Tough, 3D-Printed Ceramics Could Help Build Hypersonic Planes

Strong, flawless ceramics in various shapes, including spirals and honeycombs, can now can be created using 3D printing, researchers say. One potential strategy for making ceramics that have complex shapes is 3D printing. A 3D printer usually works by depositing layers of material, just as ordinary printers lay down ink, except 3D printers can also lay down flat layers on top of each other to build 3D objects.
