Virtual designs into physical objects/Rapid prototyping machines

Rapid prototyping machines, sometimes called 3D printers, are now commonly used in the design and manufacturing industries for creating solid three dimensional objects straight from CAD models. Currently there are various limitations with these machines but in the near future the price will reduce rapidly, the number of different materials that can be used to make parts will multiply, the resolution will become steadily finer and the build-speed will increase. It is likely that these machines will soon be within the reach of ordinary people following a similar evolutionary path to computer printers. Mail order rapid prototyping services are already available. 35px-More_large.png
