Believe it or not 3d printers are a reality. You can easily print a 3 dimensional object from your pc. To understand how these work imagine you are using an ink jet printer, if you have ever watched the process you would see that a print head moves back and forth laying down a layer of ink. In 3 dimensional printing you have a very similar process except you are laying down very thin layers of resin from bottom to top to create the object. Another means of production is through the use of lasers. The image is traced out by lasers in a block of gel that is subsequently cured to a solid. this allows for complex features such as moving or interlocked parts. Imagine the benefits that may be realized from this technology. From being able to quickly design prototypes, visualize architectural structures, or even manufacture spare parts for your children’s toys. Looking in to the future there are efforts underway to use this technology for possible use in tissue engineering where organs are built by layering living cells. These printers can be used not only for commercial applications but home versions are available. Pricing for these printers ranges from 1200.00 to as much as 200000.00 dollars.
