Hollowing thickness
- The thickness of the resulting
shell. The minimum value is 1 mm.
Hollowing accuracy
- A trade-off between accuracy and
performance. If a low hollowing accuracy is set, the
resulting model wall thickness may be uneven. Therefore
a higher hollowing accuracy is recommended for a small
hollowing thickness (for thin shells) to ensure minimum
wall thickness.
Hollowing closing distance
-Hollowing suppresses
cavities narrower than the closing distance threshold,
and it also fills in sharp concave corners of the inner wall,
from which it would otherwise be difficult to remove the
uncured highly viscous resin.
Adding drainage holes
- Drainage holes can be added by left-clicking on the object when the
SLA hollowing gizmo is active. The holes can later be repositioned by dragging them on the mesh.
You can remove holes by right-clicking on any of them.
Each hole is always perpendicular to the surface and its diameter and depth can be configured -
the current settings will be used for newly placed holes.
If the input mesh is broken, the hole drilling algorithm may refuse to proceed in order to prevent
program crashes or incorrect results.
Confirm and preview the hollowed mesh
- The hollowing and hole-drilling are performed after
the Preview hollowed and drilled model button is pressed. Note that both hollowing and hole-
drilling are computationally expensive tasks and will take some time, especially with complex
models. In case the user does not press the button himself, the hollowing and drilling will be
performed during the slicing process.
The
Clipping plane tool
can be used to peek inside an object (the same tool is present in the SLA
support points editing gizmo). Move the slider from left to right to move the clipping plane. You
can review the hollowed geometry and place the drainage holes appropriately.
