Appliance Design Guidelines

Explore essential design principles for creating dental appliances.

We recommend using SprintRay Cloud Design or AI Studio for all your design needs. If you’d prefer to use your own design software, certain settings must be adjusted to get good results.

The settings in this guide help ensure your 3D files meet the ideal conditions for printing, but they do not guarantee fitment. Check the workflow guide for your appliance type for the best overall results.
