SYSTEM FOR ADJUSTING PLATFORM HEIGHT DURING THREE-DIMENSIONAL PRINTING OF AN OBJECT

A three-dimensional object printer uses a mechanical system to adjust a vertical height of a platform that supports a substrate for formation of a three-dimensional object in the printer. The mechanical system includes a Geneva mechanism operated by a rack and pinion arrangement to drive differentia...

Zusammenfassung:	A three-dimensional object printer uses a mechanical system to adjust a vertical height of a platform that supports a substrate for formation of a three-dimensional object in the printer. The mechanical system includes a Geneva mechanism operated by a rack and pinion arrangement to drive differential screws and adjust a vertical distance between the platform and a printhead in the printer.
