Desktop Health Flexcera Smile and Flexcera Smile Ultra+
Flexcera™ Smile and Flexcera™ Smile Ultra+ are now available for Carbon M- Series printers to produce artificial teeth for dental prostheses, which are one of the main components in the fabrication of removable permanent full dentures.
This guide will cover the orientation and supporting of the digital models for the applications listed above

This protocol sheet applies to both Flexcera Smile and Flexcera Smile Ultra+.
Flexcera™ Smile may only be used for the production of artificial teeth for dental protheses, which are one of the main components in the fabrication of removable permanent full dentures. Any deviation from the Instructions for Use can negatively affect the chemical and physical properties of the finished product. Consequently, the biocompatibility of the full denture cannot be guaranteed.
Flexcera™ Smile may not be used for the production of e.g. crowns, bridges, veneers, cover dentures, implant retained full or partial dentures or any other application which deviates from the indication.
For design recommendations, see manufacturer instructions for use here.
Carbon has validated four shades of Flexcera Smile/Flexcera Smile Ultra+ resins: Bleach, A1, A2 and B1. There are two options in the printer UI resin menu:
- Flexcera Smile/Flexcera Smile Ultra+ Bleach for use with the Bleach shade.
- Flexcera Smile/Flexcera Smile Ultra+ A1, A2, B1 for use with A1, A2 or B1 shades.

- 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.

Continued from Patch workflow above. So be sure the part is selected and overhangs are clearly visible.
- 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.

- Digital models should be oriented with the occlusal surfaces facing the platform.
- Does not apply to try-ins or full-arch denture teeth.
- Necessary to maintain accuracy.
- Ensures supports are on the occlusal surfaces enabling greater accuracy for mating surfac

Orient parts so that interfaces and margins are free from overhangs so that no supports are required there. Supports leave nubs which require more finishing and can affect fit with mating parts or teeth.

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

When printing crown and bridge geometries in Flexcera Smile/Flexcera Smile Ultra+, use the print profile Flexcera Smile Ultra+ C&B.
- The use of this print profile will improve the accuracy of the intaglio surfaces of these types of geometries, but will also increase the print time.
- Do not use this print profile when printing denture teeth or monolithic dentures in Flexcera Smile/Flexcera Smile Ultra+.
- If you do not see the Flexcera Smile Ultra+ C&B print profile in your print controls, please contact Carbon Support.
- There are two options for Print Profile:
- When printing crown and bridge geometries select Flexcera Smile Ultra+ C&B.
- For denture teeth, monolithic dentures and veneers, use the Default profile.
- Under Slicing, select either Standard (100 µm) or Fine (50 µm), depending on your preference.
- Leave all other values at their default values.

NOTE: Fine (50 µm) slice thickness will result in increased print times compared to Standard (100 µm).
Application | Print Profile | Slicing |
---|---|---|
Denture Teeth or Monolithic Denture | Default | Standard (100 µm) or Fine (50 µm) |
Crown or Bridge | Flexcera Smile Ultra+ C&B | |
Veneer | Default |
- Select the Project Analysis tab.
- Click Start Analysis and wait for the processing to complete.
