If you were printing a 1.0mm wide wall with a 0.4mm nozzle, there may be a small internal gap between the perimeters on either side of the wall. Internal thin walls are small voids or gaps that may appear on the inside of your model. For example, if your nozzle was 0.4mm wide and you were printing a wall that was only 0.2mm thick, this would be an external thin wall. External thin walls are very thin features that are visible from the outside of the model.

We have set up a factory file that contains this model along with the initial settings for this tutorial. This model contains several thin, tapering blades that connect to a narrow hub in the center of the model.
For this tutorial, we are going to use the “Toy Open Water Turbine” model by user Non-ICE. So regardless of what type of models you are printing, it can be useful to learn about these special features. Many parts also contain sharp or tapering edges that could produce very thin extrusions. For example, a large part may still contain thin walls within the model itself. First of all, it’s important to understand that even large models can have difficulty with small features.
