GM Standards: From Additive Material Development to Production Use

The use of additively manufactured components on production vehicles begins with material development and characterization. ‘Material Cards’ enable General Motors (GM) to virtually simulate and validate components, ensuring that part and system-level requirements are met. The accuracy of these simulations is heavily dependent on the material properties used as inputs. Standard static/ambient condition datasheets often fall short in accounting for rate and environmental dependencies critical in automotive applications. GM has established rigorous standards for testing, characterization, and performance at both the material and part levels. This presentation will cover GM’s defined requirements and processes for material characterization and testing, part performance standards, and the steps to collaborate with GM in characterizing additive materials and validating components for production applications.

By the end of this presentation, participants will have a clear understanding of GM’s material characterization process and its significance in the development of automotive components, the difference between material and part level standards, and how to collaborate on material and part development for automotive applications.
