Patent number: 10830578Abstract: A method and an apparatus are directed to characterizing a continuously moving 3D object via interferometry-based scanning. The method includes repeatedly forming several depth characterizations of the 3D object along respective scan lines of a plurality of scan lines on the surface of the 3D object. During this scanning, the 3D object is undergoing its continuous motion. The method further includes combining the determined depth characterization along the scan lines of the plurality of scan lines to form a depth map representing at least a depth of a portion associated with a location on the surface of the 3D object in the third direction on a grid of locations arranged in the first and second directions. Forming the depth characterizations includes scanning a frequency-dispersed pulsed optical signal in a first direction across the continuously moving 3D object, said 3D object moving in a second direction substantially orthogonal to the first direction.Type: GrantFiled: October 17, 2019Date of Patent: November 10, 2020Assignee: Inkbit, LLCInventors: Aaron Weber, Kiril Vidimce, Walter H. Zengerle, III, Desai Chen, Wojciech Matusik

Publication number: 20100151136Abstract: A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.Type: ApplicationFiled: February 23, 2010Publication date: June 17, 2010Applicant: Z CorporationInventors: Thomas Davidson, Robert A. Philips, Andres T. Hernandes, David B. Russell, Kevin Roche, Walter H. Zengerle, III, Andrew Berlin, Joshua P. Kinsley, Benjamin Daniel Sweet-Block, Darul Kisai
