SLS (Selective Laser Sintering)
SLS is an industrial 3D printing procedure perfect for manufacturing end-use parts.
In SLS, laser selectively sinters polymer powder elements intertwining them and constructing a section layer-by-layer.
SLS produces useful plastic elements with isotropic mechanical attributes that could be used for end-use and low volume construction or detailed prototyping.
It may seem like SLM. Both the techniques are similar in essence, but technically different. The material used in SLM us melted rather than sintered. Also, SLS is a newer technology that mainly aims to make prototypes and low-volume production of component parts.
How does work SLS?
SLS is becoming popular in many industries due to its long list of advantages.
The sintered powder bed lets you produce many embedded patterns and complex geometries in the object. For example, SLS can help you in making conformal cooling channels.
Also, the complex parts can be built easily without altering the surface from support removal.
The components produced using SLS have an excellent stiffness and possess high strength.
SLS is a popular technology in many production industries. It can easily produce many complex technologies easily.
It is widely used in making automotive hardware and wide tunnel models. SLS is also used widely for making end-use parts in the aerospace industry, military, and electronics hardware as well as medical equipment.
SLS is also being used for producing tools for other procedures. It produces jigs and fixtures that make other traditional manufacturing processes easier.
SLS has also been used by some artists. However, it is not used at domestic levels because it uses laser and the equipment is expensive.
