3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production, article.
This is so excellent. I keep hearing about new things that 3D printing can do better. One example is that areas which has to be made in many parts with traditional methods, can be printed in one part with 3D printing, making it cheaper, lighter, and stronger.
Another is that you can print in strengthening structures (ribs and such) directly in the material.
