SLS (Selective Laser Sintering)

Home - Our Services - 3D Printing - SLS (Selective Laser Sintering)

SLS produces strong models. It uses Polymide which is a Nylon material. The maximum build size for SLS printing is 200 x 250 x 330mm. We only run our SLS machine twice a week as it requires a full build in order to operate cost-effectively as a consequence the lead time on SLS is longer than the other printing technologies we use.


Selective laser sintering (SLS) is used to build your design with nylon 12. The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model.
