Patent number: 12077660Abstract: Techniques for debinding additively fabricated parts are described that do not require solvent debinding or catalytic debinding, and that may be performed using only thermal debinding in a furnace. As a result, in at least some cases debinding and sintering may take place sequentially within a single furnace. In some embodiments, the techniques may utilize particular materials as binders that allow for a thermal debinding process that does not negatively affect the parts.Type: GrantFiled: November 13, 2020Date of Patent: September 3, 2024Assignee: Desktop Metal, Inc.Inventors: John Reidy, Christopher Craven, Nihan Tuncer, Animesh Bose, Alexander C.

Publication number: 20150160144Abstract: The condition of internal or hidden material layers or interfaces is monitored and used for control of a process that changes a condition of a material system. The material system has multiple component materials, such as layers or embedded constituents, or can be represented with multiple layers to model spatial distributions in the material properties. The material condition changes as a result of a process performed on the material, such as by cold working, or from functional operation. Sensors placed proximate to the test material surface or embedded between material layers are used to monitor a material property using magnetic, electric, or thermal interrogation fields. The sensor responses are converted into states of the material condition, such as temperature or residual stress, typically with a precomputed database of sensor responses.Type: ApplicationFiled: February 19, 2015Publication date: June 11, 2015Inventors: Neil J.

Patent number: 7812601Abstract: Eddy current sensors and sensor arrays are used for process quality and material condition assessment of conducting materials. In an embodiment, changes in spatially registered high resolution images taken before and after cold work processing reflect the quality of the process, such as intensity and coverage. These images also permit the suppression or removal of local outlier variations. Anisotropy in a material property, such as magnetic permeability or electrical conductivity, can be intentionally introduced and used to assess material condition resulting from an operation, such as a cold work or heat treatment. The anisotropy is determined by sensors that provide directional property measurements. The sensor directionality arises from constructs that use a linear conducting drive segment to impose the magnetic field in a test material. Maintaining the orientation of this drive segment, and associated sense elements, relative to a material edge provides enhanced sensitivity for crack detection at edges.Type: GrantFiled: June 15, 2009Date of Patent: October 12, 2010Assignee: JENTEK Sensors, Inc.Inventors: Neil J.

Patent number: 7451657Abstract: Methods are described for assessing material condition. These methods include the use of multiple source fields for interrogating and loading of a multicomponent test material. Source fields include electric, magnetic, thermal, and acoustic fields. The loading field preferentially changes the material properties of a component of the test material, which allows the properties of the component materials to be separated. Methods are also described for monitoring changes in material state using separate drive and sense electrodes with some of the electrodes positioned on a hidden or even embedded material surface. Statistical characterization of the material condition is performed with sensor arrays that provide multiple responses for the material condition during loading. The responses can be combined into a statistical population that permits tracking with respect to loading history.Type: GrantFiled: January 14, 2005Date of Patent: November 18, 2008Assignee: JENTEK Sensors, Inc.Inventors: Neil J.

Publication number: 20080078778Abstract: This invention is a vending machine and components parts that include a sophisticated positioning system, gripper and trays for improved efficiency in product retrieval and delivery. A unique initialization and calibration system is implemented at start up to determine the positions of shelves and trays of product containers in the machine, and may be implemented at other times if trays or shelves are added or removed, or if tray or shelf positions change. These positions are then used by the positioning and gripping systems to accurately and efficiently retrieve products from the trays.Type: ApplicationFiled: October 30, 2007Publication date: April 3, 2008Inventors: Daniel Carter, Christopher Craven, Walid El-Aouar, Craig Greiner, Larry Hieb, Dean James, Sandra Southard, Rolando Williams

Publication number: 20080061070Abstract: This invention is a vending machine and components parts that include a sophisticated product retrieval and delivery system. Following product selection, the positioning system quickly transports a retrieval device to the front of a tray queue where a product container is retrieved. The positioning system transports the gripper carrying the product container to a delivery port. The product is released and slides down a specially designed chute into a specially designed delivery bucket that is then tilted outward for customer pick up. Sensors associated with the bucket detect the delivery and removal of the product container. Related methods are also disclosed.Type: ApplicationFiled: October 30, 2007Publication date: March 13, 2008Inventors: Daniel Carter, Christopher Craven, Walid El-Aouar, Craig Greiner, Larry Hieb, Dean James, Sandra Southard, Rolando Williams
