Multi-axis 3D printing with curved layers! 🖨️ Researchers from... the The University of Manchester introduced a neural network-based computational pipeline as a representation-agnostic slicer for multi-axis 3D printing. Traditional 3D printing works like stacking pancakes, flat layers on top of each other. 🥞 This often requires temporary support structures that get thrown away after printing, wastes material, and creates weaker parts. Multi-axis 3D printing can print along curved paths that follow the object's natural shape. This eliminates support structures and makes stronger parts. But figuring out these curved paths is mathematically complex, you need to avoid collisions, respect what the printer can physically do, and optimize for strength. The neural network solves this automatically. It learns to create a "field" around the object, then extracts curved printing paths from this field. Because the entire process is differentiable (translation for non-math specialists, meaning you can optimize it end-to-end), the AI can directly optimize for manufacturing goals like "no support structures needed" and "make it as strong as possible."

Exploration of complex structures

This print appears to be happening in midair… a... new method of 3D printing: It combines direct ink writing with up-conversion particles-assisted photopolymerization. With this method of printing ceramics, the need for support structures is eliminated. Near-infrared light cures the ceramic material as it leaves the nozzle, allowing structures to be printed horizontally without collapsing. The researchers demonstrated unsupported spans exceeding 85 mm. Paper: Credit: Wohlers Associates —— Weekly robotics and AI insights. Subscribe free:show more
