Project UI
The project page is where you set up your parts for printing.

1
The first step in starting a project is to select a resin.

2
The part list shows all parts in the project and provides functionality options to manage your parts, inlcuding download options.

Downloading Individual Parts
You can download individual parts and their corresponding supports. Note that supports are merged with the part and will no longer be editable when imported into another project.
Downloading Parts with supports
Additional guidance is provided when downloading parts with supports and/or labels to avoid confusion about how these features are handled in downloaded STLs

Turn on Overhang detection
Set to the recommended unsupported angle for the resin
Adjust view to assess orientation
💡 Adjust the orientation to minimize overhang areas
Select Measure
Measure the largest overhang(s) to see if they fall below the recommended maximum for the resin
This overhang falls below the maximum recommended for the resin.
This part does not require supports for overhangs in this orientation, but it does need supports for three other reasons.
Adhesion
Island
Stability
Overhang detection provides a gradient color range to provide guidance on where to place supports. The color range is anchored around the recommended unsupported angle for the resin in the 30-40° range.
Click on the ? Help icon in the software for Range Information while working. Click on the icons below for more information and guidance on what each color means in practice.

1
Dark red areas require supports with a dense spacing, matching the maximum recommended overhang for the resin (ie use a 2 mm spacing for RPU 70).
If the combined red area (essential and recommended) measures smaller than the recommended overhang, supports may not be required. (Stability or adhesion supports may still be needed.)
2
To maintain accuracy, supports should also be applied to the lighter red area, but you can use a moderate spacing of approximately twice the recommended overhang (ie start with a 4 mm spacing for RPU 70).
If the combined red area (essential and recommended) measures smaller than the recommended overhang, supports may not be required. (Stability or adhesion supports may still be needed.)
3
This is the recommended minimum unsupported angle for the resin.
You may choose to include supports in the orange area if you have a tight tolerance on a feature.
Spacing can be sparse at approximately triple the recommended overhang (ie start with a 6 mm spacing for RPU 70).
You may choose to NOT use supports in the orange area if post-processing is limiting production capacity and you want to push the limits on your use of supports.
4
Additional supports are recommended in the following conditions to withstand printing forces. Spacing is less of a guideline here as the main factors to consider are resin and orientation.
Softer resins such as the EPU family will require more stability.
Orientations where the center of gravity is both far from the platform and far from the adhesion area require more stability*.
Start at a moderate spacing and iterate as needed.
*Stability supports may be needed outside of yellow overhang areas as well, depending on the orientation. The yellow areas simply indicate an area where supplemental supports are advised in unstable conditions.
5
No supports needed.
This RPU 70 part has an 8.5 mm hole.
Measuring half of the total detected overhang (half because this overhang is a bridge), we measure over 2 mm, which exceeds the recommended overhang for RPU 70.
However, if we measure just the red areas (essential and recommended), the measurement falls below the recommended overhang.
This hole will print fine without supports. Optionally, you could add supports if the hole requires an especially tight tolerance, but in most conditions that will not be necessary.

Keyboard Shortcuts
In addition to referencing shortcuts in the software, you can also download this comprehensive handout.
Users have the option to preserve original model positions upon uploading part models.
Standard Formation Without Preserving Model Position
When importing multiple models, standard behavior will place models as close to the center of the platform as possible, without overlapping.
Preserving Model Position
When a new project is created, you can opt to preserve the original model positions from design software (XYZ coordinates). This may be useful if you have set relative positions of parts in design software and wish to retain those positions on the print platform.
To enable this function, check Preserve original model positions in the project creation dialog. Leaving this box unchecked will place part(s) in the standard formation.

Regardless of what is selected at project creation, any parts uploaded to the project at a later time will not retain XYZ coordinates and instead will be placed per standard formation.

Z Position
If part models are built in negative Z space, the models are raised up to the platform at Z = 0.
Negative Z positions are raised up to the platform (Z = 0)

Note that parts created above Z = 0 will be imported above the platform.
You may move parts in Z in the Layout tab after import as needed.
This feature is therefore not recommended for dental applications that may have parts inadvertently placed above the platform due to their design workflow.
Exception for dental applications using the AO-Stack workflow.

Check Build After Correction Scale
Resin- and part-specific correction scale may adversely impact intentional model positions.
If precise spacing is needed or if parts end up too close together for successful printing:
Reference the correction scale factor for each part
Pre-scale parts in design software per referenced scale factor and adjust model positions as needed
Upon importing scale-corrected parts, change the correction scale to 1:1:1 (to avoid scaling them twice)

Note that each part may have different correction scale factors if they have different geometries.
Model Security
Next-Generation Architecture


Carbon uses a hybrid architecture with significant computational power in each machine, a browser-based user interface, and secure connectivity to the Carbon Cloud @ AWS.
Security Model
Digital models are stored on the printer, behind a customer firewall, optionally encrypted
An outbound secure, encrypted tunnel connects to the Carbon Cloud
Although the printer software is cloud-based, losing internet connectivity will not affect any in-progress prints.
Optional Encryption
The digital models stored on the printer may optionally be encrypted for additional security.
You must opt in to use the encryption feature on a per printer basis.
Contact your Carbon account manager for details.

How It Works
Set a password at project creation
Enter the password each time you access the project
What You Can Do
Enable encryption on a per printer basis through your account manager
Choose on a per project basis when to use the encryption feature

What You Can NOT Do
Carbon cannot provide support on encrypted projects
Carbon cannot help you recover the password or the project file if forgotten or deleted respectively
Slice videos are not available for any encrypted projects

Sharing Models with Carbon
If you would like to consult with Carbon Support, it’s easy to share a print through Carbon’s Printer UI. This will enable the Carbon team to tailor their advice to your particular part and the goals for your production run. Carbon will use information about your part for the sole purpose of helping to get the best part from your Carbon printers.
There are 3 methods available to share your model with Carbon Support and request help.
