Layer height

The layer height - one of the most often changed settings - is the thickness of one printed layer (in mm). With a thinner layer height you will 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 as a bigger layer height than the model on the right.

There are 3 typical settings for indication:

  • 0.06 mm: A high resolution, at which the layers are barely visible.
  • 0.1 mm: Used for most prints. The golden mean between a fast print and good quality.
  • 0.15 - 0.2 mm: Used for fast prints. At this speed the layers still create an overall usable part while minimizing the print time.

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. The disadvantage of using a thicker initial layer can be that the first layer is a little bit too wide (over extruded). Depending on the purpose of your print you may decide to decrease the initial layer height. In this case it is even more important to ensure the build plate is leveled correctly.

Line width

Line width defines the width of a single printed line, which should be almost equal 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.

Tip: If you use a unavailable 3rd party nozzle size, set the line width to equal the nozzle size.

The model on the left has a smaller line width than the model on the right.

The line width can be set for different parts in the print:

  • Wall line width: The width of a single wall line. The line width of the inner and outer walls can be adjusted separately.
  • 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 line width: The width of the skirt 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.
