Complete filling with border offset Combined inner hatch and border offset
The combination of the three basic types generates a hollow structure, which realises a defined
wall thickness in the contour plane (XY) by border offset, and a defined wall thickness in the
building direction (Z) by skin fill hatching. The remaining hollow space is filled with inner
hatching. In order to reduce build time, an incompletely self-contained structure, e.g. the grid
structure on the right, is especially suited.
Finally, the way hatching is generated depends on the process principles of the chosen machine
as well as on the material used by the machine. Thus, the VisCAM RP hatch generator supports
all significant methods of hatching of the prevalent RP-procedures. The methods of hatching can
be adapted flexibly by the subsequently listed parameters to the particular procedure.
Inner hatch
• Hatch angle: Determines the angle of hatching in relation to the X-axis. Some RPprocedures
are restricted to the use of hatches parallel to an axis. Independent from the
process in use, the hatch generator always supports any hatch angles (e.g. 23.75
degrees).
• Hatch space: Defines the distance between individual hatches. In order to generate a
self-contained contour plane, this value should be half the beam diameter (tab page
Process) at the maximum.
• Border space: Defines the distance from the hatches to the boundary of the contours.
The border space depends on the chosen kind of contour contact.
