Selective Laser Sintering
An Innovative Technology for SLS 3D Printing
Selective laser sintering (SLS) 3D printing is a professional additive manufacturing technology trusted by a broad variety of manufacturers for its ability to create functional and robust plastic parts.
How Does it 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.
What Are the Benefits of EOS Selective Laser Sintering?
Selective Laser Sintering is an ideal and outstanding method and is used for complex parts and very popular in the field of plastic 3D printing due to its various advantages. Unlike some other 3D printing technologies such as stereolithography (SLA) and fused deposition modeling (FDM), the SLS 3D printing process does not require support structures. This enables the production of very complex, almost impossible 3D printed patterns. Only powder and power are needed to produce parts, no binders or additives.
