The researchers at HRL Laboratories (Hughes Research Laboratories) currently owned by General Motors Corporation and Boeing in Malibu, California,  elaborated a special technology: “We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. 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.” HRL focuses on advanced developments in microelectronics, information & systems sciences, materials, sensors, and photonics, from basic research to product delivery.
