Overhang Curling and Drooping

Fix upward-curled edges, rough overhangs, and nozzle collisions on unsupported geometry.

Start hereImprove cooling, lower temperature, slow overhangs, and reduce layer height—then support or reorient geometry that exceeds the printer/material capability.

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.

Problem, repair steps and target result for overhang curling and drooping — Match the failed area to the visual before changing a setting.

Repair progress0 of 7 complete

Step 1 of 7

Check part-cooling fan operation and duct alignment.

Visual reference while completing step 1 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

New overhang line stays soft and lifts.

Setting or checkOverhang speed

Slower gives cooling time.

Expected result

Overhang edge remains flat.

Step 2 of 7

Run an overhang test using the material profile.

Visual reference while completing step 2 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

Material cannot hold the unsupported shape.

Setting or checkOverhang flow

Avoid excessive material on unsupported edges.

Expected result

No nozzle contact occurs.

Step 3 of 7

Lower temperature in small steps while checking bonding.

Visual reference while completing step 3 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

Line is deposited too fast or too heavily.

Setting or checkFan

Use material-appropriate cooling.

Expected result

Underside is consistent through the target angle.

Step 4 of 7

Slow overhang speed and reduce overhang flow if the slicer supports it.

Visual reference while completing step 4 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

Each layer extends too far beyond the last.

Setting or checkLayer height

Smaller layers reduce each unsupported step.

Expected result

Layer strength remains acceptable.

Step 5 of 7

Use a smaller layer height for finer support between layers.

Visual reference while completing step 5 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

Settings cannot overcome extreme spans.

Setting or checkOverhang speed

Slower gives cooling time.

Expected result

Overhang edge remains flat.

Step 6 of 7

Reorient or add support for critical angles.

Visual reference while completing step 6 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

New overhang line stays soft and lifts.

Setting or checkOverhang flow

Avoid excessive material on unsupported edges.

Expected result

No nozzle contact occurs.

Step 7 of 7

Prevent warping so the nozzle does not collide with raised geometry.

Visual reference while completing step 7 of overhang curling and drooping — Keep the problem and target visual open while you make this change.

Why this matters

Material cannot hold the unsupported shape.

Setting or checkFan

Use material-appropriate cooling.

Expected result

Underside is consistent through the target angle.

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.

Prove the repair with a small test

Test modelSmall overhang and support coupon

Setup

Use the final layer height, support interface and cooling profile.

Pass condition

Supports detach predictably and the underside is intact.

If it still fails

Supports fuse, collapse or leave severe scars.

Recheck visual diagnosis

Complete the repair steps, run the proof test, and record the result.

Only if the proof test still fails
