Saturation (S) is the measured value of how much binder volume is being added to the powder bed in the given geometry of a part, as described in Eq. ( 1). No powder bed is dense, so saturation is the measure of void space in the part that is being filled with a binder. S = Vbinder Vvoid = 100, 000 × Vdrop (1 − D100)×x × y × z.
