Beam offset on exposure of the enclosed areas of the layer
During exposure of the enclosed areas of the layers, the beam offset displaces the
path of the centre of the laser beam from the nominal contour by the value entered
towards the inside.
Exposure types
The exposure types contain defined material and process parameters for the
exposure. Depending on the parameter settings, these types affect the mechanical
properties and the surface finish quality of the part, as well as the building speed. An
exposure type can be allocated to any part.

For the different powder materials there are various exposure types defined by
EOS that are embedded in parameter sets.
See section
5, Exposure types for the original EOS parameter sets (without PPP)
,

.
Using the
Exposure editor
module custom, customer-specific exposure types can
be prepared. See section
5, Exposure editor
