### Create Project
::::VerticalSplit{layout="left"}
:::VerticalSplitItem
After you have chosen the printer, you must create a new project.
:::
:::VerticalSplitItem

:::::WorkflowBlock
:::WorkflowBlockItem
Click **New Project.**
You can also drag your files from a file browser window and drop it on top of the **New Project** icon.
:::
:::WorkflowBlockItem
Enter a new **Project name.**
:::
:::WorkflowBlockItem
In the Resin dropdown, select **your resin.**
:::
::::WorkflowBlockItem
Only use [Encrypt project](docId:1bT3mas8msvxq9CDza67C) if you want to require a password to access the project.
:::hint{type="warning"}
**Carbon cannot provide support** for encrypted projects.
:::
::::
:::WorkflowBlockItem
**Drag and drop** your part files into the dotted box or click **browse your files **and select them in a file browser window.
:::
:::WorkflowBlockItem
Click **Create**
After a few moments you will see the project printer interface with your parts on the platform.

## Orientation
:::hint{type="info"}
For detailed information about orienting parts, read [Orient](docId\:rMnxtq1NIAHXZOc4bZXWu).
:::
- Orient the teeth so that the **intaglio surface is facing away from the platform.**
- Adjust the teeth so that they are **mostly parallel with the platform**.
## Supporting
:::hint{type="info"}
See [Supports](docId\:VUbpoAitbLM11aM9-qJ1p) for detailed information.
:::
::::WorkflowBlock
:::WorkflowBlockItem
Select the [Supports](docId\:VUbpoAitbLM11aM9-qJ1p) tab in the top bar or press **Shift + S.**
:::
:::WorkflowBlockItem
In the bottom bar, toggle [Overhang Detection](docId:1bT3mas8msvxq9CDza67C) **on.**
::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/v1741914659/Education/Materials/dental/__General_Use/overhang-detection02.gif" size="70" width="712" height="278" position="flex-start" showCaption="false"}
:::
:::WorkflowBlockItem
Also in the bottom bar, set [Toggle Platform](docId:1bT3mas8msvxq9CDza67C) to **off.**
::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/v1741970064/Education/Materials/dental/__General_Use/toggle-platform02.gif" size="70" width="722" height="347" position="flex-start" showCaption="false"}
:::
:::WorkflowBlockItem
Set **Part Postion** to **Above.**
::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/v1743201611/Education/Materials/dental/__General_Use/part-position-above.jpg" size="50" width="733" height="146" position="flex-start" showCaption="false"}
:::
:::WorkflowBlockItem
Select the [Patch ](docId\:VUbpoAitbLM11aM9-qJ1p) tool and determine settings.
A. Click the **Patch **tool.
B. Click on an area of overhang to create a patch. Additional controls will appear in the Support menu below Patch.
C. Adjust the **Overhang **slider.
- For posterior teeth, the default **40 degrees** is typically sufficient.
- For anterior teeth, a higher value of **40 - 50 degrees** may be needed.
D. Under Primary Support Type, select **Fence. **Leave Spacing at **5 mm.**
::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/v1743211488/Education/Materials/dental/SprintRay-Apex-Teeth/ui-supports-primary-support-type.png" size="70" width="307" height="206" position="flex-start" showCaption="false"}
D. Scroll down and make sure **Boundary Fence** is selected and set to **0 mm.**

:::
:::WorkflowBlockItem
Support overhangs with [patches](docId\:VUbpoAitbLM11aM9-qJ1p).
- Continue clicking to create patches until all overhangs are selected.
- Click Generate to create the supporting fences.
- Avoid adding supports to **intaglio surfaces.**
:::
:::WorkflowBlockItem
Check supports.
- Make sure all overhangs are supported.
- Delete supports on intaglio surfaces.
- Adjust **Overhang **slider if necessary to create larger/smaller patches.
:::
::::
## Nesting
::::WorkflowBlock
:::WorkflowBlockItem
Select the **Layout tab (Shift + L)** in the top menu bar.
:::
:::WorkflowBlockItem
Under **Auto Layout,** select **Gen2.**
Gen2 usually gives the most efficient packing for dental devices.
:::
:::WorkflowBlockItem
Enter at least **1 mm** in **Padding.**
Models require a minimum of 1 mm of space between them.
:::
:::WorkflowBlockItem
Leave **Optimize starting rotation** unchecked.
This leaves your parts in their previous orientations.
:::
:::WorkflowBlockItem
Leave **Allowed rotations** at the default setting.
This gives the software maximum flexibility to fit the most possible parts on the build platform.
:::
:::WorkflowBlockItem
Press the **Auto Layout** button to arrange your parts.
:::
::::
If necessary, nesting can be changed manually:
- Click and drag parts to adjust their position.
- Modify Z rotation by using the **Spin **tool or manual rotations under the **Orient tab** **(Shift + O).**
- Use the [Part List tab](docId:1bT3mas8msvxq9CDza67C)** **as needed to more easily select models and focus on them.
## Print Controls
Click **Print Controls** or **Shift + P** in the top menu bar.
### Slicing
::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
Set Slice Thickness to **Standard (100 µm).**
:::
:::VerticalSplitItem
:::
::::
:::hint{type="warning"}
Reducing the slice thickness by choosing the Fine (50 µm) or Super-fine (25 µm) settings will increase print time and may reduce part quality and accuracy.
:::
## Project Analysis
::::WorkflowBlock
:::WorkflowBlockItem
On the top menu bar, select the **Project Analysis tab** (Shift + A).
:::
:::WorkflowBlockItem
Press **Start Analysis.**
:::
:::WorkflowBlockItem
After a short time, the result of the project analysis will be displayed. Note the **print time** and the **required resin volume.**
