A screenshot of the Air Gap setting as seen in MatterControl's SETTINGS pane.

Function

The distance to skip between the support (including interface layers) and the model. For ABS and PLA a value between 0.4 and 0.6 generally works well.

In MatterControl 1.5, Z Gap was changed to Air Gap. Z Gap only worked in increments of the layer height. Air Gap can be any distance.

Parameters

  • millimeters (mm)

Can be zero.

Example(s)

For this example, Support_test.stl is the model used.

mm

In this example, the distance between the top of the support material and the bottom of the model is 0.2 mm.

​Here's an animation which will hopefully demonstrate a little better how the air gap works. As you can see, the first layer of the part is lifted up for the air gap, but then for the second layer it moves back down to where it would have been otherwise. In other words, the air gap does not shift the entire object up, only the first layer. This ensures that the first layer is loosely connected to the support, but subsequent layers are printed normally.
