The Core Objectives

Developing Computational Methods

One of the primary goals is to develop computational methods for efficient qualification of additively manufactured parts. This means creating mathematical models and simulations that can predict the behavior and performance of parts under various conditions. These methods are indispensable for ensuring that AM parts meet stringent quality and safety standards.

Process-Variable Optimization

The project aims to exploit and control the variability inherent in AM processes. Variations in microstructures and porosity have historically been considered challenges, but this project seeks to turn them into opportunities. By treating process variability as a feature and not a bug, researchers can develop more robust and versatile AM processes.

Process-Part Co-Design

This innovative approach involves the simultaneous optimization of process control variables, part geometry, and material properties. In essence, the process and the part are designed together, considering real-time variability control. This method can lead to improved part performance and easier AM process control.
