The invention relates to a method and to a 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 said infrared sensor (6), which is provided in the process chamber (1) of the device, from being impaired by monomer deposits, oligomers or solid material particles during the construction thereof.

L'invention concerne un procédé et un dispositif de fabrication d'un article tridimensionnel par l'intermédiaire d'un procédé 3D génératif tel que par ex. un procédé de frittage laser sélectif (SLS) ou un procédé de fusion laser sélectif (SLM). Pour éviter qu'un capteur à infrarouge (6) présent dans la chambre de traitement du dispositif (1) ne subisse l'influence de précipitations de monomères, oligomères ou de particules solides lors du processus de montage, celui-ci peut être entouré par un courant de fluide tempéré.
