Increase continuous walls and bottom layers, correct under-extrusion and seams, orient to reduce leak paths, and pressure-test safely before using the part.
Start hereIncrease continuous walls and bottom layers, correct under-extrusion and seams, orient to reduce leak paths, and pressure-test safely before using the part.
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
Inspect the model and sliced preview for thin walls, holes, and open surfaces.
Keep the problem and target visual open while you make this change.
Why this matters
Tiny paths remain through sparse shells.
Setting or checkWall count
Continuous perimeters are more important than high infill.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 2 of 8
Calibrate flow, temperature, and layer bonding.
Keep the problem and target visual open while you make this change.
Why this matters
Adjacent lines do not seal.
Setting or checkBottom layers
Increase until the base is fully dense.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 3 of 8
Use multiple continuous perimeters and adequate bottom layers.
Keep the problem and target visual open while you make this change.
Why this matters
Start/stop points create a continuous leak path.
Setting or checkSeam settings
Reduce gaps and scatter or hide the seam appropriately.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 4 of 8
Place seams away from the lowest pressure area when possible.
Keep the problem and target visual open while you make this change.
Why this matters
Mechanical defects open the shell.
Setting or checkTemperature / cooling
Promote strong layer fusion without overheating detail.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
Step 5 of 8
Slow outer walls and avoid excessive cooling that weakens bonding.
Keep the problem and target visual open while you make this change.
Why this matters
The printed polymer and process are not inherently certified for the application.
Setting or checkWall count
Continuous perimeters are more important than high infill.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 6 of 8
Use a safe low-pressure leak test appropriate for the part.
Keep the problem and target visual open while you make this change.
Why this matters
Tiny paths remain through sparse shells.
Setting or checkBottom layers
Increase until the base is fully dense.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 7 of 8
Apply a compatible coating only when suitable for the intended use and safety requirements.
Keep the problem and target visual open while you make this change.
Why this matters
Adjacent lines do not seal.
Setting or checkSeam settings
Reduce gaps and scatter or hide the seam appropriately.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 8 of 8
Redesign with thicker walls, ribs, fillets, or separate seals if leakage persists.
Keep the problem and target visual open while you make this change.
Why this matters
Start/stop points create a continuous leak path.
Setting or checkTemperature / cooling
Promote strong layer fusion without overheating detail.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
