General Orientation & Support Information
Hide the Platform
Use Toggle platform (or press B) to hide the platform before orienting parts. This will make it easier to see overhangs and place supports.
Patch and Fence tools
Patch tool
- The Patch tool speeds up support creation by automatically supporting an area with just a few clicks. It is useful for supporting larger areas of overhang that would take longer to support manually.
- It is often useful to support your parts with this tool before manually adding supports.
Fence tool
- Fence supports are manually placed by the user and are best suited on linear overhangs or smaller areas.
- Fences provide stability while leaving smaller nubs than the default Bars option.
Review Supports in Printer UI course for more information.
Orientation Options
There are 2 options for orienting bases for printing.
Near Horizontal
- No supports on cameo surface
- Limits supports on intaglio edge
- Minimizes support creation and support removal time
- Minimizes print time
- Fewer models per print
Near Vertical
- No supports on intaglio surface
- Requires more time creating and removing supports
- Requires more finishing time to remove support nubs
- Increase print time
- More models per print
Orient & Support Near Horizontal
Initial Orientation
Perform an initial orientation of both bases so that they are roughly parallel with the platform.
- Click on Orient or Shift + O in the main bar in the printer software.
- In the lower right corner, turn on Overhang Detection or V key set to 40 degrees to indicate areas that need support in red.
3. Orient each base so that the tissue-facing surface is facing the platform. 4. Adjust the bases so that the tooth sockets are mostly parallel with the platform.
5. Position the camera so you are looking straight down on the platfrom. Make sure that the posterior region of each base is facing the lower portion of the screen.
Final Orientation
Now perform the final orientations. Because denture bases are organic surfaces with no well defined flat areas, we do not recommend using Snap To Platform.
Maxillary Base
- Click on the maxillary base to select it.
- Enter 30 into the X axis field.
- The posterior of the base should be touching the platform.
Mandibular Base
- Click on the mandibular base to select it.
- Enter -15 into the X axis field.
- The anterior of the base should be touching the platform.
Supporting
- Click Support or Shift + S in the dark gray bar.
- Under Position, select Above Platform to lift parts off the platform.
- Skip Auto Support Method as this mode is not recommended.
- Click Manually Add to go to the Support editing interface.
Using either Auto Support method will result in supports covering a large portion of the tissue-facing surfaces, which will use more resin and require more cleanup.
Add Fence Supports
Fence supports are required to support the edges of mandibular and maxillary bases.
- Click on Fences.
- Click a series of points in an area of overhang to define the fence.
- Use Overhang Detection to find areas that need support.
- 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.
- Repeat as needed.
Supporting Maxillary Base
Fence Supports
- Support entire boundary of base with fence supports.
- We recommend using a single, long fence for easier removal.
- A sequence of 2 or more short fences is acceptable.
Once the outer boundary of the maxillary base has been supported with fences, proceed to supporting the palette with bar supports.
Supporting Maxillary Base Palette
Support the palette with a field of bar supports to prevent deformation.
Bar Supports
- Press Overhang Detection to highlight the areas to focus on.
- Click on Multiple add.
- Click in the palette area to create field of points that will be contact points for bar supports.
- Bar supports are usually required only in the palette area.
- Place points within 3-6 mm of each other.
- Click Generate to create the bar supports.
- Check the bar supports and move to supporting the mandibular base.
Supporting Mandibular Base
Use fences to support the outer boundary of the base. Mandibular bases also require additional fences in the posterior areas to ensure proper fit.
- Support entire boundary of base with fence supports.
- We recommend using a single, long fence for easier removal.
- A sequence of 2 or more short fences is acceptable.
- Create secondary lines of fences along the posterior region.
- Offset from outer fence by 2-4 mm.
Examples of Properly Oriented and Supported Bases
- Tissue-facing surfaces facing platform.
- Supported Above Platform.
- Fences around part boundary.
- Bar supports on maxillary base palette.
Maxillary Base
Rotated 30 degrees with posterior tilted towards platform.
Mandibular Base
Rotated 15 degrees with anterior tilted towards platform.
Orient & Support Near Vertical
Orienting your denture base models vertically keeps the intaglio surface free of supports and allows more models to be fit on the build platform at the expense of increased printing time and additional time required to create supports and then remove them after printing.
Initial Orientation
Perform an initial orientation of both bases so that they are roughly parallel with the platform.
- Click on Orient or Shift + O in the main bar in the printer software.
- In the lower right corner, turn on Overhang Detection or V key set to 40 degrees to indicate areas that need support in red.
3. Orient each base so that the tissue-facing surface is facing the platform. 4. Adjust the bases so that the tooth sockets are mostly parallel with the platform.
5. Position the camera so you are looking straight down on the platfrom. Make sure that the posterior region of each base is facing the lower portion of the screen.
Final Orientation
Now perform the final orientations. Because denture bases 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.
Maxillary and Mandibular Bases
- Click on the base model to select it.
- Enter -95 into the X axis field.
- The labial surface of the bases should be facing the platform.
- The lingual surfaces should be 5-10 degrees from vertical, tilted towards the platform.
Supporting
- Click Support or Shift + S in the dark gray bar.
- Under Position, select Above Platform to lift parts off the platform.
- Skip Auto Support Method as this mode is not recommended.
- Click Manually Add to go to the Support editing interface.
Using either Auto Support method will result in supports covering a large portion of the tissue-facing surfaces, which will use more resin and require more cleanup.
Support Papillas
Use bar supports to support papillas.
- Click on Bar support button.
- Click on each papilla to place a single support.
- Click Generate to create the bar supports.
- Repeat as needed.
Support Lingual Walls
- Click on Bar support button.
- Use Overhang Detection to find areas that need support.
- Click a series of points to support lingual walls.
- Click Generate to create the bar supports.
- Repeat as needed.
Support Labial Walls
Fences are ideal for supporting base walls that face the platform.
- They are easy to remove.
- Contact points require less finishing.
- Click on Fences.
- Use Overhang Detection to find areas that need support.
- Click a series of points to define the fence.
- Click ESC key and then hold down E key to reposition points.
- Click Generate to create the bar supports.
- Repeat as needed.
Support Tooth Channels
- Click on Bar support button.
- Click a series of points to support the tooth channels of the few teeth that are closest to the platform.
- Click Generate to create the bar supports.
- Repeat as needed.
Examples of Properly Oriented and Supported Bases
- Bases oriented vertically, tilted 5-10 degrees towards platform.
- Papilla, lingual walls and tooth channels supported.
- Support-free intaglio surface.
- Labial wall supported with fence.
Nesting
- Select the Layout tab (Shift + L) in the top menu bar.
- Under Auto Layout, select Gen2.
- Gen2 usually gives the most effecient packing for dental devices.
- Enter at least 1 mm in Padding.
- Models require a minimum of 1 mm of space between them.
- Leave Optimize starting rotation unchecked.
- This leaves your parts in their previous orientations.
- Leave Allowed rotations at the default setting.
- This gives the software maximum flexibility to fit the most possible parts on the build platform.
- 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 as needed to more easily select models and focus on them.
Print Preparation
Print Controls
Click Print Controls or Shift + P in the top menu bar.
Do not change any of the settings under Print Controls. The default settings deliver the best results for denture bases.
Slicing
Slice Thickness should stay at the 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.
Project Analysis
- Select the Project Analysis tab.
- Click Start Analysis and wait for the processing to complete.
- Note the required resin volume and print time.
