Three-dimensional objects produced from powdered materials, using selective laser sintering technology.
An electronic analog of a part is created by means of any CAD system (AutoCad, Unigraphics, Solid Works etc.) Specialized SLS machine software splits the CAD model into layers with 0.0059” thickness.
Sintering (Production Process)
- A powder layer 0.0059” thick is applied on the movable bottom of the SLS machine processing chamber.
- The machine’s laser burns the part’s first layer contour.
- The movable bottom moves down 0.0059”.
- A new layer is applied over the first layer.
- The machine’s laser burns the part outline for the second layer and “cauterizes” it to the first layer.
- Heating lamps help layers adhere.
- The production cycle is repeated until complete formation (sintering) of the new part.
- The container is pulled out of the SLS machine with the finished model.
- Excess powder is removed by compressed air.
- The sintered model, a new physical prototype, is obtained!
Average sintering speed – 0,98”/hour.
It takes 10 hours to manufacture model with dimensions 7,87”х7,87”х7,87”.
