9 Pro Tips to Combat Warping in PLA, ABS & More!

Welcome tech enthusiasts and 3D printing fans! Dive deep into the world of 3D printing and say goodbye to the pesky challenge known as warping. If you’ve tinkered with a 3D printer, you’re likely no stranger to this issue. But, breathe easy, there are numerous strategies to minimize warping to the extent that you can achieve consistently perfect prints. In this piece, we’ll dissect the ways to ensure warping is a problem of the past.


To combat warping or curling in your 3D prints, it’s crucial to have an enclosure that regulates the surrounding print temperature and averts any swift cooling, which results in material contraction. Choose the right temperature for your build plate based on the filament in use. Ensure a pristine build plate and use binding agents to guarantee the print adheres securely.

Defining Warping/Curling in 3D Printing
Warping or curling arises when the foundational layer of a 3D print begins to twist upward, detaching itself from the build plate. This leads to compromised dimensional precision and might jeopardize both the functionality and aesthetic of a 3D design. The primary culprit? Material shrinkage due to sudden temperature fluctuations.

What Triggers Warping & Lifting in 3D Prints?
The predominant causes of warping and curling stem from temperature variations which induce shrinkage in your thermoplastic filament, compounded by inadequate adhesion to the build platform. Here are specific factors leading to 3D printing warping:

– Swift temperature transitions.
– Inadequate or inconsistent bed temperature.
– Chilled drafts directly impacting the model.
– Insufficient grip on the build plate.
– Less than ideal cooling configurations.
– Misaligned build plate.
– Build surface tainted with dirt or particles.

Whether you’re dealing with an Ender 3, Prusa i3 MKS+ or another 3D printer, the challenges and solutions remain consistent.

Combatting Warping in Various Filaments – PLA, ABS, PETG & Nylon
1. Incorporate an Enclosure to mitigate abrupt temperature variations.
2. Adjust Your Heated Bed Temperature appropriately.
3. Utilize Binding Agents ensuring models remain fixed to the plate.
4. Turn off Cooling for initial layers.
5. Opt for a Warmer Surrounding Temperature while printing.
6. Level Your Build Plate correctly.
7. Maintain a Spotless Build Surface.
8. Eliminate Drafts stemming from windows, doors, or HVAC systems.
9. Implement a Brim or Raft.

Rescuing a Warped 3D Print – PLA Approach
Should you encounter a warped 3D print, employ a combination of heat and pressure. Place the 3D print on a flat metal surface resembling its original position on the build plate. Uniformly heat the model with a hair dryer for around a minute. Press down and reshape the print. Hold for a few moments until cooled, and repeat as necessary.

Preventing PETG 3D Prints from Warping
For PETG, consider:
– Turning off cooling fans for early layers.
– Opting for adhesive build surfaces like BuildTak.
– Employing quality adhesive agents.
– Reducing printing speed during the initial layer.
– Modifying your printing and bed temperatures.
– Drying your PETG filament to minimize moisture.

Keeping Nylon Filament Warp-Free
For optimal results with Nylon, invest in a heated enclosure and consider using finer layer heights. Reduce your print speed, ensure your heated bed aligns with your Nylon filament’s requirements, and experiment with Blue Painter’s Tape to enhance adhesion.

Addressing PLA Warping on PEI Surfaces
For PEI surfaces experiencing PLA warping, cleanse with isopropyl alcohol. For larger designs, warm the bed longer, ensuring even heat distribution. Gently sand the PEI with ultra-fine sandpaper for enhanced adhesion.
