Simple shapes are popular in human designs because they’re easy. Easy to design, especially with CAD, and easy to manufacture in a world where manufacturing means taking a big block or sheet of something, and machining a shape out of it, or pouring metals into a mold.
But manufacturing is starting to undergo a revolutionary change as 3D printing moves toward commercially competitive speeds and costs. And where traditional manufacturing incentivizes the simplest shapes, additive manufacturing is at its fastest and cheapest when you use the least possible material for the job. That’s a really difficult way for a human to design – but fairly easy, as it turns out, for a computer. And super easy for a giant network of computers.
The result: a stronger object, less weight, and less cost.
