Traditional 3D printing has always relied on stacking flat layers—a technique that’s about as structurally sound as a pile of pancakes. However, researchers at the University of Manchester have thrown a brilliant curveball into the mix. By training an ABB robot arm via a neural network to print along non-planar, curved paths, they’ve unlocked a way to create significantly tougher components. The upshot? A massive boost in durability, the total elimination of wasteful support material, and one less reason to rely on breakfast-based metaphors for serious structural engineering.
