Continuous improvement in manufacturing process of the aero and marine engines components has been a challenge due to the complexity in design to meet demanding product performance. The focus on R&D is paramount to maintain its competitive edge both on cost and product quality.
About the Speaker:
Kin Teo joined the Rolls-Royce in 2010 from the Advanced Manufacturing Research Centre (AMRC) with Boeing based in Sheffield, United Kingdom. He started off as a research engineer and progressed to the post of a project manager serving the centre for ten years. His main R&D focus on the Aerospace Supply Chain (eg. Rolls Royce plc, The Boeing Company, General Electric, BAe System and Messier Dowty) and assist them to be competitive in the world market with respect to various manufacturing process improvement.
During his career in the Rolls-Royce, he started off as the team leader leading the Mechanised & Advanced finishing Team for the Business. From the last quarter of 2012, he was promoted to lead the Manufacturing Technology - Singapore & Asia consisting of 5 sub-teams with the focus on Surface Modification, Additive Layer Manufacturing and Digital Manufacturing technologies. The main aim of this department is to ensure technology transfer of the development project onto the production floor so as to achieve cost reduction and quality improvement of the power generation components. He was awarded the winner for E&T Engineering Excellence for Creativity 2014 by the Rolls-Royce plc.
In 1998, Kin Teo graduated from the University of Sheffield with Bachelor of Engineering in mechanical enigeering with First Class Honours. Following in 1999, Kin Teo graduated with Master of Science (Research) in Materials, Structures and Systems Engineering.

Director, SUTD Digital DManD and NAMIC@SUTD
Singapore University of Technology and Design
This talk will describe advances in digital manufacturing research at the Digital Manufacturing and Design Centre (DManD) at SUTD, where our mission is to create frontiers in design and manufacturing enabled by the digital thread that integrates the product development and manufacturing value chain. DManD brings together multiple disciplines in computational and industrial engineering, material sciences, technology-intensive design and architecture to create knowledge and technologies for new product innovation. In this talk, I will describe our research to develop computational simulation and design capabilities to enable designers to exploit new design windows enabled by digital manufacturing technologies to create new generations of previously unobtainable products. I will also describe our efforts to create innovative manufacturing technologies based on the digital fusion of sensing, hybrid fabrication processes, as well as new advances in multimaterial and multifunctional 3D and 4D printing.
About the Speaker:
Dr Lim Keng Hui is the Director of the SUTD Digital Manufacturing & Design Centre (DManD), and the Director of the National Additive Manufacturing Innovation Cluster (NAMIC@SUTD). Before joining SUTD, he was the Deputy Executive Director of the A*STAR National Metrology Centre (NMC), and the Director of the A*STAR Engineering Cluster where he managed large scale strategic research initiatives; he had started and managed research programs in Future of Manufacturing (robotics, additive manufacturing, manufacturing-IT, remanufacturing, marine & offshore engineering) that involve public-private partnerships, as well as programs in Urban Systems and Medical Technologies. Before A*STAR, Dr Lim was the CTO of 2 Med-Tech startups in medical robotics and imaging in the US and Singapore; Head of Product Development at an industrial automation company; and research scientist at the Singapore National University Hospital and the Massachusetts General Hospital in Boston. He has consulted for companies, and served on national-level committees in advanced manufacturing, innovation-based productivity, robotics and urban solutions, as well as Standards committees in biomedical and additive manufacturing. Dr Lim was a recipient of the Innovator’s Award from the Prime Minister’s Office for his work on Med-Tech. He received his degrees from Imperial College, MIT and NUS.
One of the main bottlenecks for insertion of additive manufacturing in industrial production lines is the sensitivity of the process, namely, the fact that small changes in process parameters can greatly affect the final part quality. Physics-based computer simulations can address this issue. The role of process parameters in influencing phase transitions, microstructure evolution, and residual stress will be shown.
Modelling and simulations of moving rigid bodies and deformable boundaries are essential in many engineering applications including oil & gas, micro-fluidics and biomedical engineering. Traditional mesh moving techniques for this class of problems encounter issues of mesh quality degeneration and mesh validity. Immersed boundary approach has been a prominent alternative for large motion and deformation problems. We present a moving-least-square immersed boundary method for solving viscous incompressible flow involving deformable and rigid boundaries on a uniform Cartesian grid. The method handles the fluid motion, the deformable interface motion and the interaction with the immersed rigid boundaries simultaneously in order to account for the complex interaction between the fluid and the immersed boundaries. The method finds its application particularly useful in biological fluid dynamics, micro-fluidic devices design or in any other application areas with large boundary deformations and moving boundaries.

Utilising robots for industrial automation incurs significant overhead in terms of manpower and time required for programming and testing. This talk will introduce our technology for in-situ programming that allows users to program industrial robots through speech and gesture interaction. The goal is to enable current factory workers to program robots with minimal training and overhead. Our technology is able to parse and quantify the input of the user and automatically construct executable code, a job currently done by trained roboticists. Furthermore, we developed a modular middleware that guarantees safe execution. These features make our technology well suited to increase productivity, production quality, and safety for high-mix low-volume production, maintenance and repair tasks.
