Inside 3D printing
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.
