A detailed STLBEAST repair guide to find every disconnected region before printing. 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 island detection, then scrub every layer region. 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: Small fragments or missing features appear because new layers begin in mid-air.
Keep the problem and target visual open while you make this change.
Why this matters
The algorithm did not detect a small region.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
Every island is supported or connected to cured geometry in the layer sequence.
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
A feature appears before its connection.
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 automatic supports missed an island. Use island detection.
Keep the problem and target visual open while you make this change.
Why this matters
The island cures on the film instead.
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 orientation creates isolated starts. Scrub every layer region.
Keep the problem and target visual open while you make this change.
Why this matters
Hidden geometry is not supported.
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 support tip too far away. Add manual supports.
Keep the problem and target visual open while you make this change.
Why this matters
The algorithm did not detect a small region.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
Every island is supported or connected to cured geometry in the layer sequence.
Step 6 of 8
Rule out hollowing creates internal islands. Reorient difficult features.
Keep the problem and target visual open while you make this change.
Why this matters
A feature appears before its connection.
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
The island cures on the film instead.
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
Hidden geometry is not supported.
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.
Controlled test log
Change one variable, then record what happened
This keeps temperature, retraction, speed, mechanical, and material tests from blending together. The history stays private in this browser.
