Analysing the effects of 3D printing defects and surface roughness on the properties of acoustic materials
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)The principal aim of the research reported in this thesis was to investigate the influence of additive manufacturing on the acoustic performance of 3D printed periodic materials. First, a benchmark material design was ... -
Application of the Theory of Critical Distances to As-Built Selective Laser Melted Ti-6Al-4V
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Metal additive manufacturing (AM) techniques such as selective laser melting (SLM) have become an increasingly present feature of new and novel manufacturing methods in recent years. This is owed to further technological ... -
The Impact of Additive Manufacturing on the Acoustic Performance of Novel Porous Materials
(2022)Commonly used conventional acoustic porous materials suffer from a limited operational frequency range and great dependency of the sample thickness on their performance. For this reason, acoustic metamaterials have caught ... -
Modelling techniques to inform the design of sub-wavelength periodic acoustic structures
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2022)Minimising the environmental impact of aircraft noise and ensuring the sustainability of air travel in the future is crucial for the development of the industry. The ad- vancement in additive manufacturing paves the way ... -
Optimisation and 3D Printing of Paediatric Stents
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)Aortic coarctation is a congenital heart defect that occurs 3 per 10,000 live births with a life expectancy of 35 years if left untreated. Stenting is a common treatment method, but devices are not specifically designed ... -
Surface Free Energy Dominates the Biological Interactions of Postprocessed Additively Manufactured Ti-6Al-4V
(2022)Additive manufacturing (AM) has emerged as a disruptive technique within healthcare because of its ability to provide personalized devices; however, printed metal parts still present surface and microstructural defects, ...
