SLS for 3D plastic printing
Selective laser sintering (SLS) for EOS systems
SLS uses a laser to selectively fuse layers of polymer powder, creating high-accuracy plastic parts from a 3D model. The process suits functional prototypes, short runs, and complex geometries, often with reduced dedicated support material.
How does SLS work?
A thin layer of powder is applied to the build platform. The laser fuses the cross-section, layer by layer, until the part is complete. Unsintered powder can surround the part, helping support many geometries with minimal extra structures.
Three milestones in SLS production
- Build preparation: orientation, layout, and process parameters and material choice.
- Layer-by-layer sintering: the laser fuses the polymer to match the CAD definition.
- Depowdering and finishing: the part is cleaned and can be used as-is, dyed, or finished further.
