Pedro Munoz helpfully raises the "strength" aspect of 3D-printed products. Because the products are created in a layered manner, a product's mechanical properties are likely to be anisotropic, that is, different along different along different axes.​ ------------------------------ Stu Walesh ...

Neil Kazen is correct about Henry Ford's contributions. I was too casual with my language. Ford and his personnel created the mass production system which greatly reduced the cost of cars and, as a result, greatly expanded car ownership. As an aside, in the very early 1900's, Henry Ford's personnel ...

Thank you for highlighting 3D printing. I've been tracking large-scale 3D printing mostly of civil engineering types of structures and structure components. It's in it infancy and so different than traditional on-site and precast construction that it will initially be ignored, discredited, and opposed. ...

Thomas Halmi: Thank you for sharing information about military use of large scale 3D printing. You caused me to think further about the following: 1) Our military values speed in construction both in combat and in providing post-natural disaster aid. 3D printing has the potential to do that. ...

I serve, as one of a group of advisers, for a confidential project with a short-term goal of 3D printing, as a demonstration, another concrete house in the U.S. Based on what I have learned so far (two months), large-scale 3D printing could explode within civil engineering in the next few years, although ...
