engendered by the procedure for the generation of support structure in the manner described
above. The height of the socket set-up is defined by the parameter socket height. The overall
height of the support socket results from the socket height plus the base height.
Bridges: In order to firm up small contour parts, additional bridge supports are inserted in the
support geometry. Bridges for a contour area are generated as soon as the contour dimensions in
X or Y lie below the defined bridge size. Bridge supports connect the upper corners of the
contact voxels with a continuous support edge in the direction of X or Y. Thus, the connection
of supplementary bridge supports to the part is equivalent to a partial application of wall contact
in the form of a connection line in-between two support points. In addition, the parameter bridge
height determines the number of slices over which the bridges run. With bridge height 1, bridge
supports are only generated in the slice underneath the supported area. In case of a bridge
height larger than 1, the highest layer of the bridge is engendered within the slice of the contour
part that has to be supported. All further bridges are generated in lower layers.

Pillars: In case of individual grid points with support function isolated in the support volume (i.e.
without connection to other cells or voxels with support function), supplementary pillar supports
are inserted in the support structure. This may especially occur in case of small contour isles
that project entirely over the dimensions of the bottom plane and that are not linked to other
contours of lower layers (cp. fig. on top). Pillars are generated from single support edges whose
length is defined by the pillar size. The connection of additional pillar supports to the part thus
corresponds to with a partial use of the support type pin tip.
Support intersection: In order to prevent support elements from running to close to a contour or
from permeating contours, all supports within the defined contour space are intersected with the
contours of the part. Supports whose distance to a contour is below the contour space are
shortened accordingly.

Cell size X: Defines the standard value for the size of cells in X. Due to the raster of the support
volume, the employed cell size must result in a whole-numbered quantity of cells. Hence, the
actual value for cell size in X corresponds to the largest value below the defined standard value
that still permits a whole-numbered splitting of the dimensions of the support volume in X.
Cell size Y: Defines the standard value for the size of cells in Y. Due to the raster of the support
volume, the employed cell size must result in a whole-numbered quantity of cells. Hence, the
actual value for cell size in Y corresponds to the largest value below the defined standard value
that still permits a whole-numbered splitting of the dimensions of the support volume in Y.
