Zusammenfassung:	This invention relates to apparatus for producing a three-dimensional object by spray deposition. The apparatus has a powder conveyance line A line arranged to channel 5 a flow of spray material entrained in a carrier gas to a nozzle (a first flow). The apparatus also has a process line B arranged to channel a flow of gas to the nozzle (a second flow). The apparatus also has a spray nozzle 8. The apparatus is such that pressure and temperature parameters of the first flow are controlled in real time, but for the second flow these parameters are not controlled in real time. The two flows 10 merge to cause spray material to be propelled from the nozzle 8 to a substrate to create a three-dimensional object. La présente invention concerne un appareil de production d'un objet tridimensionnel par dépôt par pulvérisation. L'appareil comprend une ligne de transport de poudre (A) agencée pour transporter un flux de matériau de pulvérisation entraîné dans un gaz vecteur vers une buse (un premier flux). L'appareil comprend également une ligne de traitement (B) agencée pour transporter un flux de gaz vers la buse (un second flux). L'appareil comporte également une buse de pulvérisation (8). L'appareil est conçu de telle sorte que des paramètres de pression et de température du premier flux sont commandés en temps réel, mais de telle sorte que, pour le second flux, ces paramètres ne sont pas commandés en temps réel. Les deux flux fusionnent pour amener un matériau de pulvérisation à être propulsé depuis la buse (8) vers un substrat pour créer un objet tridimensionnel.
