3D 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 object is created.

Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. World is changing more rapidly than ever before, students can bring their imaginations into existence with the help of 3-D printing technology.

As far as this technology can be used in education, it is a matter of bringing objects out of the computer screen into the hands of students for inspection, analysis, and others process that can benefit for physical manipulation. In that way, 3-D printers may eventually be able to bridge the gap between the physical and the digital-use a screen to find that you need, than print it into existence.
