Generating Supports

Generating Supports

Supports are necessary for printing parts in a majority of cases, as overhanging features on your part won’t print successfully without them. 

Make sure you position and scale your part as intended before generating supports. Rotating the part or scaling your part will force the regeneration of supports.


If no model is selected, all support settings will apply to the entire build. If specific parts are selected, those settings will only apply to the selected parts.



Support Presets

In the Support menu, you’ll find options to change the Strength and Density of your supports.

  • Strength entails the thickness of the beam and size of the touch points. The Default setting will vary depending on the type of material you’re printing with.

    • Low will make the beams thinner and decrease the size of the touch points relative to the Default settings.

    • Conversely, High will thicken the beams and increase the size of the touch points relative to the Default Settings.

  • Density entails the amount of supports generated. As with Strength, the Default will vary depending on the type of material you’re printing with. You can adjust the Density to High, Medium, and Low to adjust the amount of supports generated.

In most cases the Default presets will work fine for both strength and density. However, you may want to modify the strength or density in certain cases.

Auto-Generate Supports (to All)

Clicking this button will automatically generate the scaffolding for your part based off the presets defined above. 

Edit (All)

When you click Edit All, the Edit Supports sub-menu will appear. This sub-menu allows you to add, replace or modify specific support points for your scaffold. You can either choose to add points manually without the need of auto-generated scaffolding or you can edit points created by the auto-generating feature after it has completed.  

The Contact Thickness slider allows you to define the size of your support touch points, as well as the thickness of the support beam. To manually edit the size and placement of the supports:

  • Click Edit All to enter editing mode

  • While in editing mode, click anywhere on the model to add a touch point with the thickness defined by the Contact Thickness slider. A white dot will appear to indicate where the support will be generated

  • The point will turn yellow when the cursor hovers over it. In order to change the size of an existing support point, adjust the Contact Thickness slider to the desired size, and click over the existing specific point to modify

  • To completely remove a support, right click the touch point while in editing mode

Brush Remove Tool

The Brush Remove Tool allows the user to drag the cursor over the part and delete all support points within a certain radius of the cursor. The radius of the brush can be modified with either the slider or text field under Brush Tool Radius

Clear (All)

This button will delete any scaffolding and cone supports that have already been generated for the selected part. 


This button will pull up an advanced scaffold support settings menu that will present different support parameters for your desired results.

Click Apply to finalize the changes, but there are also options to Cancel and Reset the changes.


Custom Support Profiles

User can create custom supports and save them as profiles to use for future prints. To do so, open up the Support menu in the left hand toolbar of the NexaX window and choose the settings button in the bottom left hand corner of the menu.


Choose the material being used from the drop down menu, and make the changes to the supports using the sliders or text boxes to change in the desired values for each property.


Once the desired changes have been made, scroll all the way to the bottom of the menu and click the apply button to name and save the profile.


When saving the changes users can click Yes to save, No to abort the changes (if saving the profile is not the goal), and Cancel to go back to the custom support menu to continue to make changes.

The custom support profiles can also be managed from the profile library. To access the library, click on the gear icon next to the Setting drop down menu at the top of the Support Settings menu.


This will bring up the profile library. The pencil icon that appears when hovering over each custom profile allows the user to change the name.


Custom profiles can be removed in bulk by checking the boxes that appear next to the custom profile when hovering over the profile. A remove button appears in the top right hand corner of the library window when custom profiles are selected. Click the remove button to delete the selected profiles in bulk.


Click the X in the top right hand corner of the library window to close and return to the Supports Menu. Be sure to click apply in order to save any changes.
