Development of 3D metal printing capability for challenging environments
Lead Research Organisation:
CRANFIELD UNIVERSITY
Department Name: Sch of Aerospace, Transport & Manufact
Abstract
The work is focused but not limited to remote environments, such as underwater, nuclear and low gravity. This applied research will be based on fundamental investigation and understanding of forces affecting melting characteristics and solidification of weld bead in 3D printing. The main focus will be put on laser-based sources. Understanding the fundamental principles of pressure, gravity and other forces on laser-material interaction and formation of the melt pool is vital to develop robust process. Different research methods, including experimental trials with various monitoring equipment and numerical modelling will be used to understand phenomena governing the process. The project will require cross-field collaboration and development of sophisticated experimental set-ups to gain insight into the process physics.

Description | We have discovered that gravity plays a role in manufacturing a part. There is a threshold at which gravity starts to influence the processes. We have studied different deposition processes in different orientations and carried out simulation modelling to understand the effect of gravity. It was found that when a large amount of liquid metal is deposited in a zero-gravity, it keeps its shape and size. While in 1g, the shape cannot be obtained due to surface tension taking over the process. The shape of the liquid metal in 0g is rounder and higher. In 1g its flatter and wider. |
Exploitation Route | It can be used to investigate further AM manufacturing processes in 0g or in other gravitational conditions. |
