Thermal process modelling of lattice structures during selective laser melting process

As a type of powder-bed-based Additive Manufacturing (AM), Selective Laser Melting (SLM) is widely used for building metallic lattice structures. However, during SLM process, geometrical imperfections and defects, such as strut over-sizing or under-sizing, typically exist in components due to overheating, which strongly influence their...

Learning from Nature's Failures: Mimicking Hierarchy in Natural Structures to Create Damage-Tolerant Lattice Materials

To create a more sustainable future for aviation, new, lighter-weight structures and materials will need to be engineered. It will also be critical that damage tolerance and safety are not compromised in the process. Lattice materials represents one avenue of exploration; however, two key challenges arise: limited experimental work has been...

Repairability of lattice structure in a circular economy: Mechanical response of 3D printed octet-truss lattice structures under quasi-static loading

Repair and maintenance of products require few resources in a circular economy, minimising the environmental impact of manufacturing and use of products. Although lightweight lattice structures have been widely investigated in various fields owing to their advantages in terms of their mechanical characteristics and the development of additive...
