How 3D Printing Works

makerbot 3D-printing-exhibition-designboom-093D printing or additive manufacturing is a process of  making three dimensional solid objects from a digital  file.  The creation of a 3D printed object is achieved  using  additive processes. In an additive process an  object is  created by laying down successive layers of  material until the entire object is created. Each of  these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object).
