Selective Laser Sintering

Laser sintering is a popular and versatile 3D printing technology thanks to its high precision, design freedom, and wide range of production-grade materials. Suitable for all stages of the production lifecycle, from prototyping to small series or custom manufacturing, laser-sintered parts need no support structures, making it possible to produce even the most complex geometries.

Selective Laser Sintering (SLS)

Selective laser sintering (SLS) is a powerful 3D printing technology that produces highly precise and durable components capable of being utilized straight in end-use, low-volume manufacturing, or rapid prototyping. SLS can construct components wholesale without support structure needs. SLS products are largely nylon and An additive manufacturing layer technology, selective laser sintering includes making use of a high-power laser (for instance, a carbon dioxide laser) to fuse little particles of plastic powders right into a mass that has a desired three-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or check information) on the surface of a powder bed. After each cross-section is checked, the powder bed is decreased by one layer thickness, a brand-new layer of material is applied on top, and also the selective laser sintering procedure is repeated till the part is finished.

How Does Selective Laser Sintering (SLS) 3D Printing Work?

The EOS SLS 3D printer uses a laser to melt polymer powder and fuse it into a solid 3D printed part. SLS is part of the Laser Powder Bed Fusion (LPBF), one of the most advanced and reliable technologies in 3D printing.

Using a CAD design model, the laser melts the plastic material precisely at the predefined points in the powder bed. The technique requires no support structures, as the unfused powder supports the part during printing. After completion of the melting process, a new layer of powder is applied. This process repeats layer by layer until the part is completed.

SLS is a new high end method that has been primarily used for rapid prototyping and small batch production of components. Within the process of commercialization of selective laser sintering, the production tasks are being expanded enabling new design options for a wide range of products.

Why Use SLS?

See how SLS uses actual thermoplastic and elastomeric materials to produce parts with good mechanical properties. Final parts can be used to test future injection molding designs or as functional, end-use components.
