Abstract

Method and device for producing a 3D object by means of a generative 3D-method, for example, selective laser sintering (SLS) and selective laser melting (SLM). An infrared sensor can be cross-flown by a tempered fluid in order to prevent the infrared sensor, which is provided in the process chamber of the device, from being impaired by monomer deposits, oligomers or solid material particles during the construction thereof.
