General Orientation & Support Information
Hide the Platform
Use Toggle platform (or press B) to hide the platform before orienting parts. This will make it easier to see overhangs and place supports.

Use Patch and Fence tools to create supports
Patch tool
- The Patch tool speeds up support creation by automatically supporting an area with just a few clicks. It is useful for supporting larger areas of overhang that would take longer to support manually.
- It is often useful to support your parts with this tool before manually adding supports.


Fence tool
- Fence supports are manually placed by the user and are best suited on linear overhangs or smaller areas.
- Fences provide stability while leaving smaller nubs than the default Bars option.


Support Creation Workflows
Enter Support mode
- Click Support tab or Shift + S in the top bar.
- Select the part you want to support.
- Under Position, select Above Platform to lift parts off the platform.

Patch workflow
- Select the part to be supported.
- Orient the camera so that the overhangs are clearly visible.
- Check that Patch is selected.
- Click on each large overhang to select it. A green patch will appear over each overhang. Repeat until all the large overhangs are selected.
- Under Support Attributes → Primary Support Type, select Fence.
- The other Support Attributes should remain their default values.
- Click Generate All to create the support fences.
Fence workflow
- Select Fence tool.
- Click a series of points in an area of overhang to define the fence.
- Target long, narrow overhangs and small overhangs.
- Click ESC key to finish adding points to a polyline.
- Hold down E key to reposition points.
- Click off of the part and drag a box to select points. Press Backspace to delete.
- Click a polyline to select for editing.
- Support Attributes should remain their default values.
- Click Generate All to create the support fences.
- Repeat steps 1 - 5 as needed.
- Alternately, you can add multiple polylines as needed and then click Generate All to create multiple fences at once.

Manual Support
Support Strategy

Denture bases are supported using two tools:
- The Patch tool automatically creates a field of supports. It is used to create supports for the anterior facial region.
- The Fence tool is used to manually place a thin wall of supports. Fences are placed along the lingual and buccal edges for lower dentures and along lingual edges on upper dentures. In some cases, fences are needed on T-bars or the posterior edges of upper dentures.
Note: Do not put supports on intaglio surfaces.
Support Setup
Before starting, optimize the interface for adding fences.
- Click Toggle Platform button in the lower tool bar or press the B key to hide the platform. This will enable better visibility during fence creation.

- Click Overhang Detection button (V key) to find areas that need support.
- Set the angle to 40-60 degrees.

Enter Support Mode

- Click Supports in the dark gray bar.
- Under Part Position, select Above to create room between the platform and the part.
- Click the Manual tab and select Patch.
- Leave the Support Attributes at the default values.
Support Denture
Support Anterior Area and edges with Patch Supports
The outer anterior area is typically a large overhang that requires dense fence supports. This area must be supported with the Patch support tool. This is required for both upper and lower dentures. The example pictured is an upper denture.
- While in the Supports menu, click the Manual tab and select Patch.
- Click in the large overhang on the anterior of the upper base. A green patch will appear.
- Under Support Attributes click Primary Support Type and select Fence.
- In the Spacing box, spalce supports between 3-5 mm.
- Scroll down to the bottom of the Supports menu and turn Boundary Fence on.
- Adjust the Overhang slider untile the highlighted overhang areas are covered by the green patch. Typically this will be between 40 and 60 degrees.
- Click Generate all.

See a demonstration of using the Patch tool in the video below.

Inner edge of lower denture
The inner edge of the lower denture requires manual fence supports:
- Click a series of points along the edge to define the fence.
- Click Esc key on the keyboard to end a fence and begin another.
- Hold down the E key and click with the mouse to reposition points.
- Click Generate All to create the fence geometry. This may take a few minutes.
Be sure to set Part Position to ABOVE before you begin adding supports.
Error: Support couldn't be added
Sometimes an error will occur when you try to generate a new fence.
If this happens the points will turn pink and an error messsage will appear.
Try making multiple shorter fences or try adding the fence in a slightly different place.


Posterior edge of upper denture
Although upper dentures do not have an inner edge, they may require supports along the posterior edge to ensure proper accuracy.
Lower denture T-bars
- Click a series of points along the bottom surface of the T-bars to define the fence.
- Click Esc key on the keyboard to end a fence and begin another.
- Hold down the E key and click with the mouse to reposition points.
- Click Generate All to create the fence geometry. This may take a few minutes.

Nesting
Once full or partial dentures have been properly oriented and supported, they should be nested for printing.
- Select the Layout tool in the top menu bar.
- Under Auto Layout select Gen1 or Gen2.
- Gen1 is Carbon's standard tool
- Gen2 is Carbon's more recent algorithm that can improve nesting performance.
- Enter 5 mm in Padding. Values as low as 1-2 mm can also be used.
- For Gen1 auto layout, check Overlap bounding boxes. This gives the software maximum flexibility to fit the most possible parts on the build platform.
- For Gen2 auto layout, 3 options are available for part rotation: Default (0°, 90°, 180°, 270°), Limited (0°, 180°), Do not rotate (0°).
- Press the Auto Layout button to automatically nest the dentures.

If necessary, nesting can be changed manually:
- Click and drag parts to adjust their position.
- Modify Z rotation by using the Spin tool or by selecting the Orient button in the main menu bar and using the Z axis loop.
- Use the Part List tab as needed to more easily select models and focus on them.
The video below shows the process described above.
