Novel energy delivery techniques for laser additive manufacturing from metal powders
Industrial supply of additively manufactured medical components currently falls behind the market demand. This project is geared towards improving the production rate of specific additive parts by adapting the laser delivery to optimise for that particular part by avoiding inherent physical process limitations.

Ultra precision hybrid laser-FIB platform
The integration of ultrafast lasers with metrology systems allows for closed-loop machining to occur. This allows for a sample of unknown properties to be taken inspected, machined, evaluated, and corrected in a single process which increase precision and reduces manufacturing time.

Atmospheric Pressure Plasma Technology For Ultra-Precision Engineering Of Optics For Applications In Aerospace, Defence And Science
New optical technologies increase the demands on the engineering specifications of optical surfaces, with manufacturing specifications of up to 1nm RMS form accuracy and 0.1nm RMS surface finish. To achieve these fabrication requirements novel ultra-precision methods must be developed. The proposed solution is microwave generated activate plasma figuring.

Precision metrology for large freeform non-specular surfaces
There is no standard method for measuring a metre–scale non-specular freeform surface in the ‘ultra-precise’ measurement regime. This project aims to produce a measurement system to enable ultra-precise measurement of these surfaces. The system involves a number of laser trackers to measure the position of a probe as it moves over a surface to be measured.
