3D printed ceramics isn’t a new thing at the market of materials for printing. Ceramics is light, strong and have extraordinary thermal properties that make this material high demanded by 3d printing fans.
The most common for 3D printed ceramics techniques for nowadays is putting layers of material on top of each other and as a result, receive the material with a low melting points. However, it’s necessary for very simple forms of the object. Now, there was developed a new way to 3d print this material and make it more effectively and increase the withstand temperature to 2,500°F.
HRL Laboratories are using a more accurate stereolithography technique called stereolithography, fusing a powder of silicon carbide ceramics using UV light, to create highly detailed, strong and heat-resistant ceramic 3D prints.
“We have a pre-ceramic resin that you can print like a polymer, then you fire the polymer and it converts to a ceramic,” said Tobias Schaedler, senior scientist at HRL. “There is some shrinkage involved, but it's very uniform so you can predict it.”
