Trivest CAM - Instructions for Use with exocad design settings.

Your complete digital workflow for refractory dies starts here.  

TriVest Workflow Steps After you finish your design:

1. Design the digital die model without undercuts for 3D printing. 
2. Place your dies in your CAM software and create at least 3 connectors per die.
3. You can mill Trivest CAM ¨wet¨ or ¨dry¨ with a 1-1 ratio (there is no shrinkage factor).
4. Use your same diamond coated milling burrs that you use with Zirconia.  
5. For the "feed-speed" setting, you may want to choose a "soft" or "slow" setting.  
6. Use your same milling strategy as you do with Zirconia. You can use Composite strategy as an alternative. 
7. Once the milling process is done, cut the dies, smooth the connectors, and place the dies in the model.  If your die doesn't fully seat, you may need to adjust the anti rotation rim. 
8. The recommended CTE for your porcelain layering is between 9-14
9. You don´t need to do a degas firing; we did it for you. Start your wash firing and continue with your ceramic layering as usual with TriVest CAM die.
10. To detach the veneer from the die, sandblast with glass beads.

FAQ

1. What if my CAM software does not allow a 0% enlargement with Zirconia milling strategy?
   • Some CAM software does not allow zirconia milling strategy to be set to 0% enlargement factor.  If this happens, you may use another 1-1 milling strategy with the same "speed and feed" rate as zirconia and the same diamond coated tools as zirconia.  Some customers have used a PMMA milling strategy with new diamond coated burs and found success.
