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

 

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.

 

Recommendations:

Materials

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

---

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

 

Recommendations:

Material:
Tough PLA  PLA | PET-G  TPU	Because they are materials with low printing temperatures and are able to use the layer fan, the minimum printable angle is 60º
PA | PP | ABS	The minimum printable angle for these materials is 50º due to their high thermal requirements for printing.
PAHT CF15 PP GF30	Thanks to the fibers in these materials, overhangs can be printed with better angles than their versions with fibers, up to 55º.

Hotends
0.8 | 1mm	it is advised to reduce the overhang angle by 5º.

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

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

 

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 

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.
