KeyPrint KeyGuide
Keystone Industries® KeyPrint® KeyGuide™ is now available to produce surgical guides. The material is a rigid, biocompatible resin and is ideal for fast production.
This course will cover the digital prep of your guides to properly prepare them for printing.

Arches and full palates should be rotated 40 degrees with the anterior of the guide rotated away from the platform.
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 model so that the intaglio surface is facing the platform.
4. Adjust the model so that it is mostly parallel with the platform.
5. Rotate the surgical guide so that the anterior is at a 40 degree angle from the platform.
Fence Placement
- Along the guide perimeter.
- Around drill holes.
- On important features such as articulators.
- 2 rows of fences are recommended on features wider than 3 mm.
Fence Free Zones
- Intaglio surfaces
- Interior of drill holes.
- Interior of windows.
- Any critical surfaces.
Before creating supports, check the critical surfaces of your part to ensure that supports will not be needed. Overhang Detection will show surfaces that may need supports by coloring them red.
- Click on the Overhang Detection (V) tool at the bottom of the screen to activate it.
- Leave the default value at 40 degrees.
- Click the Toggle Platform (B) tool to hide the platform for unobstructed viewing of the underside of the model.
- Check critical areas, especially inside drill holes, to make sure those surfaces do not require supports.
- Some intaglio surfaces will be red. But these areas will not require supports.
- If critical areas are red, tilt up the part slightly 1 - 3 degrees and recheck.
- Repeat until critical areas are free of red.
Surgical guides require precise placement of supports. Because of this, we recommend manually adding fence supports.
Fences are ideal for supporting surgical guides of all types (arches, full palettes and quads):
- Easy to remove.
- Contact points are small and require little finishing.
Do not use Automatic supports. This mode will cover a large portion of the intaglio surfaces, which will result in an unusable part.
- Click Support in the dark gray bar at the top of screen.
- Under Position, select Above Platform to lift parts off the platform.
- Under the Manual tab select Fence.
- Click a series of points along the entire perimeter of the arch.
- Carbon recommends using a single, long fence for easier removal.
- A sequence of 2 or more short fences is acceptable.
- Use Overhang Detection to find areas that need support.
- To move points, click Esc key then hold down E key. Click on a point and move it to a new location.
- Repeat as needed to add additional fences.
- Click Generate to create the fence geometry.
Continue adding fence supports to these features:
- bars
- wide areas (offset from perimeter fence by 2 - 4 mm)
- articulators
- any other critical features.
Ensure that the following surfaces are free from fences:
- Intaglio surfaces
- Interior of drill holes
- Interior of windows
- Any critical surfaces
Either end (posterior or anterior) of the quad should be rotated 40 degrees off of the platform.
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 quad so that the intaglio surface is facing the platform.
4. Adjust the quad so that it is mostly parallel with the platform.
5. Make sure that the quad is parallel with the left/right sides of the platform.
6. Rotate the quad so that it is at a 40 degree angle from the platform.
Either the anterior or posterior of the quad can be rotated off of the platform.
Before creating supports, check the critical surfaces of your part to ensure that supports will not be needed. Overhang Detection will show surfaces that may need supports by coloring them red.
1. Support entire perimeter of quad with fence supports.
- We recommend using a single, long fence for easier removal.
- A sequence of 2 or more short fences is acceptable.
2. Create secondary lines of fences on wide areas.
- Offset from perimeter fence by 2-4 mm where possible.
3. Support other critical features.
Ensure that the following surfaces are free from fences:
- intaglio surfaces
- interior of drill holes
- interior of windows
- any critical surfaces
- Intaglio surfaces facing platform.
- Supported above platform.
- Fences around part boundary.
Arch/Full Palate
Rotated 40 degrees with posterior tilted towards platform.
Quad
Rotated 40 degrees with either anterior or posterior tilted towards platform.
Click Print Controls or Shift + P in the top menu bar.
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.
- Select the Project Analysis tab.
- Click Start Analysis and wait for the processing to complete.
- Note the required resin volume and print time.
- Click Add to Queue.
