Using under $ 1,500 worth of materials, scientists have built a 3 - D metal printer than can lay down thin layers of steel to form complex geometric objects. (sciencedaily.com)
This was then subjected to finite element analysis, an engineering technique that predicts stress and strain in a complex geometric object. (sciencedaily.com)
