Correcting material-dependent shrinkage
To compensate for the material shrinkage that occurs during the process, the parts
must be scaled up by the magnitude of the shrinkage. In an EOS default job the
material-dependent scaling recommended by EOS is already pre-set.
Machine-specific, material-dependent scaling can be determined by comparing the
recommended scaling and the scaling actually measured on the part. This new value
for the scaling is then entered in the PSW .

1 Original size 2 Scaled up
➢ For the recommended scaling values for the individual plastic powders see
the parameter sheet.
➢ A change in the scaling values after loading the parts results in the
movement of the parts in the X and Y direction.
In this case check the job for the positioning of parts outside the building
area.
➢ Changes in the material-dependent scaling values are saved in the material
parameter set and therefore act on all jobs that are based on this material
parameter set.
