Elephant Foot Fix
Correct swollen first layers, oversized bottoms, tight holes near the bed, and rounded lower edges.
Fix Z offset and bed temperature first, then use first-layer compensation or a small model chamfer for the remaining predictable expansion.

Know what to do now—and what comes next
Follow one controlled path. Do not stack unrelated changes before the proof test.
- 1Confirm the visual clue
Compare the failed area with the problem and target visuals.
- 2Run the safest first checks
Run the first safe check and change one variable at a time.
- 3Print the proof test
A small representative test no longer shows the original symptom.
- 4Escalate only if needed
Use the next-route guides only when the original symptom remains.

Before you change settings
- Confirm the exact printer, material, nozzle or resin, slicer, and recent hardware changes.
- Clean and correctly seat the build plate before adjusting Z offset or flow.
- Return extreme overrides to a known profile and change one variable at a time.
- Use a small calibration object or representative section before repeating a long print.
What it looks like
- Bottom edge flares outward
- Holes are tight only near the bed
- First layer has heavy ridges
- Part dimensions improve above the first layers
Most likely causes
- Nozzle too closeExcess squish pushes material outward.
- Bed temperature too highLower layers remain soft under weight.
- First-layer flow too highToo much material is deposited.
- No cooling or heavy part massBase deforms before solidifying.
- No model relief/chamferSharp designed edge has no process allowance.
Repair sequence
Work from top to bottom. Stop when the failure is resolved, verify it with a small test and record the successful setup.
- Step 1Run the nozzle-too-close test and correct Z offset.
- Step 2Return first-layer flow to the validated profile.
- Step 3Reduce bed temperature in small material-safe steps after adhesion is secure.
- Step 4Use normal cooling timing for the material.
- Step 5Apply slicer elephant-foot compensation conservatively.
- Step 6Add a small chamfer to the model when design control is available.
- Step 7Validate fit at the final print orientation.
Settings to review
| Setting | How to use it |
|---|---|
| First-layer compensation | Use only after height and temperature are correct. |
| Bed temperature | Lower carefully without losing adhesion. |
| Initial layer flow | Avoid using excess flow for adhesion. |
Material notes
Often solved by Z offset and bed heat.
Avoid over-squish and excessive adhesion.
Thermal control can complicate base tuning.
Printer context
Check bed seating, gantry alignment, belts, wheels and first-layer consistency across the plate.
Start with the official profile; inspect belt balance, input shaping, flow, pressure advance and chamber conditions.
Confirm delta calibration, tower movement, belt tension, effector stability and full-bed mapping.
Use resin-specific exposure, lift, support, temperature, wash, cure and protective procedures.
Where to look in the slicer
Quality, Strength, Speed, Support and Filament; use built-in calibration for temperature, flow and pressure advance.
Print, Filament and Printer Settings; inspect the layer preview before export.
Quality, Walls, Top/Bottom, Material, Speed, Travel, Cooling, Support and Adhesion.
Printer/resin profile, exposure, lift/retract, support contact, raft, hollowing and drain settings.
Controlled test method
Do not repeat the full print while guessing. Use a small test that reproduces the same feature and record the result.
- Save the current profile or photograph every relevant setting.
- Choose one suspected cause from the ranked list and change only the matching variable.
- Print the smallest useful test with the same material, nozzle, plate, and environment.
- Compare the result with the target visual, keep the winning change, and then test the real model.
Confirm the repair before repeating the full print
Use the final plate, material, mesh and first-layer profile.
Lines join evenly in the centre and corners, with no scraping, gaps or lifting.
One or more zones remain loose, transparent, ridged or detached.
Recheck plate cleanliness, mesh, Z offset and first-layer flow in that order.

- Bottom edge is square.
- Hole/peg fit is consistent through height.
- Adhesion remains reliable.
- Compensation does not undercut the base.
Choose a result after the print so the guide can point you to the correct next action.
Prevent it next time
- Use a first-layer calibration pattern.
- Save plate/material profiles.
- Design a base chamfer for precision parts.
- Do not rely on very high bed heat for adhesion.

Frequently asked questions
Will elephant-foot compensation fix a scraping nozzle?
No. Correct Z offset first.
Why only on large parts?
More heat and weight can keep the base soft longer.
Can I sand it off?
Yes for one-off parts, but settings/design correction is better for repeatability.
