Design Principles

"Tribological performance of additively manufactured components is intrinsically linked to their surface topography and microstructure, necessitating deliberate control through process selection and post-treatment."

For designers and engineers utilizing additive manufacturing, understanding and controlling surface finish is paramount for ensuring the durability and performance of components, especially in applications involving motion and contact. This knowledge allows for targeted post-processing techniques to optimize wear resistance and extend product lifespan.
