What is 3D printing?
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 entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object
How does 3D printing work?
t 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) or with the use of a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object.
3d scanners use different technologies to generate a 3d model such as time-of-flight, structured / modulated light, volumetric scanning and many more.
Recently, many IT companies like Microsoft and Google enabled their hardware to perform 3d scanning, a great example is Microsoft’s Kinect. This is a clear sign that future hand-held devices like smartphones will have integrated 3d scanners. Digitizing real objects into 3d models will become as easy as taking a picture. Prices of 3d scanners range from very expensive professional industrial devices to 30 USD DIY devices anyone can make at home.

Services
Not everybody can afford or is willing to buy their own 3D printer. Does this mean you cannot enjoy the possibilities of 3D printing? No, not to worry. There are 3D printing service bureaus like Etba3ly 3D, Shapeways, Ponoko and Sculpteo that can very inexpensively print and deliver an object from a digital file that you simply upload to their website. You can even sell your 3D designs on their website and make a little money out of it!
There are also companies who offer their services business-to-business. When, for instance, you have an architecture practice and you need to build model scales, it is very time consuming doing this the old fashioned way. There are services where you can send your digital model to and they print the building on scale for you to use in client presentations. These kind of services can already be found in a lot of different industries like dental, medical, entertainment and art.
