- Create a new case, set the Object type to Digital Impression. Select the unit(s), and select Model.
2. Select the following settings:
a. Material to CAP Hard Model Material
b. Manufacturer to your site or Custom Automated Prosthetics
c. Manufacturing process to CAP Milled Model Manufacturing
d. CAD Settings to CAP Milled Hard Model-* and either the Quad or Full options.
3. Select the option to have a removable die, or an unsectioned model.
4. Continue with 3Shape’s guided workflow to create models.
5. At the model building articulation step, you can select or change your articulator setup. CAP’s milling strategy is designed to only support Simple Quadrant or Full Quadrant for the articulator type.
6. The finished Model articulation should look similar to this.
7. After the Model Build has completed, find the case in the 3Shape list, Right Click, and select Advanced > Generate CAM Output.
8. Right click the order again Select Explore CAM to find your files or use the keyboard shortcut “Shift + F4.” If you cannot find the files, they should be in your 3Shape Manufacturing directory in the material folder “CAP Hard Milled Model” and the order number. You are now ready to mill the model with Sum3D with the STL’s generated in that folder.
1. Start a new job using ProCut tools and selecting CAP Model Material to start.
2. Select the model you just built from the manufacturing directory CAP Milled Model Material. Be sure to select Model as the type object. Set the Offset to 4.0. Select NO for Bounding Box Optimizer. Now select Open to bring the job into Sum3D. If your job has an antagonist, repeat this step to bring in the antagonist model.
3. Now, we will add the die objects. Find the die in the same CAP Milled Model Material directory in Manufacturing Directory. This time, select Die as the type object. Set the offset to 5.0 to give a little extra clearance for undercutting. Select NO for Bounding Box Optimizer. Now select Open to bring the job into Sum3D. The image below shows an example of a die being selected.
4. After bringing in the Models, we will see the option to enable undercut milling when selecting the strategy. Place a check in this box if you wish to utilize undercuts with the 1mm tool allow more detailed anatomical models. This will add more time to calculation and milling but will give you greater detail.
5. If the Model is sectioned with a die, you must manually draw our Prep Lines using this button around the top of the insertion hole. Leave the default width of .2. If the model is unsectioned, and there is no die, we do not need to draw Prep Lines. This step is required to tell the software where to mill the die cavity. Repeat for each die cavity.
6. We must now use the Special Area function to define the area where to refine milling for the adjacent contacts next to the die. Draw lines around the die interface and about halfway through the adjacent units. We want extra detail of the contacts to to be milled more accurately fit for the final restoration. Repeat for each area you need refinement
7. All previous and remaining steps such as spruing and object placement in the puck can be done as normal.
