The gas flow and wire feed rate databases contain wire feed rate needed for the shape layer of a variety of different thickness and Base gas flow；The base gas flow is 5ml/min~500ml/min, and the wire feed rate of the wire feeder is got over Greatly, the base gas flow is bigger；

The plasma generator of any of step 401 and step 4022 the plasma beam processing unit (plant) with it is described Wire feeder is synchronized in moving process in the horizontal plane, and the speed detection unit (18) is to the wire feed rate of the wire feeder Carry out detection in real time and by institute's detection information synchronous driving to wire feed rate controller (20), the wire feed rate controller (20) According to the wire feed rate of the predetermined wire feeder and speed detection unit (18) institute's detection information is combined to wire feed drive Motivation structure (14) is controlled, and the wire feed rate for making the wire feeder is identical with predetermined wire feed rate；

Before any of step 401 plasma beam processing unit (plant) is printed, the gas flow controller (12) According to detection of gas flow rate unit (11) institute's detection information and by controlling flow control valve (29) by the gas stream of air supply pipe (5) Amount is adjusted to the base gas flow；It is described in any of step 401 plasma beam processing unit (plant) print procedure The gas flow of air supply pipe (5) is the base gas flow；

Any of step 4022 plasma beam processing unit (plant) is printed and is synchronized in temperature control process, the gas stream Amount controller (12) is according to detection of gas flow rate unit (11) institute's detection information and combines distance detection unit (8) institute detecting distance Information, and by the way that flow control valve (29) is controlled to be increased and decreased adjustment to the gas flow of air supply pipe (5)；Also, the nozzle Outlet and the distance between horizontal stamp pad (4) it is bigger, the gas flow of the air supply pipe (5) is bigger.
