"A team from HRL Laboratories in Malibu, California, has developed what they call a pre-ceramic resin, which they can 3D print much like regular polymers into complex shapes. The process, known as stereolithography, fuses a powder of silicon carbide ceramics using UV light. Once the basic shape is printed, it can be heat-treated at 1,800°F to turn the pre-ceramic resin into a regular ceramic object. In fact, this is the first time silicon carbide ceramics have ever been 3D printed.
With fewer limitations on the kinds of materials that can be used, the resulting objects have superior qualities to normal 3D-printed ceramics. With fewer flaws than their counterparts, they resists cracking for much longer, and they can also withstand far higher temperatures, shrugging off 2,500⁰F with relative ease."
