Additive manufacturing enables us to explore designs which include internal cavities or intricate structures otherwise impossible or difficult to manufacture. Creating "Lattices" in your design can enable you to remove some material while maintaining the structural rigidity and integrity.

In a conventional approach, a designer could add holes or simple cavities for weight reduction.
Now with Lattice Designing available for academic users, you can design intricate structures to remove some and keep some material in a cool 3D pattern called a "Lattice".

Lattice Design will be available for Academic use with FD02 update, Coming on 13th may!
