APPARATUS FOR SPRAY DEPOSITION

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 t...

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. Theapparatus 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. 本发明涉及通过喷涂沉积生产3D物体的装置。该装置具有粉末输送管线A，用于将夹带在载气中的喷涂材料流输送至喷嘴(第一流)。该装置还具有工艺管线B，其用于将气流输送至喷嘴(第二流)。该装置还具有喷涂喷嘴8。该装置使得对所述第一流的压力和温度参数进行实时控制，但不对所述第二流的这些参数进行实时控制。所述两个流合并以将喷涂材料从喷嘴8推进至基体来形成3D物体。
