  • Patent number: 10245786
    Abstract: 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.

  • Patent number: 10183445
    Abstract: A three-dimensional object printer generates image data of an object being formed in the printer with a plurality of light sources and a plurality of optical sensor arrays. A controller receives the image data and identifies measurements of the object and of the features of the object. The controller compares the measurements to expected measurements and adds material or removes material from the object in response to the identified measurements being outside a predetermined range about the expected measurements.
