FIELD: process engineering.SUBSTANCE: invention relates to production of 3D body by application of powder plies and fusion of their selected zones corresponding to cross-sections of 3D body. For at least one of plies, at least one powder ply is applied on working zone and fused by feed of power from irradiation gun to selected zone. Note here that beam preset path is set for fusion of selected zone for at least one powder ply. Temperature in at least one powder play in imaginary beam path is calculated as the function of beam specific power along preset beam path. Acton of imaginary beam power specific power along preset beam path subject to calculated temperature and conditions set for fusion of selected zone. Said calculations and adjustments are used to plot actual beam power action working diagram for preset beam path at fusion of selected zone of at least one ply.EFFECT: control over temperature, accelerated construction of 3D body.10 cl, 8 dwg, 1 ex |
