Additive manufacturing is now mature and is becoming a mainstream production technique for various industries. It is important that engineering services organizations equip themselves to provide a new range of services in this sector. This paper presents an engineering process framework for evaluating and adopting additive manufacturing. It describes tools developed to improve engineering servi...

Metal fabrications experience complex physical metallurgical processes during additive manufacturing, leading to residual stress and coarse microstructure with directional growth. It significantly affects the comprehensive performance of fabrications, which limits application manufacturing. Ultrasonic impact treatment (UIT), as a strengthening means assist can effectively improve state refine p...

Purpose This research aims to exploit the potential of Ultrasonic Additive Manufacturing (UAM) in the embedding of printed electrical materials directly into the interlaminar region of parts during manufacture in order to realise novel multifunctional Metal Matix Composite’s (MMC’s). Design/methodology/approach To ensure the proper electrical insulation between the printed conductor and metal m...

Ultrasonic additive manufacturing (UAM) is a rapid prototyping technology that features a metal joining process through ultrasonic welding. The bonding mechanisms and mechanics of UAM have been investigated for decades. Meanwhile, the plastic deformations of metals were extensively studied by many researchers for their significant roles in bond formation. However, most of these research efforts...

Directed-energy deposition is a 3D printing method that uses focused energy source, such as plasma arc, laser, or electron beam to melt material simultaneously deposited by nozzle. As with other additive manufacturing processes, this technology used add existing components, for repairs, build new parts. Direct-energy techniques have gained much attention from the industry build/repair in-servic...

Additive manufacturing (AM) has been considered for distributed manufacturing. However, the consideration usually concerned AM in general, not specific processes. This paper will look at properties of different processes from perspective process and materials, post-processing, requirements devices spaces, raw materials. The findings show that powder bed fusion binder jetting pose challenges mat...
