Printing 3D object
Printer is now become the need of people. Many people use it for their own purposes such as printing some documents, photos, or even used by large-scale publisher to print their books. The common printer usually produce a 2 dimensional object just like written text in a paper. Now, because of the rapid-growing technology, people can print a 3 dimensional object. I know it’s lill’ bit weird, but that’s the fact. Using 3D printer can make that thing happened in the real life.
“Three-dimensional printing makes it as cheap to create single items as it is to produce thousands and thus undermines economies of scale. It may have as profound an impact on the world as the coming of the factory did....Just as nobody could have predicted the impact of the steam engine in 1750—or the printing press in 1450, or the transistor in 1950—it is impossible to foresee the long-term impact of 3D printing. But the technology is coming, and it is likely to disrupt every field it touches”.
—The Economist, in a February 10, 2011 leader
A 3D printer works by taking a 3D computer file and using and making a series of cross-sectional slices. Each slice is then printed one on top of the other to create the 3D object. One method of 3D printing consists of an inkjet printing system. The printer creates the model one layer at a time by spreading a layer of powder (plaster, or resins) and inkjet printing a binder in the cross-section of the part. The process is repeated until every layer is printed. This technology is the only one that allows for the printing of full color prototypes. This method also allows overhangs. It is also recognized as the fastest method. src
There have been several, often related efforts to develop 3D printers suitable for desktop use, and to make this technology available at price points affordable to many individual end-users. Much of this work was driven by and targeted on DIY/enthusiast/early adopter communities, with links to both the academic and hacker communities. src RepRap is a project that aims to produce a FOSS 3D printer, whose full specifications are released under the GNU General Public License, and which can print a copy of itself. As of November 2010, the RepRap can only print plastic parts. Research is under way to let the device print circuit boards too, as well as metal parts. src
