During metal casting, cores are emplaced in the mold. Cores with high moisture content give rise to porosity in the cast part therefore impairing quality. The project goal was to create a visual humidity indicator to determine moisture content of a 3D printed core. We accomplished this by successfully incorporating phenolphthalein into sand based powder in the printing process. The success of our project will optimize digital manufacturing and metal casting by ensuring high quality cast products and improved productivity.
