Beschreibung
Zusammenfassung:	A three-dimensional object printing system improves the collection of waste materials during object printing. The printing system includes an ejector head configured to eject material, a platform configured to move in a process direction to a position opposite the ejector head to enable the ejector head to eject material onto the platform, and first and second planarizers configured to remove a first portion and a second portion, respectively, of the material ejected onto the platform. The printing system further includes a first housing defining a first chamber in which at least one of the first planarizer and the second planarizer is positioned, and a first vacuum source connected to the first housing, the first vacuum source being configured to produce a first vacuum in the first chamber to pull material removed by the at least one of the first planarizer and the second planarizer from the first chamber.
