Support Extruder

support extruder

Using this parameter you can choose which extruder prints the support material and also the parts of the structure that will be printed. This parameter is divided into the following options:


Support infill extruder

First layer support extruder

Support interface extruder

Support roof extruder

Support floor extruder

Support placement

support placementconfiguring support placement


This option allows you to indicate where the supports will be generated and contains the following options:

Touching the printing surface: the support material is only printed on the printing surface.

Everywhere: supports are generated under all areas of the model that require support.




PVA | BVOH    As they are soluble materials, the supports can be printed everywhere.

Support overhang angle

support overhang angleconfiguring support overhang angle


the minimum angle where all overhangs will have supports.

  • 0º will make all the overhangs have support
  • 90º will not generate any supports





Because they are materials with low printing temperatures and are able to use the layer fan, the minimum printable angle is 60º

The minimum printable angle for these materials is 50º due to their high thermal requirements for printing.



Thanks to the fibers in these materials, overhangs can be printed with better angles than their versions with fibers, up to 55º.



0.8 | 1mm

it is advised to reduce the overhang angle by 5º.

Support pattern

support pattern

types of support pattern

There are different patterns for printing supports. Patterns influence the quality of the support, making it stronger or easier to remove.

Recommended patterns:

Grid:  indicated for water-soluble materials such as PVA and BVOH. It creates highly resistant structures that are easy to dissolve.

Zig Zag:  recommended for non-water soluble materials. The structure is not very resistant but very easy to remove, leaving minimal detail on the contact surface.

Support density

support density

examples of support density

the amount of material used to fill the supporting structures. Higher density means stronger supports but also more difficulty in removing the piece.

Support Z Distance

support z distanceexample of support z distance parameter


With this parameter, you can configure the distance between the supports and the model along the Z-axis. It is divided into two options:

Top distance:  the distance between the top of the support and the piece.

Bottom distance: the distance between the bottom of the support and the piece.

Distance support in X/Y 

support x/y distance

Allows you to adjust the space between the supports and the piece in the X and Y directions. Increasing this value prevents the support structure from mixing with the walls that do not require support.
