A detailed STLBEAST repair guide to choose the least intrusive adhesion aid that solves the geometry problem. 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 try a brim first, then round or add mouse ears to corners. 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: Tall, narrow, warped, or low-contact parts need more bed support.
Keep the problem and target visual open while you make this change.
Why this matters
The model has too little footprint.
Setting or checkZ offset
Tune only after cleaning and leveling; use very small changes.
Expected result
The part stays attached with the minimum extra material and cleanup.
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
Corners lift as the material contracts.
Setting or checkFirst-layer speed
Slow enough to bond before direction changes pull the line.
Expected result
The same test succeeds at least twice without a new artifact appearing.
Step 3 of 8
Check contact area too small. Try a brim first.
Keep the problem and target visual open while you make this change.
Why this matters
A raft can isolate the model from the plate.
Setting or checkFirst-layer temperature
Stay inside material and surface limits.
Expected result
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
Step 4 of 8
Check sharp corners concentrate stress. Round or add mouse ears to corners.
Keep the problem and target visual open while you make this change.
Why this matters
The part is standing on an unnecessarily small face.
Setting or checkCooling
Delay or reduce early fan when the material requires it.
Expected result
The successful values are recorded with printer, nozzle, material, slicer, and date.
Step 5 of 8
Inspect severe surface irregularity. Use a raft only for severe cases.
Keep the problem and target visual open while you make this change.
Why this matters
The model has too little footprint.
Setting or checkZ offset
Tune only after cleaning and leveling; use very small changes.
Expected result
The part stays attached with the minimum extra material and cleanup.
Step 6 of 8
Rule out wrong orientation. Reorient to increase contact area.
Keep the problem and target visual open while you make this change.
Why this matters
Corners lift as the material contracts.
Setting or checkFirst-layer speed
Slow enough to bond before direction changes pull the line.
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
A raft can isolate the model from the plate.
Setting or checkFirst-layer temperature
Stay inside material and surface limits.
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
The part is standing on an unnecessarily small face.
Setting or checkCooling
Delay or reduce early fan when the material requires it.
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.
