What can be a result of using improper layer heights in FDM printing?

Using improper layer heights in Fused Deposition Modeling (FDM) printing can lead to inconsistent print quality. When the layer height is too high, it may result in poor adhesion between layers, leading to delamination or weak spots in the printed part. This can disrupt the flow of the printing process, causing varying thicknesses and potential gaps in the print. Conversely, a layer height that is too low can lead to excessive extrusion time, causing issues such as stringing, oozing, or even clogged nozzles, all of which contribute to a lack of consistency in the final output. Therefore, maintaining the appropriate layer height relevant to the specific design and material is crucial for achieving consistent print quality throughout the printed model.
