Though the forms are drawn from indigenous sources, the production of 3-D printed tiles and other components is anything but. The two also invented a software application for a 3-D printer that extrudes wet clay, pushing it through a nozzle like a gigantic toothpaste tube. A series of clay vessels called “Bad Ombrés ” was produced by this extrusion method: the name alludes both to President Trump’s comment about Mexicans and a term for the gradual blending of one color into another. The clay is built up layer by layer, producing striated patterns and surfaces resembling knitting, complete with knots and loops. As they document in “Printing Architecture: Innovative Recipes for 3D Printing,” published last year, mud is dear to their hearts.
