  • Publication number: 20220291661
    Abstract: Methods of simulating additively manufacturing an object may include generating a simulated additively manufactured object based at least in part on a plurality of approximate consolidation domains that respectively correspond to a plurality of consolidation tracks determined from one or more digital representations of an additively manufactured object, and determining a predictive inference with respect to one or more material properties of the object to be additively manufactured based at least in part on the simulated additively manufactured object. Methods may include generating, for an object to be additively manufactured, a CAD file and/or a build file based at least in part on a simulated additively manufactured object and/or based at least in part on one or more predictive inferences with respect to one or more material properties of the object to be additively manufactured.

  • Patent number: 11154934
    Abstract: Build material application device (5) for an apparatus (1) for additively manufacturing at least one three-dimensional object (2) by means of successive layerwise selective irradiation and consolidation of layers of build material (3) which can be consolidated by means of at least one energy beam (4), the build material application device (5) comprising: —at least one build material application element (8) configured to apply an amount of build material (3) in a build plane (E) of a respective apparatus (1) for additively manufacturing at least one three-dimensional object (2); —at least one spatter removal element (9) configured to remove spatters (10) present in a layer of build material (3) of a respective apparatus (1) for additively manufacturing a three-dimensional object (2), particularly to remove spatters (10) originating from a selective irradiation of the respective layer of build material (3).

  • Publication number: 20200086558
    Abstract: Method for operating an apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (5), wherein at least one region in a build plane (6) is irradiated in the additive manufacturing process, wherein an interrupted state of the additive manufacturing process is determined and a defined amount of energy is deposited in at least one previously irradiated region (7, 8) of the build plane (6) in an interrupted state of the additive manufacturing process.

  • Publication number: 20200031054
    Abstract: Apparatus (1) for additively manufacturing three-dimensional objects (2, 2?) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy source, which apparatus (1) comprises a stream generating device (6) that is adapted to generate a gas stream (7, 7?) inside a process chamber (5) of the apparatus (1), wherein the stream generating device (6) is adapted to control at least one parameter relating to a composition of the gas stream (7, 7?).
