What is the best « layer height » for your printer

A lot of questions can rise when it comes to tweaking our slicer parameters.

Adjusting the layer height value to have the best possible quality can become tricky.

What is the Max and Min layer height for my printer?

To answer this question we need to take into account the nozzle size of your hotend.

Printing with a layer height too low might cause the plastic  to be pushed back into the nozzle and the extruder will struggle to push the filament. In the worth cas the plastic can expand/react/change state inside the hotend.

Depending on your extruder, it can also damage the filament preventing it to properly push the filament.

Also in the opposite situation, if the layer height is too high, the layers won’t stick properly to the previous layer resulting in a poor finish/poor rigidity  of your 3D model.

An easy way to determine the Min and Max layer height is to apply this simple formula:

Min Layer height =  1/4 nozzle diameter

Max Layer height = 1/2 nozzle diameter

Once you have this calculated you can test to print a calibration pattern and adjust the layer height slightly.

Optimal layer height for your Z axis

Layer height also depends on your mecanics and electronic settings:

Indeed, the following things will impact layer height:

  • Firmware Settings  (micro stepping)
  • Electronic settings (motors steps per turn)
  • Z axis threaded rod steps

A great calculator is available online and it will give you compatible layer heights for your machine:

At the bottom of the page you will see « Optimal layer height for your Z axis »

This calculator helps  to determin if the amounts of steps performed per layer height is an integer value.

As the firmware is only able to drive an integer amount of steps, using a layer height requirering a float value will cause a potential cumulative error (depending on the firmware) and the total height of your printed part can be smaller/higher than expected.
