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.
| 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. |
