Rocco Lupoi
Assistant Professor, Mechanical & Manuf. Eng
Biography
Dr. Rocco Lupoi was appointed Assistant Professor within the Mechanical & Manufacturing Engineering Department, Trinity College Dublin, in July 2012; the year after he was awarded of a prestigious Marie Curie Fellowship. He is a mechanical engineer by background, obtaining an MEng degree from Politecnico di Torino (Italy) in July 2004 over a "vecchio-ordinamento" course of studies. In the same year he was awarded of a grant for a PhD programme in the University of Bath (UK), with thesis title "Effect of shape, size and material on energy dissipation in Equal Channel Angular Extrusion". In this challenging work, he investigated the concepts and working mechanisms of a novel technology known as UREAD capable of dissipating energy in engineering systems against the occurrence of unwanted events (such as earthquakes, crashes and collisions) and with the potential of being 100% re-usable. After being awarded of a PhD degree in October 2008, he was appointed Research Associate in the Institute of Manufacturing (IfM) - Cambridge University (UK) to explore innovative melting-free material additive processes. He is a recognized expert of Cold Spray and other deposition methods, and he is one of the inventors of a new LASER-based coating technology known as "SprayLaze". He is a major contributor in the field, with high-rank publications, patents submitted and an article in a Nature Publishing Group - NPG journal. Dr. Lupoi in Trinity is exploring new manufacturing processes to include Cold Spray and Selective Laser Melting; he is the lead PI of a large research project in this topic funded by the European Space Agency. Dr. Lupoi is a Funded Investigator of AMBER and I-Form which are SFI research centres. Lectured modules within the School of Engineering are 1MEMS1 - Introduction to Manufacturing (1st year); 5MEMS2 - Advanced Manufacturing (4th year and Master level); 5MEMS1 - Advanced Manufacturing II (Master level).

- Title
- Implementing Additive and Cold Spray Techniques for the smart manufacturing of valve componenTs (IMPACT)
- Summary
- Currently, the Fourth Industrial Revolution, or Industry 4.0, is under way. It is marked by emerging technology breakthroughs in a number of fields, including robotics, artificial intelligence, nanotechnology, quantum computing, biotechnology, 3D printing and autonomous vehicles. As we find ourselves firmly in the 4th industrial revolution, there are at least three major impacts for manufacturing industry emerging: additive manufacturing, energy and resource efficiency, and data. Additive Manufacturing (AM) is in essence the industrialisation of 3D Printing, and we see additively manufactured metal parts becoming more mainstream, for example in aeroengines as GT nozzles, in the field of medical such as hips and knee prosthesis and many other applications. The successful implementation of this project will result in two major impacts: 1. Allowing the company partner to manufacture customized high-end valves with complex structure by SLM at low cost and short production circle. 2. The modification of the valves structure can be achieved without damaging the original body via CS, which significantly reduce the cost by designing and manufacturing a new valve.

- Duplex solid-state surface engineering for novel thermal control coating systems on spacecraft
- Summary
- This research proposal is a collaborative research project between TCD, ENBIO and Cranfield University to develop new surfaces for use in thermal control of surfaces on spacecraft. Thermal control is important on a spacecraft as the on-board instruments need to stay at a consistent temperature, while the outside of the craft is exposed to extreme Solar radiation. Thermal control relies on radiative heat-transfer mechanisms (control the amount of UV light that is absorbed or reflected), and to emit heat in the long wavelength infra-red. New surfaces are developed to increase the stability and lifetime of thermal control coatings, especially for new, smaller spacecraft such as CubeSats. ENBIO's SolarBlack is a char-bone based thermal control coating, already qualified for use in Space on the ESA's Solar Orbiter mission. The project will focus on the thermal & optical aspects of new coating systems under a simulated space environment. The project novelty is the investigation and combination of a range of techniques: metal matrix composites (MMCs), CoBlast and Cold Spray. This combination will produce a surface with novel material performance compared to basic systems. The coating system will be produced by a combination of MMCs coating (fabricated by Cold Spray at TCD) followed by 'SolarBlack' (deposited by CoBlast at ENBIO) on top. Optimised coating system will be applied to spacecraft grade metals and tested by ENBIO and Cranfield University under simulated service conditions. The processing parameters' effect on the material structure and thermo-optic stability of coating systems in extreme environments will be investigated.

