The downskin filter detects all bottom surfaces of a model which have to be exposed differently due to the anisotropic nature of the process. Downskins have a thickness. The detection of downskins is controlled by several parameter settings.
| Parameter | Default Value | Description |
|---|---|---|
| angle | mandatory | Specifies the angle of the surfaces which are considered downskin. |
| shrinkage | 0.4 | A filtering parameter that removes artifacts from the downskin detection. Downskin regions thinner than this setting (in mm) are not considered. |
| expansion | 0.6 | Downskin areas are expanded by a certain value in order to overlap neighboring layers. This value should be larger than the shrinkage. |
| thickness | 1 | Determines the thickness of the downskin in the Z direction. It should be a multiple of the layersize in mm in order to discretely determine how many layers of downskin are considered. |
