NextDent Gingiva Mask is a flexible material that can be used in combination with the model material. This makes it possible to print parts of the model that need a certain flexibility, such as Gingiva Masks on implant models.
In order to achieve good accuracy with Gingiva mask it is important to follow the part setup instructions below for orientation and supports. Some other key tips are as follows:
- If printing tall parts (not typical of the Gingiva Mask parts), be sure to place them >10mm from each other on the build area.
- If parts are tacky (stick to gloves) after following the cleaning procedure, rinse with fresh IPA, before drying and checking for tackiness again.
- Verify proper cleaning method. Insure cleaning solvents are not saturated and parts are allowed to dry before post cure.
Gingiva mask parts normally have a flat bottom surface. The flat bottom should be oriented away from the XY-plane of the grid in 3DSprint™. Best orientation is on its side with supports on lingual or palatial side.
Figure 1. The gingiva mask part is oriented with the bottom surface parallel to XY-plane.
Add Supports –
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. Supports on the gingiva mask part should not occur on the flat bottom surface or in the holes.
In addition an overhang may need to have a support added.
When using 3DSprint™ Modify tab to view the location of the supports, note the node may appear to be going thru the part. If unsure, zoom into the node and see if it is properly placed.
Figure 2. The gingiva mask part has a support added to the front to improve the overhang.
