FIELD: technological processes.
SUBSTANCE: method for making three-dimensional objects consists of the following stages: depositing of layer of the construction material, subject to strengthening due to effect of electromagnetic or corpuscular radiation on substrate or layer strengthened earlier (a), strengthening of the layer of the construction material due to effect of electromagnetic or corpuscular radiation on the corresponding cross section of the object in spots in the layer (b), repetition of the previous stages (a) and (b) until the three dimensional object is completed. The temperature of the construction material is measured by a non contact method using a device for measuring temperature in the measuring zone, which is partially the zone of the layer. The position of the measuring zone is determined or measured using apparatus for adjusting position independently from change in the position of the zone, on which electromagnetic or corpuscular radiation on stage (b) has effect. The device for making a three dimensional object through strengthening of layers of the construction material on the corresponding cross section of the object due to effect of electromagnetic or corpuscular radiation, has a device for measuring temperature for non contact measurement of the temperature of construction material in the measurement zone, which is partially the zone of the layer of construction material, and also has apparatus for adjusting the position for changing the position of the measurement zone for the device of measuring temperature independently from the position of the zone, on which the energy of the radiation has an effect. Using this device, an unexposed surface can be actively selected for measuring the temperature of each layer, and due to change of the position of the measuring zone, temperature distribution in the layer can be measured as well.
EFFECT: cheap and simple to use device; simple and cheap method for making three dimensional object through strengthening of layers of construction material on corresponding cross section of object due to effect of electromagnetic or corpuscular radiation.
