However\, due to intrinsic materials characteristics\, e.g.\, solidifi cation cracking\, not many aluminium alloys have satisfactory LPBF process ability. Therefore\, it is in urgent need to design and develop more suita ble aluminium alloys and their composites for LPBF manufacturing. Meanwhil e\, once new aluminium alloys are designed\, it is also of great importanc e to optimise the LPBF process to achieve high quality components without any apparent processing defects such as cracks or porosity. Moreover\, how to achieve the desired mechanical properties in these aluminium alloys vi a manipulating the LPBF optimised parameters is another interesting and pr ofound topic. In this presentation\, a novel in-situ alloy design process was first introduced to develop nanoparticle decorated aluminium alloys fo r LPBF and the resultant microstructure along with mechanical properties w ere investigated. Following this\, a machine-learning assisted LPBF proces s optimisation process for aluminium alloys is described in detail to prov ide new insights into the microstructure control and properties manipulati on of LPBF fabricated aluminium alloys.\n \n \nBio\nDr Xiaopeng Li is cu rrently a tenured Senior Lecturer and Australian Research Council DECRA Fe llow in the School Mechanical and Manufacturing Engineering at The Univers ity of New South Wales (UNSW Sydney)\, leading a research group working on additive manufacturing and advanced materials research. He is also a memb er of UNSW Artificial Intelligence Institute and a member of Australian Ce ntre for Space Engineering Research. He received his PhD degree in Materia ls Engineering from The University of Queensland\, Australia in 2013\, whe re his PhD thesis won the Best Thesis Award by Australian Research Council Centre of Excellence for Design in Light Metals in 2013. After his PhD\, he joined The University of Western Australia as an Assistant Professor\, working on additive manufacturing of metallic glasses\, light alloys and t heir composites till 2016. Following this\, he joined one of the world-fam ous additive manufacturing groups led by Prof Jean-Pierre Kruth at KU Leuv en\, Belgium as a Research Fellow till 2017. Dr Li has published 1 book ch apter and 71 journal papers (5 ESI Highly Cited Papers and 2 cited ≥400 times and another 8 cited ≥100 times) with a total citation number of 34 00 (Google Scholar). As of 2022\, Dr Li has an H-index of 29 and FWCI of 3 .54. In the past ten years\, Dr Li has contributed to many fundamental and industrial-related research projects as a Lead Chief Investigator/Project Coordinator with a total funding around AUD 10 million in Australia and E urope and has given more than 40 invited presentations at international co nferences and universities. Since 2020\, Dr Li has been listed as World’ s Top 2% Scientists in Materials & Applied Physics & Enabling Strategic Te chnologies (single year in 2019 and career in 2020) in the database of the most-cited scientists developed at Stanford University. He is currently t he editorial board member for a few prestigious international journals inc luding Scientific Reports\, Metallurgical and Materials Transactions A\, e tc. and also a member of many international professional/academic communit ies including TMS. In addition\, he also serves as a co-chair or a member of organising committee for a number of international conferences includin g the 1st and 3rd Asia-Pacific International Conferences on Additive Manuf acturing (APICAM)\, the “3D-print of Ceramics” Symposia for the 11th I nternational Conference on High-Performance Ceramics. Dr Li is also a regu larly invited reviewer for many competitive research grants including Euro pean Research Council and Australian Research Council. His specific resear ch interests include: development of various materials for additive manufa cturing\; design\, simulation and machine learning for additive manufactur ing\; processing-microstructure-property relationship in additive manufact uring\; hybrid additive manufacturing\; and advanced materials and structu res.
