SLS technology utilises a CO2 laser to fuse or melt together the
fine nylon powder in 0.1mm layers. The laser is guided by a computer
controlled mirror whose data is fed from an stl. file.
The Build Platform and the model gradually step downwards by the
layer thickness, as the Delivery Chambers alternately rise to provide
a fresh charge of powder for the roller to accurately spread over
the Build Area.
On cooling the finished models are broken out of the 'Cake' of unsintered
powder and brushed clean.
