Suction failures happen when a resin model traps pressure against the FEP or film. The solution is usually better hollowing, drainage, orientation, and support strategy.

Start with observation first. Do not change multiple slicer settings at the same time or the real cause becomes harder to find.
Use these as practical starting points, then tune against your printer, material, nozzle, layer height, and model geometry. The safest workflow is one controlled change at a time.
| Setting Area | What to check |
|---|---|
| Drain holes | use enough size and placement for resin flow and cleaning. |
| Orientation | avoid large flat suction faces. |
| Lift speed | slower for large cross-sections. |
| Support density | stronger where peel forces are highest. |
| Exposure | tune supports and detail together. |
Slice a cross-section preview and confirm no sealed cups face the film. Run a smaller hollow test before a large display piece.
After the validation print succeeds, save the exact printer, material, slicer, nozzle, layer height, support, bed adhesion, and cooling setup in Profile Vault so the fix becomes repeatable.
Only use tools that match the diagnosis. Common helpful categories include PEI cleaning supplies, filament dryers, nozzles, deburring tools, calipers, support-removal tools, and safe resin handling equipment.
