3D printing is the latest engineering technology that is used to create 3D physical objects to be used in different projects. With the term 3D printing, layman people started thinking about a 3D design made on a paper or in a computer software just like 3D gaming. But actually this term is entirely different because in this technology a printer actually creates a physical three dimensional object with different layers and you can hold that object in your hand just like any object at your house.
When engineers have to make a new object they must have to read about the details of that object in depth which is not possible in 2D designs or even in a 3D design in a software. Three dimensional printing make it easy because it allows the manufacturer to read indepth details of a particular object when it is created by a 3D printer. A computer aided design CAD is created first which then converted into STL (Standard Tessellation Language) file. STL file is then converted into triangulated vertices which is then finally converted into thousands of 2D layers for that object. These 2D layers are then used to create a physical object which is three dimensional real object.
There are so many 3D printers available in the market, as this is a new technology so these printers are very expensive. If you want to buy a low price printer than you need to compromise on quality as only low quality Chinese printers were available. But now Chinese well reputed brand Wanhao has introduced its SLA printer in the market in very reasonable price.
Wanhao Duplicator 7 is one example of that excellent 3D printer that works on SLA technology. It has a resolution of 2560 x 1440 pixels for detailed printing on its HD LCD screen. For connectivity Wanhao Duplicator 7 has and HDMI input and a layer resolution of 35 micron. You can read complete specification of Wanhao Duplicator 7 3D SLA printer here:
