Exposure
During the exposure of a layer, the contour, i.e. the periphery of the part and the
enclosed area of the layer are exposed using a laser beam. During this process the
plastic powder is melted and bonds to the layer underneath.
During the exposure, a curing zone of solidified plastic powder forms around the
laser beam.
For the dimensional accuracy of parts, the size of the curing zone must be taken into
account during exposure. It is dependent on the powder material used and the
exposure type selected. The dimensional variation is compensated by offsetting the
laser beam.
