The Duke was shown two Renishaw additive manufacturing (metal 3D printing) machines recently supplied by the company to the University's School of Engineering and discussed the increasing applications for the technology. Commenting on discussions with the royal visitor, Renishaw's additive manufacturing products division director and general manager Simon Scott said: "He asked many thoughtful questions regarding the technology, particularly concerning its use in applications with tighter regulatory environments such as the aerospace and medical industries. His Royal Highness also expressed concern at the slow pace of uptake of the technology by industry, identifying that a lack of training and technology transfer might be to blame for this situation." There are two Renishaw additive manufacturing machines installed in the School of Engineering, with these part of on-going research collaboration between the University of Liverpool and Renishaw. His Royal Highness also spoke to a number of PhD students based at the University during his visit to the additive manufacturing laboratories, including Ian Ashton, a Renishaw-sponsored research student who is investigating the process control of additive manufacturing machines. Commented Ashton: "It was a pleasure to meet Prince Andrew and it was great to see such high levels of knowledge and interest in UK Science and Technology expressed by a member of the Royal Family."
