Selective Laser Sintering (SLS) is a versatile 3D printing technology, often used for functional prototyping, small-batch production and end-use parts. SLS parts can be found in airplanes, wearables, machine components, production tools and more.

With SLS, a laser fuses together polymer powder particles, building a part layer by layer. This print method is best for producing high-accuracy functional prototypes and parts with complex geometries. Since the powder supports the part as it’s printed, no additional supports are needed.

With High Speed Sintering (HSS), a thin layer of loose powder is applied to a building platform. An inkjet print head moves over the entire surface of the platform, depositing an infrared-absorbing fluid directly onto the powder where sintering is desired. The build area is then illuminated with infrared light, fusing the powder under the fluid into a layer.
