A system () and method for monitoring a recoating mechanism (A,B) in an additive manufacturing environment is provided. Various embodiments involve the use of a control computer (-) to receive data based on a thermal image of a recoating mechanism (A,B) from an imaging device () configured to capture thermal image. The control computer (-) further determines a value of a property of the thermal image, wherein the property is related to an amount of powder in the recoating mechanism. The control computer (-) further determines at least one of if the value indicates an error related to the amount of powder in the recoating mechanism (A,B), and an action to take with respect to the recoating mechanism (A,B) that is based on the value.

System and method for monitoring and recoating in an additive manufacturing environment

A method and system for archiving 3D geometry information for a plurality of subjects, and on a particular part of the body (which may also be the whole body) is described. The method and system allow an organizing and an analyzing step, resulting in scalable characteristic components for the particular part of the body, and an approximation of the geometry of that particular part of the body for a specific subject by a combination of a subset of those characteristic components with corresponding scale factors, which are then stored. The method comprises the steps of: *organizing for each of said plurality of subjects the 3D geometry information according to a predetermined standard, thus obtaining organized 3D geometry information; analyzing the organized 3D geometry information of said plurality of subjects, resulting in averaged 3D geometry information of said particular part of the body; and&#x2014;scalable characteristic components of said particular part of the body; such that for each of said plurality of subjects said organized 3D geometry information can be approximated by a combination of said scalable characteristic components relative to said averaged 3D geometry information; comparing, for at least one out of said plurality of subjects, said organized 3D geometry information with said averaged 3D geometry information and determining a subset of said scalable characteristic components and corresponding scale factors, for approximating to a given accuracy said organized 3D geometry information relative to said averaged 3D geometry information by a combination of said scalable characteristic components out of said subset, each characteristic component scaled with its corresponding scale factor; storing, for at least one specific subject out of said plurality of subjects, said approximated organized 3D geometry information by storing&#x2014;said averaged 3D geometry information; &#x2014;said subset of said scalable characteristic components and said corresponding scale factors for said specific subject.

Method and system for archiving subject-specific, three-dimensional information about the geometry of part of the body

Systems and methods for designing and generating a device using accuracy maps and stability analysis are disclosed herein. In some aspects, the systems and methods described relate to an apparatus for designing a device. The apparatus includes a processor configured to generate a three-dimensional model of a physical object and determine whether the three-dimensional model satisfies an accuracy threshold based on an accuracy map. The processor is further configured generate a simulated representation of the device, determine whether the simulated representation of the device satisfies a stability threshold, simulate a fit of the device on the three-dimensional model if the simulated representation of the device satisfies the stability threshold, and determine whether the simulated fit of the device on the three-dimensional model is within a tolerance threshold. The processor is further configured to generate an approved design of the device if the simulated fit is within the tolerance threshold.
