Custom Online 3D Printing Service and Selective Laser Sintering (SLS) Prototype
What is SLS?
The Basics Of Selective Laser Sintering
Selective laser sintering (SLS) is a powder bed 3D printing technology that produces highly accurate and durable parts capable of being used directly in end-use, low-volume production. SLS is a newer 3D printing process that is often thought of as a cousin to the popular metal 3D printing technology direct metal laser sintering (DMLS). Both processes work by utilizing a laser to precisely fuse a bed of powder to construct a part from a 3D CAD file. SLS specializes in nylon or polyamide powder particles to create parts, while DMLS uses metal particles, and is extremely common for prototyping and low volume production.
Concept Models | The speed and versatility of SLS printing lets product developers create physical snapshots of their designs through the iterative process.
|
Rapid Prototyping | SLS prototyping can be used to create fully-functional prototypes, complete with moving parts, as well as all-in-one assemblies.
|
Digital Manufacturing | The high accuracy and consistency of SLS makes it an ideal way to build large quantities of discrete or customized parts. |
Benefits of SLS 3D Printing
It can be used to make parts using a variety of SLS materials,
including plastic, metal, ceramic, or glass powder, making it a
popular machining process. Since SLS doesn’t require a support
structure like most other 3D printing tech, parts can be made in
greater quantities, but with less labor and material expense.
Additionally, because the support structure doesn’t need to be
removed, there is less risk of damage to the complex internal
geometries 3D manufacturing is capable of producing.
