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.
Discover what makes SLS technology so powerful and find out more about the SLS 3D printing process and our systems. EOS has captured more than 30 years of experience in industrial 3D printing and offers a wide range of polymer 3D printers and materials.
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.
