WORLD HUB on Instagram: "The post describes a 2023 Nature Communications breakthrough in 3D printing ceramics without supports, using direct ink writing combined with near-infrared photopolymerization to cure slurry in situ during extrusion, enabling stable overhanging structures like cantilevers. Attached video footage illustrates the process in action, showing a printer depositing a white filament that solidifies instantly under blue light to form a horizontal zigzag span up to several centime

Artificial intelligence | Robotics on Instagram: "This print looks like it’s happening in midair… 🤯 A breakthrough 3D printing method is combining direct ink writing with up-conversion particle-assisted photopolymerization. The result? Ceramic structures printed without any support structures , floating designs that were impossible before. ✨ 👉👉Fallow @aiupdates.hub for more fascinating AI and robotics breakthroughs Credit: Wohlers Associates #3DPrinting #Innovation #Tech
