Just beautiful. We are experimenting with ceramic gelcasting lately[1]. It involves the use of a gel-based slurry, typically made by mixing ceramic powders (such as zirconia, alumina, or silicon carbide) with a liquid binder and a gelling agent in a 3D printed mold. It is a versatile manufacturing method used to create complex ceramic parts. Upon reading the article it occurred to me that the same method could be used to make those kinds of "dune core" pieces, with sand instead of ceramic powders. There must be a sand-binder-gelling solution formulation that can handle the task.
