Selective Laser Sintering, or SLS, is a distinctive advanced manufacturing process that forms solid objects by compacting and fusing material using heat and pressure, but crucially, without melting the material completely. This technology is widely regarded in the industrial 3D printing realm for creating high-quality, functional end-use parts that boast impressive mechanical properties. SLS is particularly well-suited for intricate designs and is a cost-effective alternative to traditional injection moulding.
In SLS printing, a fine layer of powder material is spread across the building platform inside a heated chamber. The temperature within this chamber is maintained just below the material’s sintering point. A high-powered laser then selectively sinters the powder, binding the particles together to form a solid layer corresponding to a cross-section of the printed part. This process is repeated layer by layer, with each new layer bonding to the one beneath it until the final shape is achieved. Once printing is complete, the part is carefully extracted from the surrounding powder, and any remaining powder is removed. The part can then be taken for additional finishing per client requirements.
SLS printing primarily utilises materials like Nylon and Glass-Filled Nylon, offering a range of properties:
