What is 3D printing?
3D Printing is a process of making 3 dimensional solid objects from a digital file. It is also known as additive manufacturing.
First of all, 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. Hence each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
It is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
Above all, it enables you to produce complex (functional) shapes using less material than traditional manufacturing methods.

How Does It Work?
Certainly, It all starts with the creation of a 3D model on your computer. This digital design is, for instance, a CAD (Computer Aided Design) file. While a 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner. With a 3D scanner, you’re able to create a digital copy of an object.
Future Of This Printing
Even more, It is predicted by some additive manufacturing advocates that this technological development will change the nature of commerce. Because end users will be able to do much of their own manufacturing. Rather than engaging in trade to buy products from other people and corporations.
Furthermore, 3D printers capable of outputting in colour and multiple materials already exist. They will continue to improve to a point where functional (electronic) products will be able to be output, with effects on energy use, waste reduction, customization, product availability, medicine, art, construction, and sciences. Hence, this printing will change the manufacturing world as we know it.
