While significant progress has been made in the last few years, the reliability of Additively
Manufactured (AM) parts is often less than desirable as they suffer from manufacturing …

In recent years, the significant residual stress in the wire-arc additively manufactured
components has been continuously one of the most concerning issues for the further …

Abstract Metal Big Area Additive Manufacturing (mBAAM) offers the potential to fabricate
large scale tools at high deposition rates (15 lb/h+). 410 martensitic steel is a potential …

With the recent rise in the demand for additive manufacturing (AM), the need for reliable
simulation tools to support experimental efforts grows steadily. Computational welding …

Purpose The purpose of this paper is to develop, apply and validate a mesh-free graph
theory–based approach for rapid thermal modeling of the directed energy deposition (DED) …

This work investigated the linear thermal expansion properties of a multi-material specimen
fabricated with Invar M93 and A36 steel. A sequence of tests was performed to investigate …

New and more complex casting technologies are growing, and foundries are using
innovative methods to reduce cost and energy consumption and improve their product …

We present a system for 3D printing large-scale objects using natural biocomposite
materials, which comprises a precision extruder mounted on an industrial six-axis robot. This …

Due to rapid, localized heating and cooling, distortions accumulate in additive manufactured
laser metal deposition (LMD) components, leading to a loss of dimensional accuracy or …

Laser Metal Deposition with wire (LMD-w) is one of the novel Direct Energy Deposition
(DED) processes that is gaining attention in aerospace industry due to the potential cost and …
