Patent number: 11014307Abstract: A method for determining and optimizing manufacturing of an object by additive manufacturing. One or more computers access a three-dimensional digital model of the object and automatically generate a selected number of versions of supports for manufacture of the object. An image of the generated supports is displayed along with the object for visual perception by a user. The user visually observes the displayed versions of supports and object and uses the images to evaluate whether manufacturing the object by additive manufacturing is viable and whether the additive manufacturing supports are optimized. When viable, the object may be built by additive manufacturing using the optimized additive manufacturing supports to support the object.Type: GrantFiled: May 17, 2019Date of Patent: May 25, 2021Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Gregory Colvin, Michael Dillard, Samir Nayak, Robert De Mers, Melissa Bush, Johnathon Wright

Patent number: 10987842Abstract: The invention describes a method of determining and visualizing process parameter values of an injection moulding process, which method comprises the steps of determining geometric data of the injection mould (1F) and/or of a form part (1, 1?, 1?) to be manufactured in the injection mould (1F), carrying out an injection moulding process using the injection mould (1F) and recording measurement values as a function of the injection time and/or an actuator position (s), determining, as process parameter values on the basis of the measurement values and geometry data of the injection mould (1F), a flow front position inside the injection mould (1F) or the form part (1?, 1?) as a function of the injection time and/or an actuator position. The invention further describes a corresponding process parameter value determining apparatus (20) and an injection mould arrangement (10) with such a process parameter value determining arrangement (20).Type: GrantFiled: March 29, 2016Date of Patent: April 27, 2021Assignee: BTMT GmbHInventors: Holger Mensler, Josef Maertl

Patent number: 10974460Abstract: Tracking of measured depth with intervening depositing of one or more layers provides a way of improving the accuracy of surface reconstruction. For example, knowledge of the desired or expected thickness of each layer, in combination with the scan data is combined to yield higher accuracy than is available from scan data of a single scan alone. One application of such an accurate surface reconstruction is in a feedback arrangement in which the desired thickness of one or more subsequent layers to be deposited after scanning is determined from the estimate of the surface depth and a model of the object that is being fabricated, and by increasing accuracy of the surface depth estimate, the precision of the fabrication of the object may be increased.Type: GrantFiled: January 8, 2020Date of Patent: April 13, 2021Assignee: Inkbit, LLCInventors: Desai Chen, Wojciech Matusik

Patent number: 10946551Abstract: In-line inspection and control system to in-situ monitor an extrudate during extrusion. A light beam illuminates a line on the outside circumference of the extrudate skin recording the curvature. A master profile of the illuminated defect-free skin is recorded and compared to successive monitoring of the illuminated skin. Differences from the comparison indicate skin and/or shape defects. A real-time feedback to automatically adjust process control hardware reduces or eliminates the skin and shape defects based on the monitoring and comparison.Type: GrantFiled: November 20, 2015Date of Patent: March 16, 2021Assignee: Corning IncorporatedInventors: Joseph Henry Citriniti, Conor James Walsh
