In every manufacturing process, there is a parameter that determines the quality of the product, in 3D printing this parameter is the layer height. In this article, you will learn all about layer height and how to set it correctly.

What is and how does layer height affect the model
The layer height defines how thick the layers of the printed model will be.
The initial layer height parameter allows you to modify the thickness of the first layer. A thicker first layer improves adhesion to the print surface.
Note: Layer height values are automatically shared between extruders so it will only be necessary to indicate it in one of the heads.
The thickness of the layers affects different physical aspects of the part and the printing process:
Reducing the layer height makes the part surface smooth and continuous. It also allows to obtain a greater level of detail along the Z axis, which has a significant influence on curved surfaces, on ramps and overhangs.
On the other hand, the lower the layer height, the longer the printing time. Time increases inversely proportional to layer height.
the thicker the layers, the greater mechanical resistance of the piece, this is due to the reduction of weld points, which are the weak areas between layers.
In the following graph. how the mechanical resistance varies depending on the diameter of the hotend and the height of the layer:
For post-processing tasks such as sanding and painting, it is desirable that the layer height is very small to save time in these processes. If you want to know more about how to sand or paint your model, visit the following article: Post-Processing
Correctly set the layer height
|BCN3D Stratos contains recommended profiles with standard parameters for different layer heights, for each BCN3D printer and hotends.|
When selecting a layer height, it is necessary to know the physical limitations that must be taken into account:
The diameter of the hotend
The minimum layer height
To avoid problems, vary the speed in steps of 5mm / s and do not exceed the threshold of print speeds of the material.
