How to Avoid Warping When 3D Printing

3D Printer Troubleshooting Guide: Warping

How do I stop my 3D prints from warping?

The best way to avoid warping is by using a heated build plate. This keeps the material at a temperature just below the point where it solidifies (the glass transition temperature), ensuring it stays flat and connected to the build plate. When you use a heated build plate it is important to use the right temperature.

How do I stop PLA from warping?

To avoid warping with PLA, the print bed should be properly leveled, the distance between nozzle and print bed should not be too far, the print bed temperature should be high enough, the print bed adhesion should be good enough and the ambient temperature should be as homogeneous as possible.

Why is my PLA warping?

The problem occurs because the temperature differences between layers of extruded plastic are too big. This, in turn, creates tension within the model, and when it gets to be too much, lower layers start to drag or lift, creating a warp.

What temp does PLA warp?

As for various materials, PLA undergoes quite significant dimensional changes even at 70 °C (158 °F). Higher temperatures caused warping and at 170 °C (338 °F) the object completely collapsed (melted).

What is the best bed temperature for PLA?

The recommended bed temperature for PLA is 70C. Having your bed level and extruder at the right height is extremely important when printing on glass.

Does PLA need cooling fan?

Cooling is one of the most important aspects of printing with PLA. Having a dedicated part cooling fan makes a huge difference in the quality of the printed parts. The freshly extruded plastic needs to cool down below the glass transition temperature as quickly as possible.

What temperature should AB beds be?

In order to print with ABS, you need a temperature controlled bed. The recommended bed temperature for ABS is 110. Instead of printing directly on the glass, it’s better to print with Kapton/PET tape.

How do you stop warping?

  1. Causes of Warping.
  2. Use a heated bed.
  3. Print in an enclosed print chamber.
  4. Choose the right location for your 3D printer.
  5. Turn off the material fan for the first few layers.
  6. Improve bed adhesion with adhesives or a suitable bed surface.
  7. Adjust your slicer settings.
  8. Thoroughly clean your print bed.

What causes PLA to curl?

PLA curling is caused by insufficient cooling at the nozzle, as well as, ironically, too MUCH cooling elsewhere on the model. Cooling causes contraction of the model, which will pull on other parts as it cools. This isn’t really an issue when it’s pullig on more, slightly less cool but solid PLA.

How can we make the quality of a 3D printed item better?

  1. Adjust the bed and set the nozzle height.
  2. Check the nozzle’s temperature.
  3. Use different building plates to create different effects.
  4. Pay close attention to your printer’s adjustment and maintenance.
  5. Handle the filament carefully.
  6. Use a slicer.
  7. Lower the printing speed.

How do I stop PETG from warping?

Use a bottle of standard hairspray and hold it about 6–8 inches (15–20 cm) away from the print bed. Apply it by sweeping the nozzle back and forth to coat the surface of the print bed in a thin layer. The stickiness of the spray will improve the grip and help prevent warping.

What causes PETG to warp?

Nozzle Temperature Too High

Nozzle temperature being too high is another one of the most common reasons behind PETG filament warping. As warping happens due to the differences in temperature between layers, a nozzle temperature that is too high can easily cause the model to warp, especially at the lower layers.

Why do my 3D prints keep failing?

Sometimes layers aren’t sticking together properly in mid print and depending on the model’s geometry it might cause a failure. This could be because you’re 3D printing at a temperature that’s a bit too low. ACTION: Increase the print temperature slightly and ensure those layers really fuse into each other.

Does PETG need an enclosure?

Overall, PETG is generally very easy to print with, as it requires no enclosure nor heated bed, making it compatible with virtually all FDM printers. It combines ease of printing with great strength and durability, making it a great filament choice for any print.

How do you clean PLA 3D prints?

We recommend rinsing the print using soapy water or isopropyl alcohol. Simply drop the print in the liquid and scrub using a sponge or paper towel. Be careful not to scrub too hard, as you could potentially discolor or damage the part.
