Selective Laser Sintering is a method of designing objects through rapid manufacturing technique. A powerful laser like CD Laser is used with metal or plastic to make 3D objects. A 3D object is designed in the computer with the help of CAD design and then laser fuse the powdered and scan the cross sections of the design and convert it into the physical form layer by layer.

As compared to other prototyping methods, SLS method have wide range of materials to make the objects like polymers, nylon, polyester, stainless-steel, titanium and green sand. Basically, there are three different ways to build an object; partial melting, liquid phase and sintering. Depending upon the material, through SLS you can get the 100% real properties of the object as you desired.

The matches used in SLS are called SLS System, the very common and trusted machine in SLS production is Sinterstation SLS System. This method of prototyping is widely used in the market because of its speed and the ability to make complex designed with in short span of time.

SLS prototyping was firstly introduced by Dr. Carl Deckard professor in the Texas University during the 80s. This project is sponsored by DARPA, before this in 1979 a very similar process was made but it was not introduced in the market. Unlike the other prototyping methods, this method is fast, reliable and gives 100% results to make the new objects.
