Additive manufacturing methods are widely used to make intricately shaped products from polymers and metals. Three-dimensional printed ceramics, however, which could benefit aeronautics and thermal protection systems, are much less common because of challenges imposed by many ceramics’ very high melting points. The limited range of products made this way is formed by using a gluelike material to bind ceramic powders or by fusing them with a laser. But those methods are slow and typically . . .
