EngD student, 2016 intake

University: The University of Nottingham

Sponsoring company: Renishaw

Background: Undergraduate Masters in Mechanical Engineering at University of Edinburgh, graduating in June 2016.

Additive manufacturing (AM) is the process of creating a component by building layer upon layer, to create a net-shape or near net-shape part. Most people are familiar with the concept of polymer 3D printing, however selective laser melting (SLM) is used to create metallic components, typically with highly complex geometries, which would be difficult or impossible to create with traditional subtractive methods. This ability to create complex structures gives SLM potential for use in high value industries such as aerospace, tooling and medical devices. However uptake of this technology has been held back by inspection limitations of such complex build geometries post-production and a lack of robust in-situ inspection methodology.

This project will exploit the expertise at the University of Nottingham in Laser Ultrasonic inspection techniques along with Renishaw’s experience in both metrology and AM to develop a robust on-line inspection technique. Specific objectives of this project are to progress inspection approaches which produce quantifiable (fitting with the Quantitative NDT research theme), and easily interpreted results. Providing a reliable NDE technique for SLM components will help to improve industry confidence in the technology and facilitate further uptake of technology in the commercial sector. Attention will be paid to both the time and cost impact of on-line inspection on the overall build process.
