Curling: The edges and corners of my 3D print are warped

How can you fix or prevent curling?

• Ensure good adhesion of the first layer

  Do you notice that the edges curl up immediately after printing the first layer? This can be caused by the filament not adhering properly to the print bed. Therefore, always make sure that your print bed is flat and aligned and that you use an adhesive spray. By following this link, you will find more information about good adhesion of the first layer.

• Provide good cooling

  The most common cause of curling is overheating. In short, this means that the plastic filament does not cool down quickly enough. To avoid this, increase the settings of your fan so that the filament cools down faster. Does your printer not have a fan? Then we recommend that you mount an externalfan on the extruder or purchase a manually operated fan.

• Lower the print temperature

  If you still suffer from curling after adjusting the fan, it may be that you are printing at a too high temperature or that the heated bed is too warm. In this case, we recommend that you lower the print temperature (or heated bed temperature) in steps of five to ten degrees so that the filament cools down faster.

• Print at a slower speed

  Reduce your print speed so that each individual layer has more time to cool down before printing the next layer. This is especially relevant when printing small objects where each print layer only takes a few seconds. In this case, reduce the overall print speed, or set a 'speed override' so that layers that require less than fifteen seconds are automatically printed at a lower speed.
