摘要： An irradiation assembly for additively manufacturing three-dimensional objects may include an irradiation device and a magnetic mounting device configured to displaceably support the irradiation device. The irradiation device may include one or more illumination elements respectively configured to emit an energy beam. The magnetic mounting device may include a magnetic slider element coupled to the irradiation device and a magnetic stator element couplable to a housing structure of an additive manufacturing machine. The magnetic stator element may include a displacement track configured to guide the magnetic slider element along a movement path above at least a portion of a construction plane of the additive manufacturing machine while the one or more illumination elements respectively emit the energy beam to selectively irradiate build material at specified regions of the construction plane.

摘要： An additive manufacturing system configured to additively build an article can include an energy applicator, a build platform, and a powder nozzle configured to eject powder toward the build platform to be acted on by the energy applicator. The system can include a control module configured to control the energy applicator to create an amorphous structure forming at least a portion of the article.

摘要： A laser operating machine for laser sintering (100) is described for making three-dimensional objects starting from a digital 3D model by sintering the layers with the use of a laser source and an optical system, mechanical means for depositing a powder bed on a work surface, and a mechanical system to remove the fumes and/or pollutants deriving from the selective powder melting process as close as possible to the melted layer or layer, before they are dispersed inside the work chamber, and to introduce in the same chamber the process gases necessary for the processing of powder bed fusion in a localized manner, close to the layers or layers subject to the selective melting process.
