Selective Laser Sintering
Selective laser sintering (SLS) is an industrial 3D printing process that produces accurate - rapid prototypes and functional production parts in as fast as 1 day. Multiple nylon-based materials are available, which create highly durable final parts.
SLS design guidelines will help you understand capabilities and limitations.
Why Choose Selective Laser Sintering For Your 3D Printing Project?
SLS is ideal to make functional parts that have greater toughness and higher impact strength than parts produced through stereolithography (SL). SLS lacks the surface finish and fine feature details available with SL. We offer a number of secondary services to further enhance your 3D-printed project design or finish. These services are available when ordering a part manufactured by Protolabs.
SLS material data sheets can be found in our Material Comparison Guide
How Does Selective Laser Sintering Work?
The SLS machine begins sintering each layer of part geometry into a heated bed of nylon-based powder. After each layer is fused, a roller moves across the bed to distribute the next layer of powder. The process is repeated layer by layer until the build is complete.
When the build finishes, the entire powder bed with the encapsulated parts is moved into a breakout station, where it is raised up, and parts are broken out of the bed. An initial brushing is manually administered to remove a majority of loose powder. Parts are then bead blasted to remove any of the remaining residual powder before ultimately reaching the finishing department.
