General Orientation & Support Information





Use Patch and Fence tools to create supports




Review Supports in Printer UI course for more information.



Orienting

Because try-ins are organic surfaces with no well-defined flat areas, we do not recommend using Snap To Platform.



Proper orientation of denture try-ins is critical to achieving the required accuracy, detail, and surface quality.

Try-ins should be oriented at 90 degrees to the platform with the anterior facing the platform.

Workflow

1. Click on Orient or Shift + O in the top bar in the printer interface.

2. In the lower right corner of the bottom bar, turn on Overhang Detection or V key and set to 40 degrees. Areas that need support will appear red.

3. Orient the try-in so it is about parallel to the platform.

4. Rotate the models 90 degrees with the anterior facing the platform. The model should be standing vertically, perpendicular to the platform.

Supporting

Users can support denture try-ins with patches, fences or a combination of the two. Carbon encourages you to experiment with both and use what works best for your geometries and workflow.

Patch Support Workflow

Enter Support Mode and Select Patch

Do not use Automatic supports. This mode will cover a large portion of the intaglio surfaces, which will result in an unusable part.



  1. Click Support (or press Shift + S) in the dark gray bar at the top of screen.
  2. Under Position, select Above Platform to lift parts off the platform.
  3. Under the Manual tab select Patch.

Patch Settings

  1. Click on an area needing support (shown in red by the overhang detection tool). The area will turn green once selected and the Patch settings will appear.
  2. In the settings, increase the Overhang to 50º.
  3. Select Fence from the Primary Support Type drop-down
  4. Check the Boundary Fence box.

Leave all other settings at their defaults.

Add Patch Supports

  1. Click on all additional areas requiring support. Previously selected areas will turn purple.
  2. Click Generate All.
  3. Confirm that adequate supports have been created.

Fence Support Workflow

Fences are ideal for supporting model walls that face the platform.

  • Easy to remove.
  • Contact points require less finishing.



Do not use Automatic supports. This mode will cover a large portion of the intaglio surfaces, which will result in an unusable part.



Enter Support Mode and Select Fence

  1. Click Support (or press Shift + S) in the dark gray bar at the top of screen.
  2. Under Position, select Above Platform to lift parts off the platform.
  3. Under the Manual tab select Fence.

Add Fence Supports

  1. Click on Fences.
  2. Click a series of points on the model to define the fence.
    • Use 40º Overhang Detection to find areas that need support.
    • Fences are only required at the edges.
  3. Click ESC key and then hold down E key to reposition points.
  4. The Support Attributes may be left in the default settings.
  5. Click GENERATE ALL to create the fence geometry.
  6. Repeat as needed.

Nesting



Print Preparation

Print Controls

Click Print Controls or Shift + P in the top menu bar.

Slicing

  • Slice Thickness should be Standard (100 µ).
  • Reducing the slice thickness by choosing the Fine (50 µ) or Super-fine (25 µ) settings will increase print time and may reduce part quality and accuracy.
