Soluble Cores for Fiber Reinforced Composites
http://cimquesttv.wistia.com/medias/kc5jonbtqz?embedType=async&videoFoam=true&videoWidth=640 With FDM, engineers can 3D print sacrificial cores using soluble material. Cores can then be wrapped with a fiber reinforced composite to form high performance parts with advanced geometries and intricate internal features.
