A prime example is aircraft engine ducts, where acoustic liners must endure high-pressure airflow loads while absorbing noise. However, conventional structural designs often fall short, requiring bulky soundproofing layers that compromise efficiency. \n\nThis project introduces a groundbreaking approach to lattice metamaterials, using computationally designed architectures to achieve exceptional structural integrity and sound absorption. Their programmability enables precise control over mechanical and acoustic responses through tailored topology. Integrating cross-disciplinary expertise with advanced laser-based additive manufacturing, this work enables the fabrication of intricately engineered structures.\n\nThe outcomes promise substantial benefits to Australia economically, socially, and environmentally. These novel lattice metamaterials can significantly enhance infrastructure by enabling quieter, stronger, and more durable engineering solutions. They also support sustainable manufacturing by optimising material usage and minimising environmental impact. To maximize impact beyond academia, the project will engage industry stakeholders to drive product innovation and expand market reach. These engagements are expected to accelerate technological adoption and strengthen Australian manufacturing, aligning with the Future Made in Australia initiative."}}}
