The model was made by simulating the Cahn-Hilliard equation, using Paraview to get a level set from the three-dimensional data, printing this figure with support given by a dissolvable filament. So when the print came off the printer, the box was completely filled. Then I put the print in an acid called D-Limonene. The acid dissolves the filament, leaving only the desired shape.
As a side note on the acid experience, D-Limonene is made out of highly concentrated orange rind and is an ingredient in some air fresheners. Even though I left the container with the acid sealed in the garage, for several days the entire house smelled like someone had over freshened the air. Even after several soaks in water, the print still has a pleasant orangey tang.
