Laser sintering process
Basic information on the laser sintering process
Physical process
The basic principle of the laser sintering process comprises the melting of layers of
plastic powder using a CO
2
laser.
During the laser sintering process, the plastic powder is briefly heated to a
temperature above the melting point by exposure with the laser beam. A solid body
is produced by this heating and the subsequent cooling.
In each layer the cross-section of the parts is exposed using the laser beam such that
the exposed areas are joined to the layer underneath that has already been solidified.
In this way three-dimensional parts are produced layer by layer.
