SLS

Definition

Selective Laser Sintering (SLS) is a 3D printing technology that uses a laser to fuse powdered materials, typically plastics, metals, or ceramics, into solid structures. This process allows for complex geometries and the production of functional parts, making it a key technique in both manufacturing and medical applications, particularly in the assembly of parts and dental solutions.

5 Must Know Facts For Your Next Test

1. SLS can produce parts with intricate designs and internal structures that would be impossible with traditional manufacturing methods.
2. The materials used in SLS are often thermoplastics, allowing for durability and heat resistance in the final product.
3. Parts created through SLS can often be used directly in functional applications, such as in aerospace or automotive industries.
4. SLS technology enables the production of customized dental devices, like crowns and bridges, that fit individual patients more accurately.
5. One of the significant advantages of SLS is that it does not require support structures, as the un-sintered powder surrounding the part provides necessary support during the printing process.
