Performance Prediction and Process Attribution for Additive Manufacturing


EMSL Project ID
50108

Abstract

The proposed work seeks to develop a modeling-prescribed measurement strategy to generate the data necessary to build a finite element model from which an additively manufactured objects’ performance can be predicted. Data analytics will be used in parallel to identify notable feature characteristics (from production all the way through to end-use) that can be directly correlated as signatures to specific processing conditions. To generate the data set needed for this undertaking, AM standards will be prepared under tightly controlled conditions, with all input variables being recorded throughout the fabrication process. Once these standards are thoroughly validated, conditioning experiments that reflect “in-service” scenarios will be performed. In this way, factors related to aging, such as photo-degradation and hydrolysis, can be incorporated into performance predictions and provenance determination.
