The layers of my 3D print split and separate from each other

How do you prevent layer separation and splitting?  

We explain the two most common causes of layer separation and splitting. We also look at possible solutions to these problems.

• Layer height is too large

  The layers you print must be pressed together well so that they can adhere to each other. As a standard rule, you can assume that the layer height should be at least 20% smaller than the diameter of the nozzle, or printhead. If not, the layers will not adhere properly to the layer it is being printed on.
  So if you notice that the layers are not bonding properly and are starting to peel off, this is one of the first causes to look at. When the proportions are correct, try to solve the problem by lowering the layer height settings until you notice that the layers adhere well together.

• Print temperature is too large

  If you are sure that the layer height is not too high, the problem could be with the print temperature. If the filament is not printed hot enough, the layers cannot adhere well to each other and therefore become separated from each other. Always check whether the print temperature is suitable for the filament you are using. Depending on the type of material, the desired temperature may deviate. Increase the print temperature to see if it improves adhesion.

• Print speed too high

  It is also important to take the print speed in relation to the temperature into account. If the print head moves too quickly over the layers, the plastic will not have time to properly bond to the previous layer. Try decreasing the print speed in steps of 10mm per second.

If these solutions do not work and you have your 3D printer in an open space, enclosing the printer can also help. This keeps all the heat at the printer and prevents any draft that prevents the material from bonding properly. Repairing a print with crevices can also be solved by applying a coating to your print.
