Researchers create 3D binder jetted geopolymers competitive with structural concrete

A group of international researchers has produced binder jet 3D printed geopolymer structures competitive with structural concrete for various applications. The primary goal of the research was to 3D print metakaolin, a dehydroxylated form of the clay mineral kaolinite, without the use of cement.  By creating a feedstock made entirely of sand and metakaolin, the […]
