Impact energy absorbing system for space lander is an important technology for space exploring missions. Open-cell porous aluminum manufactured through 3D selective laser melting process has been used on the energy absorbing system. Compression tests for cylindrical and hemispherical shaped porous aluminum with different porosities revealed the high potential as an energy absorbing component. It was found that the suitable heat treatment were effective to increase the energy absorbing potential of the porous aluminum.
