I publish a list of Active users and top psoters on Bitcointalk.org in the past 24 hours. Newbie http://loyce.club/active/Fahim2005[/url] was on top with 34 posts, and as expected, it's plagiarism. He even received Merit for this, please ban him!

The 3D printing process builds a three-dimensional object from a computer-aided design model, usually by successively adding material layer by layer, which is why it is also called additive manufacturing.3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
3D printing, also known as additive manufacturing, is the exact opposite of the traditional way of making objects. Instead of machining or "subtracting" material to form an object - much like how a sculptor cuts away clay - 3D printing adds layer upon layer of material to build an object. Product designers and engineers upload a digital (CAD) file to a 3D printer, which then prints a solid 3D object.
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.
3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.
