Beschreibung
Zusammenfassung:	A universal object holding mechanism for holding three-dimensional objects for printing thereon uses an array of suction cups mounted at the ends of retractable tubes. The array is pressed into an object which in turn is pressed against a datum surface that represents a print head. Vacuum is applied through the tubes to the suction cups which grip the object. The suction cup walls are hollow and filed with particulates that cause the cup to become rigid when the vacuum is applied. This contributes to keeping the object from moving due to flex in the suction cup when it is being moved past the print head.
