In selective laser sintering (commonly known as “SLS” or “LS”), 3D parts are created by fusing (“sintering”) powdered materials with an infrared laser beam. The result is strong, durable, and machinable parts with thermoplastic material properties similar to those of injection molded prototypes.
Our Selective Laser Sintering Work
Selective Laser Sintering (SLS) creates extremely durable prototypes
SLS results in parts featuring durability, but also detail
Utilize this technology to produce tough prototypes for functional testing
SLS can create parts that withstand real-world testing
SLS-printed parts can be painted or dyed during finishing
About Selective Laser Sintering
The use of SLS 3D printing (commonly called SLS prototyping or 3D SLS prototyping) is ideal for product prototypes that require exceptional strength or must closely approximate the properties of thermoplastics.
In SLS, three-dimensional parts are created by fusing (“sintering”) powdered thermoplastic materials such as nylon and elastomers with the heat from an infrared laser beam. Thin powder layers are repeatedly laser sintered, creating the desired 3D piece based on a 3D CAD model.
Selective Laser Sintering in Action
SLS vs. SLA
There are several key differences between parts created using SLS and parts created with stereolithography (SLA). These include:
SLS parts and prototypes are generally stronger and more durable than SLA parts.
SLS allows product prototypes to be created with material properties similar to those of injection molded prototypes.
SLS parts have a slightly grainy finish, unlike SLA prototypes, which are smoother.
It is easier to machine parts created using SLS than those created using SLA.
SLS allows for product prototypes in many different thermoplastic materials.
There is typically very little (if any) processing required after the SLS process is completed.
