One of the benefits of additive manufacturing is that it lets you manufacture complex shapes that would otherwise prove difficult or impossible to produce with traditional processes. Imagine sending this model to be injection molded:
But with additive manufacturing, lattice structures like these are easy to produce. And that’s good news for engineers and designers who want to create strong parts with a fraction of the weight of a solid piece. A lattice with thick walls and small cell sizes can save weight, but still withstand large forces. For other parts, a more “airy” lattice structure can offer just the right support without adding much weight.
In short, lattice structures in the era of additive manufacturing offer powerful new design options for product developers.
That’s why, in Creo 4.0, we introduced support for lattices. Now you can design, optimize, and validate these intricate structures, all from within your 3D CAD software.
Here’s what you need to know to get started building lattice features:
The first type of lattice you’ll want to use in Creo 4.0 is a 2.5D lattice. To create a 2.5D lattice, follow these steps:
Selecting a closed volume.
An octagonal 2.5D lattice.
The second cell type you can see in Creo 4.0 is the 3D lattice.
Like the 2.5D lattice, you can select triangular, square, hexagonal, or octagonal types. However, the 3D lattice structure is based on beams. To create a 3D lattice, follow these steps:
A 3D lattice made of beams.
