With the rise of additive manufacturing (AM), more and more engineers are exploring lattice structures for their product designs. That’s because AM doesn’t constrain you to solid parts like traditional milling or mold methods.
Imagine replacing a steel bracket with an intricate web that provides ample strength, without the weight.
To help things along, CAD systems can now automate the generation of lattice structures in additive manufacturing. Today, you’re free to add patterns of beams, trusses, diamond-shaped cells, or almost any shape at all to your design—in any configuration—knowing that your 3D printer can produce these shapes.
If that sounds liberating, it is. Perhaps in ways that aren’t apparent at first.
