3-D Printing Spurs a Manufacturing Revolution (NYT)



A wealth of design software programs, from free applications to the more sophisticated offerings of companies including Alibre and Autodesk, allows a person to concoct a product at home, then send the design to a company like Shapeways, which will print it and mail it back.

Based on research done by Dr. Behrokh Khoshnevis, an engineering professor at the University of Southern California, Contour Crafting has created a giant 3-D printing device for building houses. The start-up company is seeking money to commercialize a machine capable of building an entire house in one go using a machine that fits on the back of a tractor-trailer.


The 3-D printing wave has caught the attention of some of the world’s biggest technology companies. Hewlett-Packard, the largest paper-printer maker, has started reselling 3-D printing machines made by Stratasys. And Google uses the CADspan software from LGM to help people using its SketchUp design software turn their creations into 3-D printable objects.
