While “additive manufacturing” is preferred by most engineers, the term “3D printing” is far more common particularly in the popular media. Calcium Fluoride (CaF2) Calcium fluoride (CaF2 or fluorite) is grown by vacuum Stockbarger technique in diameters of up to about 250mm. Hence, the application of APF gel retains more fluoride.
