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.
