The layer height is one of the most frequently changed settings. It is the thickness of one printed layer in millimeters. With a thinner layer height you can increase the quality of the print, leading to a smoother surface and more detail visible in the Z-direction (height) of the model. On the other hand, by using thicker layers you can decrease the print time substantially.
The model on the left has a smaller layer height than the model on the right.
The recommended mode allows the user to easily choose a layer height compatible with the current print core and material configuration. The number of available layer heights options differ per configuration. The custom mode allows the user to completely customize the layer height.
Note: In the custom mode, choose a layer height close to your desired custom layer height. The profile contains layer height dependent settings, like temperatures, to ensure a high-quality print.
Initial layer height
This setting defines the height of the first layer of your print. The initial layer height is usually thicker than the layer height to create a stronger adhesion with the build plate. When the model has a lot of detail on the first layer, it might have a decreased quality because of the thicker layer. This limitation can be compensated for with the "initial layer horizontal expansion" setting, which is found under the Shell category.
Line width defines the width of a single printed line, which should be close to the nozzle size. Based on the line width, the extrusion rate is adjusted, which means that it will automatically calculate how much material must be extruded.
Example 1: Decrease the line width slightly of the outer wall to allow sharper detail on the model.
Example 2: An increased line width of the infill allows the infill to print slightly faster.
Tip: If you use an unavailable third-party nozzle size, set the line width to equal the nozzle size.
The exact same model with line widths of 0.25, 0.4 and 0.8 nozzles.
The line width can be set individually for all line types available:
- Wall line width: The width of a single wall line. The line width of the inner and outer walls can be adjusted separately.
- Top surface skin line width: This line width is only available when a top surface skin is used.
- Top/bottom line width: The line width with which the top and bottom layers are printed.
- Infill line width: The line width of all infill material.
- Skirt/brim line width: The width of the skirt or brim lines.
- Support line width: The line width of support structures.
- Support interface line width: The width of a single support interface line.
- Prime tower line width: The width of a single prime tower line.
- Initial line width: The width of lines on the initial layer.
