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.
