Numerical Analysis of Additively Manufactured, Individual Titanium Implants Designed in a Virtual Environment

Open access

Abstract

The aim of this study is the design, manufacture, and development of a metallic rehabilitation device (titanium frame structure) that is created with a printing process. Product design is inspired by the Computed Tomography (CT) based reconstruction method, during which a metallic frame structure is designed that perfectly fits the retrieved bone surface. The internal structure of the designed metallic frames is a statically analysed three-dimensional construct which makes it possible to create individual product types. Constructs with different structure are checked by finite element analysis. Our goal is to establish a standardised manufacturing process, in which specific mechanical stressing can be carried out and optimal product type chosen, depending on different cases. At the end of this study, our solution of choice is demonstrated with surgical pictures.
