Design Principles

"Material efficiency through stress-informed design."

This approach allows designers to create highly efficient, single-piece components that are lighter and potentially stronger than traditionally manufactured multi-part assemblies. It directly addresses the automotive industry's need for weight reduction to improve fuel efficiency and performance, while also streamlining production through additive manufacturing.

What This Means for Your Design

Using computer tools to figure out where a part needs to be strong and where it doesn't, we can remove unnecessary material to make it much lighter without making it weaker.
