New Method for 3D-Printing of SiC
The team from California, has developed a method with a pre-ceramic resin, which they can 3D-print much like regular polymers into complex shapes by a process, known as stereolithography. These polymer structures can be pyrolyzed to a ceramic with uniform shrinkage and virtually no porosity. Silicon oxycarbide microlattice and honeycomb cellular materials fabricated with this approach exhibit higher strength than ceramic foams of similar density. Additive manufacturing of such materials is of interest for propulsion components, thermal protection systems, porous burners, microelectromechanical systems, and electronic device packaging.
