SELECTIVE LASER SINTERING
Selective Laser Sintering or SLS is a rapid prorotyping technology that turns 3D CAD data into physical parts. SLS is an additive technology that uses powdered Nylon 12. Parts produced are light-weight, highly durable, and both heat and chemical resistant, making SLS an excellent choice for producing production parts without the expense of tooling.
The SLS process begins by splitting 3D CAD data into thin cross-sections or layers. The data is then transferred to the SLS additive manufacturing equipment. The machine then begins to create the first layer. After a leveling roller spreads a thin layer of powdered material across the powder bed, a CO2 laser traces the cross-section on the material. As the laser scans the surface, material is heated and fused together. Once a single layer is complete, the powder bed is lowered to make room for the next layer. More material is introduced from the powder catridge and rolled out smooth, while unused material is recycled. The process is repeated, building layer upon layer until the part is complete.
As SLS parts are built, they are encompassed by unsintered powder which provides supplemental strength and eliminates the need for support structures. Complex designs and assemblies once thought and impossible are now being redesigned with SLS at cost effective integrated structures solid concepts and new factures parts utilizing nylon with property enhancing filters to create rugged SLS parts suitable for a variety of protoype and production applications.
Materials: PA Nylon (for regular applications), Glass filled Nylon (for higher strength applications)
