Using RE to Enable and Support AM (3D Printing)
Digital definition is becoming more common and the need for validation of the produced product is even more critical. As Additive Manufacturing (3D Printing) is becoming a tool in everyone's tool box, we can now utilize Reverse Engineering to obtain the data for producing products previously without data sets. Printing directly from electronic data means we can create any object. Being able to produce anything does not mean it is accurate. Reverse engineering and scanning with the use of lasers is now enabling a lot of data to be collected very quickly. When millions of points can be captured in minutes we can now utilize this data to ensure product conformance to quality specifications. This data can be used to identify process deviations and lead to means of control.

Effect of Thermal Gradients on Micro-Structure & Mechanical Properties During AM of Ti-6AI-4V Using Directed Energy Disposition
In Additive Manufacturing (AM), especially Directed Energy Deposition (DED) processes, the complex and non-uniform thermal gradients during multiple heating and cooling cycles directly affect the microstructural characteristics, and subsequently mechanical properties of the deposited component. Therefore, prediction of microstructure evolution during the build process is critical. This presentation will share developed process microstructure models on Ti-6Al-4V, and challenges in deploying these models to DED processes, especially Wire + Arc Additive Manufacturing (WAAM), Laser Metal Deposition with wire (LMD-w) and Electron Beam Additive Manufacturing (EBAM), in order to correlate microstructural development with different weld processing conditions. This is one of the bottle necks why wire base DED processes are not completely automated. Case studies, like simple geometry components, will be presented. This study will benefit aerospace companies who deposit Ti-6Al-4V components, and this will help them understand different ways to maintain their attractive business case.
