The use of powder metallurgy to produce titanium based components of complex shapes is an attractive technique, especially for porous or 3D designed open structures. Foams and reticulated open networks may find application in both the biomedical and aerospace fields. They offer competitive structural and functional properties compared to the traditional materials used so far. In the biomedical field, the use of titanium or titanium alloy foams represent an important improvement in terms of mechanical safety and long term behaviour of the implant. In the aerospace field, high temperature creep resistance and light-weight components may solve the constant issue of combining good structural and functional properties such as in turbine components, spacers and fasteners. In the present work, the gelcasting foaming technique is used to produce porous structures and their main properties in terms of morphology and mechanical performance are presented.
