NextDent Model 2.0 is characterized by its high degree of accuracy, making this material suitable for detailed master prosthodontic and orthodontic models where high precision is needed. The models show highly visual details due to color and opacity and has an ideal surface for scan impressions.
The accurate printed models are the perfect base for creating your dental work piece. Available in colors Oker, Peach, White and Grey.
In order to achieve good accuracy on Model 2.0 materials it is important to follow the part setup instructions below for orientation and supports. Some other key tips are as follows:
- For best results use the Resin Mixer to gently stir between prints and after the resin has been sitting overnight.
CAUTION: Do NOT press down on the film when stirring.
- Allow parts to dry completely, a minimum of ten minutes, before post cure.
- Verify proper cleaning method. Insure cleaning solvents are not saturated.
- For high detail printing of models.
- Solid models must be printed at a 5° angle.
- Hollow models can be printed flat or at a 5° angle.
- Ensure the correct Support Style is used based on the orientation (Flat or 5° support style).
- Full prosthodontic models with palate must be hollow and printed at an angle that eliminates cupping.
Orientation - Solid Models
Must be printed at a 5° angle from the XY plane.
|Figure 1. Model tilted 5°.|
Orientation - Hollow Models
Can be printed flat or a 5° angle from the XY plane.
The Manual selection in the Orient function allows the user to select the base of the part. Once chosen, selecting SET BASE will auto orient the part to be flat.

Orientation- Full Palate Models
Full palate models should be oriented in a way that prevents cupping. Depending on the model, an angle between 15° to 30° may be needed to remove the trapped volume and for resin/air clearance.
Rotate the part and then use the Z-Clipping Tool in the View window to see the cross sectional areas of the part. Find the largest cross section and then rotate the part 15-30 degrees to reduce the cross sectional area.

Tooth inserts should not have supports on the fitting surfaces.

Extra care must be taken to use the correct support style depending the orientation of the parts (flat or 5°) to prevent print failures.
|Figure 12. Use correct support style.|
|5° Orientation||Flat Orientation|
|Flat support style - bad||5° support style - optimal||Flat support style - optimal||5° support style - sub-optimal|
Supports - Full Palate Models
- Ensure the correct support style is used (Flat or 5°).
- Extra supports may be required around the palate area to ensure accuracy and print quality.
