FIELD: process engineering.
SUBSTANCE: method of producing 3D objects by laser sintering whereat object is produced by IR-radiation curing layer by layer at locations of each layer corresponding to object. In compliance with this method, image of IR radiation emitted by applied powder layer is locally detected to obtain IR radiation image. Note here that IR radiation image is detected by means of infrared chamber. Defects and/or geometrical imperfections in powder layer are revealed by means of IR radiation image.
EFFECT: higher quality of produced object thanks to better quality control in production process.