- Supersonic-assisted laser ablation for the deposition of thin coatings at high rates
- Summary
- Pulsed Laser Deposition (PLD) is widely used to make thin films not amenable to conventional methods, such as thermal evaporation and sputtering. Despite critical technical advantages, PLD presents low deposition rates and currently finds limited applications in industry. In this TIDA we will investigate and assess a new thin film deposition technique (called SALA), based upon PLD principles, but with the potential to deliver high deposition rates and within an atmospheric environment. Laser ablation is used to vapourise the coating material, where it is entrained in a supersonic gas flow and carried at high velocity to a substrate for deposition.

- Novel Hybrid Additive Manufacturing for the Fabrication of Functionally Graded Multi- Materials Components
- Summary
- Functionally graded multi-materials (FGMs) components are characterized by spatially variation of materials or microstructures, resulting in multiple properties and functions at different parts. FGMs are able to gain the best of all constituent materials, having wide applications in the modern industry. Additive manufacture of a near-net-shape FGMs component with fine details is always a challenge work because the welding of incompatible materials results in large residual stress, high porosity and cracks at the multi-materials interface, especially in metals. In this research, the work aims to develop a hybrid additive manufacturing technology combining selective laser melting (SLM) and other emerging techniques to fabricate high-quality FGMs components, currently not possible to be manufactured.

- Exploring metal-AM and novel 3D printing techniques for the manufacturing of devises in orthopaedics
- Summary
- The background of this programme is directly linked to metal Additive Manufacturing (AM). Techniques that constitute this field, such as Selective Laser Melting (SLM) and Electron Beam Melting (EBM) have shown great progress in recent years. It is now possible to directly 3D print components with complex features and with minimum post-processing operations before reaching the net shape. For example, the typical SLM process would require no tooling, is fully automated, and can manufacture components with multi-features in one single processing step. Metal AM has therefore attracted the interest of several sectors; however it seems particularly well suited for the biomedical industry. Using conventional manufacturing processes, this would require investment casting, complex machining processes, finishing processes coupled with etching and coatings steps to achieve a final product. Using SLM, these manufacturing steps can be reduced significantly.

- Development of Cold Spray towards the next generation Additive Manufacturing
- Summary
- Cold Spray (CS) is an innovative coating manufacturing process, which allows for the formation of material layers in a solid-state (free of melting) manner. In this method, the feedstock material (in the form of powder) is injected at the inlet of a converging-diverging supersonic nozzle. The nozzle is fed with high pressure gas (nitrogen or helium), which expands through the internal channel and reaches supersonic speed at the exit (above 1000m/s). Particles are dragged by the fast jet, and upon impact against a substrate material they plastically deform and stay bonded. This project aims at developing a unique CS laboratory facility, the first one in Ireland, for CS applications in Space programmes in the form of coatings and and 3D components made out of composites and metals.

- Supersonic Spray Advanced Modelling - SSAM
- Summary
- Current methods for the manufacturing of metallic coatings onto non-metallic surfaces are slow, limited in size and to a small range of feedstock materials. Also, they require time-consuming masking steps or complex etching procedures, have low bond strengths, and are coming under very strong pressure to limit their environmental impact through the elimination of toxic waste products. This project will start investigating a revolutionary powder-based technology which will lead to the device of a mask-free, environmentally friendly and low-cost deposition process tailored to the manufacturing of metallic coatings onto non-metallic components. The deposit formation is completely solid-state (free of melting). This programme, Supersonic Spray Advanced Modelling - SSAM, will generate the required computational tools to study and control the particles acceleration process within the processing nozzle.
