Why choose Selective Laser Sintering (SLS)?

One of the biggest strengths of the parts produced using the Selective Laser Sintering process is their durability – SLS 3D Printing materials offer both exceptional strength and functionality. Models produced using the selective laser sintering process can withstand rigorous testing and high temperatures (up to 150°C).

Another advantage of the selective laser sintering process is that it can accurately produce complex geometries.

The selective laser sintering process requires very little post production clean-up which means that parts are competitively priced and can be rapidly turned around in a matter of days which facilitates faster design iterations.

The selective laser sintering process is very well suited to low volume production as complicated parts can be produced in large quantities without incurring expensive tooling costs.

Please note figures provided above are expected tolerances, we cannot guarantee part tolerance. Stresses during the build and other geometry considerations may cause deviation in tolerances and flatness. Part designs with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses may be prone to significant deviations or warp.

Finishing Options

LPE has a team of experienced in-house traditional model makers and a full spray-painting booth allowing us to offer our customers a range of finishing and painting options.

  • Standard

    Components produced using the Selective Laser Sintering process are supplied with minimal post production clean up as standard and have a texture similar to very fine sandpaper.

  • Water Sealed

    SLS parts can be impregnated with a waterproof layer.

  • Colour Dyed

    It is possible to dye SLS parts in a range of colours.

  • Other paint finishes

    It is possible to give SLS parts a range of paint finishes including cosmetic (Pantone/RAL colour matching), matt, satin, spark or gloss.

  • DyeMansion (Automated Finishing)

    Automated cleaning, surfacing and dyeing are available with LPE’s end-to-end DyeMansion post-processing system.

How does SLS work?

First developed and patented in the mid 1980s, the Selective Laser Sintering process involves the creation by additive layer technology of physical models using a carbon dioxide laser on a bed of powdered material. As the powder is self supporting, no support structures are necessary.
