3D printing offers a method to produce prototypes of objects that can be used to create production products or create objects for production use; one of its greatest advantages is removing the need for sophisticated engineering of parts.
3D printing employs numerous methods and more than 100 materials, but the basic premise is that layers of plastics, paper or metals are laid down on a hard platform or powder base. Computer-aided design (CAD) programs are used to manipulate images in preparation for printing.
Last week's Inside 3D Printing Conference and Expo in San Jose showcased the impressive advances happening with 3D printing, which is used for everything from constructing buildings to constructing lunch. Here are some of the interesting projects that were on display.
