants, thereby harnessing the potential of incremental forming technology in the health-care domain.
