NextDent Model

NextDent Model is characterized by its high-precision dental model prints.

Part Quality and Accuracy Tips

In order to achieve good accuracy on Model Oker materials it is important to follow the part setup instructions below for orientation and supports. Some other key tips are as follows:

  1. 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.

  2. Allow parts to dry completely before post cure.
  3. Verify proper cleaning method. Insure cleaning solvents are not saturated and parts are allowed to dry before post cure.
  4. Follow and apply accuracy wizard procedure for each printer to get highest accuracy parts.

Orientation - Arches

Most Model Oker parts are intended to print flat or the bottom surface being parallel to the XY-plane grid on 3DSprint™. The exception is when the model has large cross sectional areas on a full plate part.

For arches, use Orient functions to orient part such that the bottom surface is parallel to the XY-plane grid.

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

For models with a full palate and/or very large cross sectional areas. Angle the model as to reduce the number of surfaces parallel to the XY plane.

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.

Add Supports – Full Arches

Add supports to the part using the Create Supports function under the Smart Supports icon. Look at the supports and determine how they may need to be modified. The supports should only be on the bottom surface of the part.

NOTE: supports should be removed from all numbers or lettering using the Modify tab tools under Smart Support.

Add Supports – Tooth Inserts

Add supports to the part using the Create Supports function under the Smart Supports icon. Look at the supports and determine how they may need to be modified. The supports should only be on the bottom surface of the part. Tooth inserts should not have any supports on the fitting surface.
