You might be aware that PTC CAD extensions provide you with functionality that supports 3D printing. These extensions allow you to carry out advanced tasks such as the following:
- Configure lattice structures in your part models.
- Automatically position and optimize orientation of parts on the print tray.
- Nest parts in your print tray assemblies.
- Save and modify your print tray assemblies.
