The invention relates to a
high frequency induction heating assisted cold spraying deposition
metal 3D printing method and device. The
high frequency induction heating assisted cold spraying deposition
metal 3D printing method is characterized by comprising the steps of preparation, pretreatment, cold spraying deposition printing and aftertreatment. The
high frequency induction heating assisted cold spraying deposition
metal 3D printing device is characterized by comprising a case, a printing tray bottom plate, a printing tray installation base, a printing tray, a printing spray head, a horizontal plane movement
assembly, a Z-direction movement
assembly, a high frequency heating component installation plate, a
magnetic flux concentration device, an
induction coil, an insulation material, atemperature sensor, a
gas heating device, a first pressure reducing valve, a first pneumatic
ball valve, a second pressure reducing valve, a second pneumatic
ball valve, a
gas supply device, a metalpowder
storage tank, a
powder feeder, a heating sleeve and a
metal powder collection device. A sealing door is arranged on an opening of the case. The high frequency induction heating assisted cold spraying deposition metal 3D printing method and device have the advantages of remarkably improving the
metal powder cold spraying deposition forming ability, being low in equipment manufacturing and maintenance cost, being applicable to various metal materials and the like.
