Disclaimers
Dreve FotoDent® IBT for Carbon printers is a product of Dreve Dentamid GmbH.
Because this resin is not manufactured by Carbon, the following disclaimer applies to Dreve’s resin including mechanical properties, handling, printing, washing and curing. It does not apply to Carbon’s hardware, software or accessories.

Dreve FotoDent® IBT for Carbon printers has been developed specifically for use as a dental device. All of the content herein is written to produce dental devices.
All validation of material properties, orientation & support strategy, print settings, washing and curing procedures was performed using indirect bonding tray geometries on a standard cassette using manual (non-Smart Part Washer) washing and a Dreve PCU LED UV curing device.
Usage of this material outside of these conditions will result in limited Carbon support.
Contact Carbon for more information.
Dreve FotoDent® IBT for Carbon printers is now available to produce indirect bonding trays. The material is a clear, biocompatible resin and is ideal for fast production.
This guide will cover digital pre-processing of your IBT devices to properly prepare them for printing with FotoDent® IBT for Carbon printers.
Carbon strongly recommends creating devices with flat occlusal planes. This maximizes yield while minimizing printing and post-processing times.
Please follow these recommendations when designing indirect bonding trays.
- Flat and featureless occlusal plane.
- Creates a strong tray.
- Minimizes part failure due to adhesion issues.
- Minimum wall thickness of 1 mm for optimal print outcomes.
- Prevents breaking.
- Minimize part height.
- Conserves resin.
- Minimizes print time.
- Parts should be solid.
- Avoids potential venting issues during printing that can lead to failure.
Proper orientation of indirect bonding trays is critical.
- Maximizes yield by minimizing print defects.
- Eliminates the need for supports and the accompanying labor and resin costs.
- Achieves the required accuracy and surface quality.
All indirect bonding trays should be oriented to be flat against the build platform.
Orienting Parts With Flat Occlusal Plane
Use Snap to Platform to ensure the flat base is aligned with the platform.
- Click on Orient in the main bar in the printer software.
- Select the part to be oriented.
- Under Snap to Platform click the Select Surface button.
- Click anywhere on the flat base of the tray part. The printer software will automatically rotate the part base to be parallel with the platform.
Note: Carbon recommends using Snap to Platform on all parts to ensure the part base is flat against the platform. Even a small angle between the part and the platform may result in a failed print.
Supports
Indirect bonding tray parts with a flat occlusal plane do not require supports because they print directly on the platform.
Z Rotation Of Tray Parts
As long as the base of the part is snapped to the platform, you have freedom to rotate the part in the Z axis to suit your needs.
Properly Oriented And Supported IBT Part
Flat Occlusal Plane
- All indirect bonding trays should be oriented to be flat against the build platform.
- Any orientation is acceptable.
Design Recommendations
Carbon strongly recommends creating devices with flat occlusal planes. However, if this is not possible, conformal occlusal planes may be used.
Be aware that conformal occlusal plane devices have the following effects:
- Part must be printed at angle relative to platform.
- Support structures are required.
- 2-3x increase in print time relative to flat occlusal plane.
- Post-processing time increases due to support removal.
- Minimum wall thickness of 1 mm for optimal print outcomes.
- Prevents breaking.
Proper Orientation Of Parts
Proper orientation of indirect bonding trays is critical.
- Maximizes yield by minimizing print defects.
- Achieves the required accuracy and surface quality.
45 degree orientation with anterior teeth facing away from platform.
Intaglio surface facing platform.
Orienting Parts With Conformal Occlusal Plane
Perform an initial orientation of both bases so that they are roughly parallel with the platform.
- Click on Orient in the main bar in the printer software.
- Orient each base so that the intaglio surface is facing the platform.
- Adjust the trays so that they are mostly parallel with the platform.
- We recommend typing values into the XYZ axis fields. Changing orientation with the mouse or Snap to Platform function is more challenging.
- Position the camera so you are looking straight down on the platform:
- Push the Reset camera icon in the lower left corner of the screen to return to the default view.
- Push ▲ to look straight down at platform.
- Make sure that the posterior region of the tray is facing the lower portion of the screen.
Final Orientation
Now perform the final orientations. Because indirect bonding trays with conformal occlusal planes are organic surfaces with no well defined flat areas, we do not recommend using Snap To Platform. It is much easier to enter values directly into the Orient fields.
- Click on the part to select it.
- Enter a value of 45 degrees into the X Axis field.
- The posterior of the part should be touching the platform.
Supports
Supports hold up the part during printing. They do this by connecting down-facing surfaces to the platform. Carbon recommends using Fences. They are easy to remove and do not increase the footprint of the part, enabling more parts to be fit onto the build platform.
- Click Support in the main bar in the printer software.
- Under Position, select Above Platform to create room between the platform and the part.
- Skip Auto Support Method as this mode is not recommended.
Add Fences
You will now see the support editing view. Support the entire perimeter of the intaglio walls.
- Click Toggle Platform button in the lower tool bar to hide the platform. This will enable better visibility during fence creation.
- Click the fence icon in the top menu bar.
- Click a series of points on the base to define the fence.
- Use Overhang Detection to find areas that need support.
- Carbon recommends making a series of small fences rather than making a single continuous fence to give greater flexibility to reposition points.
- Click ESC key and then hold down E key to reposition points.
- Click Generate to create the fence geometry. This may take a few minutes.
Z Rotation Of Tray Parts
You have freedom to rotate the part in the Z axis to suit your needs.
Conformal Occlusal Plane
- 45 degree orientation with anterior teeth facing away from platform.
- Intaglio surface facing platform.
- Any orientation is acceptable.
Once parts have been properly oriented and/or supported they should be nested for printing.
- Select the Layout tool in the menu bar of the printer software.
- Enter at least 1 mm in Padding in mm.
- Parts require a minimum of 1 mm of space between them.
- Check Overlap bounding boxes.
- This gives the software maximum flexibility to fit the most possible parts on the build platform.
- Press Auto Layout button to arrange your parts.
Print Controls For IBTs
Click Print Controls in the menu bar of the printer software.
Slicing
- Slice Thickness should be Standard (100 µ) setting.
- 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.
