Perfection with 14 Sides
Weight reductions can be accomplished by using titanium and other lightweight materials which are easier to print than machine. It can also be accomplished by replacing solid structures with partially hollow structures. The key is removing as much material as possible without compromising the strength of the part.
To create the internal shape of a strong, lightweight part, a truncated octahedron may be the world's most perfect shape. A fourteen sided polyhedron composed of six square faces and eight hexagonal faces, a truncated octahedron has edges which are all the same length. A truncated octahedron can be created by joining two square pyramids at their based then cutting off all six of the corners to remove one third of the edge length.
What is your favorite shape?
