Patent number: 10241309Abstract: A lighting unit (10) configured to illuminate a surface (32) having a proximal portion (34) and a distal portion (36) in relation to the lighting unit. The lighting unit includes a light source (12) configured to emit a light beam (28), and an optic (40) positioned between the light source and the surface to modify the emitted light beam to have a largely uniform vertical illumination distribution along the surface. The input surface (39) of the optic faces the light source and has a convex lens portion (41) that directs a portion of the emitted light beam at the distal portion of the surface, and a concave lens portion (43) that directs a portion of the emitted light beam at the proximal portion of the surface.Type: GrantFiled: April 6, 2016Date of Patent: March 26, 2019Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Peter Isaac Goldstein, Eric Anthony Roth, Oliver Dross, Benjamin Daniel Sweet-Block

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

Patent number: 6989115Abstract: A three-dimensional printer includes multiple printheads for printing binder and/or colorant onto a bed of build material in a build chamber. The printheads can be mounted on a gantry that is designed for reciprocal displacement across a build chamber along a slow axis. The printheads, in turn, can reciprocally move across the gantry on a fast axis to enable displacement of the printheads along both the fast and slow axes so that the printheads can deposit binder liquid and/or colorant across the surface of a bed of build material in the build chamber.Type: GrantFiled: May 8, 2001Date of Patent: January 24, 2006Assignee: Z CorporationInventors: David B. Russell, Walter Henry Zengerle, III, Peter Charles Conway, James F. Bredt, Benjamin Daniel Sweet-Block, Robert Anthony Phillips
