Abstract
Direct metal laser sintering (DMLS) is a powerful tool to produce titanium based biomaterials because the ease to convert 3D medical imaging data into solid objects with excellent mechanical and corrosion properties. \DMLS\ samples can be functionalized by anodizing, allowing the growth of titanium oxide layers of enhanced properties. In the present paper, a complete characterization of the microstructure, mechanical properties and particularly, the corrosion behavior has been carried out to assess their possible use as biomaterial. The results of the anodized scaffolds are very promising, showing a Young Modulus near to the cortical bone and a low corrosion rate, ensuring their suitability for medical applications.
