A detailed STLBEAST repair guide to reduce overgrown bottom layers while preserving plate adhesion. Learn how to recognize the symptom, rank the likely causes, apply safe fixes in order, verify the result, and prevent the failure from returning.
Start hereStart with use a raft/support when appropriate, then reduce bottom exposure carefully. Confirm the result with a short representative test before changing additional settings.
First safe actionRun the first safe check and change one variable at a time.
Proof targetA small representative test no longer shows the original symptom.
Match the failed area to the visual before changing a setting.
Repair progress0 of 8 complete
Step 1 of 8
Document the failure and confirm that it matches this guide: Bottom edges flare outward and holes near the plate close up.
Keep the problem and target visual open while you make this change.
Why this matters
Light bleed enlarges early layers.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
The base remains attached but dimensions match the model.
Step 2 of 8
Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.
Keep the problem and target visual open while you make this change.
Why this matters
Overgrowth extends farther up the part.
Setting or checkBottom exposure
Use enough for adhesion without excessive base growth.
Expected result
The same test succeeds at least twice without a new artifact appearing.
Step 3 of 8
Check bottom exposure too high. Use a raft/support when appropriate.
Keep the problem and target visual open while you make this change.
Why this matters
Functional geometry sits inside the overexposed zone.
Setting or checkLift speed/distance
Control peel force and allow complete release.
Expected result
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
Step 4 of 8
Check too many bottom layers. Reduce bottom exposure carefully.
Keep the problem and target visual open while you make this change.
Why this matters
Generic shrink values are inaccurate.
Setting or checkSupport/contact size
Match the cross-section and suction forces of the part.
Expected result
The successful values are recorded with printer, nozzle, material, slicer, and date.
Step 5 of 8
Inspect model placed directly on plate. Lower bottom-layer count.
Keep the problem and target visual open while you make this change.
Why this matters
Light bleed enlarges early layers.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
The base remains attached but dimensions match the model.
Step 6 of 8
Rule out compensation not calibrated. Calibrate bottom compensation.
Keep the problem and target visual open while you make this change.
Why this matters
Overgrowth extends farther up the part.
Setting or checkBottom exposure
Use enough for adhesion without excessive base growth.
Expected result
The same test succeeds at least twice without a new artifact appearing.
Step 7 of 8
Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.
Keep the problem and target visual open while you make this change.
Why this matters
Functional geometry sits inside the overexposed zone.
Setting or checkLift speed/distance
Control peel force and allow complete release.
Expected result
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
Step 8 of 8
Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.
Keep the problem and target visual open while you make this change.
Why this matters
Generic shrink values are inaccurate.
Setting or checkSupport/contact size
Match the cross-section and suction forces of the part.
Expected result
The successful values are recorded with printer, nozzle, material, slicer, and date.
