Selective laser sintering (SLS) is a professional additive manufacturing technology for plastics 3D printing. With a SLS 3D printer, you can create plastic parts based on CAD Data (Computer Aided Design Data). With more than 30 years of experience in industrial 3d printing, EOS has perfected the method of selective laser sintering and offers a wide range of plastic 3D printers and materials.
The SLS 3D printer uses a laser as a energy source which selectively melts powdered plastic material, fusing them together into a 3D printed part. This technology is part of Laser Powder Bed Fusion (LPBF), one of the most advanced and reliable technologies in the 3D printing field of additive manufacturing.
Using 3D data from a CAD model, the laser melts the plastic material exactly at the predifined areas in the powderbed of the additive manufacturing system. After the melting process is completed, the building platform is lowered, and a new layer of powder is added. This process repeats layer by layer until the part is completed.
Selective laser sintering is very popular in the field of plastics 3D printing because of its essential advantages like freedom of design, high productivity and low cost per part. In contrast with some other 3D printing technologies, such as stereolithography (SLA) and fused deposition modeling (FDM) SLS 3D printing does not require any support structures to fabricate overhanging designs. That allows the creation of very complex, almost impossible 3D printed patterns. Producing parts only requires powder and power and no binders nor agents.
