Pac-Dent Rodin Bite Tray
This resin is designed for printing custom full and quadrant maxillary and mandibular arch impression bite trays for use with PVS, VPS, and alginate impression material systems. A robust formulation yields a final product having excellent surface finish, accuracy, and material properties.
Orient the impression trays vertically with tab on platform. This orientation yields the best accuracy, requires the fewest supports and allows the most parts per build.
The Snap To Platform feature enables automatic alignment of a selected surface with the platform. This feature is the best way to quickly and accurately orient the flat side of the tab to the platform.
- Click Orient or Shift + O in the main bar in the printer software.
- Click Select Surface. The button will change to Done.
- Click on the flat underside surface of the part that you want to align with the platform.
- Click on Done to exit Snap To Platform tool.
Supports hold up the part during printing. They do this by connecting platform-facing surfaces to the platform.
- Click Support or Shift + S in the dark gray bar at the top of screen.
- Under Position, select On Platform to lift parts off the platform.
- Under Auto Support Method, select Basic.
- Click Generate to automatically create supports. This may take seconds or minutes depending on the complexity of your part.
Note: We recommend using the Basic support method instead of Advanced for impression trays. The Advanced method’s FEA processing takes about 30 minutes for each tray. Typically, using Basic Auto Supports and manually editing takes 5-20 minutes based on skill level with no drop in part quality.
The Auto-Support function aggressively adds supports to your part in order to ensure print success. Since supports leave small bits or nubs after removal, they reduce part accuracy. Therefore, supports usually need manual editing to eliminate them from important surfaces and features.
- Examine your newly supported model.
- Note any supports that:
- contact any intaglio surface.
- contact any other critical feature.
- Use the Edit feature to remove any unwanted supports.
These are before/after images of the tray before editing and after editing.
Before Editing - Many supports on intaglio surfaces.
After Editing - No supports on intaglio surfaces.
Fences work well for impression trays.
- They are easy to remove.
- They do not increase the footprint of the part, which allows more trays to be built at once.
- Click on Fences.
- Click a series of points on the tray to define the fence.
- Use Overhang Detection to find areas that need support.
- Click Generate to create the fence geometry.
- Repeat as needed.
Carbon recommends running fences every 2 - 4 mm on horizontal or near horizontal surfaces.
This is an example of an impression tray that is well-supported with fences.
- Supported on the platform
- Provides stability.
- Lower than printing above platform so print times are shorter.
- Fewer supports require less resin.
- Intaglio surfaces are free from supports.
Do not change any of the settings under Print Controls. The default settings deliver the best results for impression trays.
- Slice Thickness should stay at Standard (100 µm).
- Reducing the slice thickness by choosing the Fine (50 µm) or Super-fine (25 µm) settings will dramatically 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.
