Selective Laser Sintering (SLS) 3D Printing

Laser Sintering, also known as Selective Laser Sintering (SLS), is among the most versatile and frequently used 3D printing technologies. As a self-supporting build methodology, SLS enables the production of complex geometries, such as monolithic designs, lightweight components, and mass-customized products that could not be manufactured in any other way.

Structures? Not in SLS 3D Printing!

Selective Laser Sintering (SLS) 3D printers make use of a CO2 laser and a thermoplastic polymer powder to build parts. Because of the high power, the laser moves along a "point-to-point" pattern, solidifying the whole cross-sectional area of a layer. After the layer is complete, the re-coater deposits a new layer of powder and the build platform moves down one layer in height. The process is then repeated until the part is complete.

  • Low Volume Production
  • Prototypes with mechanical properties to rival those of injection-molded parts
  • Economical production of unique, complex designs built as one-off products or in small batches
  • Lightweight designs using complex lattice structures

Technical Specification
Maximum Build Volume Dimensions are unlimited as components may be composed of several sub-parts. The build area of our largest machine is 381 x 330 x 460 mm
Dimensional Accuracy ±0.3% (with a lower limit of ± 0.3 mm)
Minimum Wall Thickness 1 mm, but living hinges are possible at 0.3 mm
Surface Structure Unfinished parts typically have a grainy surface but all kinds of fine finishes are possible. Laser-sintered parts can be sandblasted, coloured/impregnated, painted, covered, and coated.
