Experiments on miniature 3D printed lightweight lattice structures shed light on structural weaknesses

Researchers at LLNL (Lawrence Livermore National Laboratory) have successfully tested theoretical models for predicting the behaviour of miniaturized lattice structures under pressure. 3D printing was used to make small-scale lattices on which various tests were carried out. The results of the tests validated the researchers’ theoretical modelling of the structures’ failure behaviour, which is relevant information for their future applications in engineering and design. You’ll probably be familiar with the lattice structure from trestle bridges, or perhaps its most famous application, the Eiffel Tower in Paris. The lattice allows for low density structures with a high level of specific […]
