Abstract
An apparatus for powder-based additive manufacturing of an object is provided. The apparatus includes a powder delivery mechanism, a powder recoating mechanism, an irradiation beam directing mechanism and a temperature control mechanism that at least measures a real-time temperature of at least one growing part of a built object. The apparatus includes a build unit, a positioning mechanism, and a rotating mechanism. The build unit attaches to the positioning mechanism providing the build unit with independent movements in at least two dimensions. The build unit also attaches to the rotating mechanism and rotates around and above a build platform during production. A method of manufacturing the object using the apparatus includes repetitive cycles of depositing powder onto a build platform, irradiating at least one selected portion of the powder to form at least one fused layer, and measuring a real-time temperature of at least one selected portion of the at least one fused layer.
