Real-Time AM Process Models Applied to Wire Fed Robotic Pulsed-Arc Processed 4340 Steel

This STTR will focus on demonstrating feasible methods to integrate additive manufacturing (AM) structure, processing, and property-geometry modeling methods that will facilitate the qualification and certification of AM-fabricated 4340 steel alloy parts and enable their rapid deployment. During the Phase I feasibility demonstrations the contractor and Research Institute (RI) will define and develop a concept for innovative real-time process models for AM of 4340 robotic pulsed-arc, wire feed materials. They will demonstrate the feasibility to monitor and model the fabrication process and predict the resulting material micro-structures and mechanical properties of the fabricated materials and conduct an initial structural test to confirm properties of the feature shape.
