Abstract
The anatomy of each patient is unique. This statement explains the growing demand for personalized treatments and, therefore, the supply of services and customized products within the medical devices area. The main demands are in orthopedic, craniofacial, endovascular implants, surgical guides and surgical instruments. These devices are designed according to the patient's anatomy and the procedure selected by the health team for treatment. In such cases, medical images, such as, CT and MRI are utilized to obtain a geometric three-dimensional virtual model of the patient's region of interest. From this model, in a virtual environment, the implants and guides are designed and the surgical planning is performed by a health team. After that, the devices are manufactured, sterilized and taken to the surgical procedure. This work aims to reduce the gap between design and manufacturing of custom implants made by selective laser melting (SLM) using Ti6Al4V. It is intended to present the initial results of the development of a method within the Design for Additive Manufacturing focusing on custom metal implants. This new method will take into account how microstructure and dimensional tolerances influence the manufacturing process. It should also explore the ability of SLM process to build complex and porous geometries. These issues are important for the restoration of bone function and to promote the mechanism of osseointegration.
