How to Fix Warping and Lifting

Bed temperature too low

Insufficient bed temperature causes the bottom layers to cool and contract too quickly, pulling away from the bed.

Poor bed adhesion

A dirty, unleveled, or incompatible bed surface prevents proper first layer adhesion.

Drafts and temperature changes

Cold air currents cause uneven cooling, leading to differential shrinkage and warping.

High-shrinkage materials

Materials like ABS, Nylon, and PC have high thermal shrinkage rates that make them prone to warping.

1Increase bed temperature

1. Step 1: Raise bed temperature by 5-10°C within safe limits
2. Step 2: Use recommended bed temperatures for your filament
3. Step 3: Consider a heated enclosure for high-temp materials

2Improve bed adhesion

1. Step 1: Clean bed with isopropyl alcohol
2. Step 2: Apply glue stick, hairspray, or specialized adhesive
3. Step 3: Use a textured PEI sheet for better grip
4. Step 4: Ensure proper first layer squish

3Use an enclosure

1. Step 1: Enclose your printer to maintain stable ambient temperature
2. Step 2: Block drafts from windows, AC, or fans
3. Step 3: Preheat the enclosure before starting large prints

4Design modifications

1. Step 1: Add a brim or raft to increase bed contact area
2. Step 2: Use mouse ears on sharp corners
3. Step 3: Avoid large flat surfaces when possible
