Examining the inherent strains of aluminium alloy 7050-T7451 powder for additive manufacturing processes

Numerical Modeling of the Additive Manufacturing (AM) Processes of Titanium Alloy

Additive Manufacturing of Al Alloys and Aluminium Matrix Composites (AMCs)

Introduction to the Additive Manufacturing Powder Metallurgy Supply Chain

The supply chain for metal powders used in additive manufacturing (AM) is currently experiencing exponential growth and with this growth come new powder suppliers, new powder manufacturing methods and increased competition. The high number of potential supply chain options provides AM service providers with a significant challenge when making decisions on powder procurement. This paper provides...

Residual Stress in Metal Parts Produced by Powder-Bed Additive Manufacturing Processes

In this study, residual stresses from the electron beam additive manufacturing (EBAM) and selective laser melting (SLM) processes, due to repeated thermal cycles, were investigated. Residual stresses play a crucial role in part performance, and thus, it is critical to evaluate the process-induced residual stresses in AM parts. Ti-6Al-4V and Inconel 718 parts produced by EBAM and SLM, respective...

Additive Manufacturing of Casting Tools Using Powder- Binder-Jetting Technology

This chapter presents the use of the additive manufacturing (AM) method powderbinder-jetting (PBJ) for the generation of molds and cores for casting applications. Theoretical information on process steps and the binding of particles is given. For the based chemistry, examples are presented and the transfer from conventional produc‐ tion processes to powder-binder-jetting is explained. For sand ...
