The 3D printing technology comes into the fight in 1986, but has won only in 1990. In recent years, 3D printers are available in the market at low costs, but the performance levels are set high standards.
The technology is under rapid prototyping systems and includes a fully functional ink jet printing as well. The technology of 3D printing is preferable because it promotes full color prototypes.
The 3D object is created layer-wise, one after the other places a fine on another. A fine powder, consisting of plaster, corn starch and resins are used to build the layers. These layers are bonded by an adhesive to the inkjet printhead. The shape of each cross section of the desired object is determined by a CAD file. The force of these impressions may be increased, thermo-set polymer impregnation or wax.
Some printers use a liquid photopolymer for the formation of the layers mentioned. The photopolymer layer is a cure with a UV lamp (UV), is connected to the inkjet printer.
There is also a method called Fused Deposition Modeling (FDM), in which a nozzle deposits of molten polymer into a mold layer by layer. The strength of these objects can be increased by inserting a metal one.
The crossing of the finish cutting of thin layers allows an exact form of laminate. Each technology has its own advantages and disadvantages. However, consider the most important factors are the speed of the surface, the cost of the printer object and the materials used (powder or polymer) and the capabilities of color among others.
Some applications of 3D printers include architectural design, print organs, primary metal smelting, education and others.
