Step 4, the most successively print: to multiple described workpiece to be formed synchronize carry out by down to On successively print；
Wherein, when workpiece to be formed any one described is the most successively printed, all in accordance with step In rapid three obtain this workpiece to be formed multiple described layering cross section printing path from the bottom to top by Layer prints, it is thus achieved that the finished workpart stacked from the bottom to top by multiple shape layers；Multiple described The shape layer being positioned at bottommost in shape layer is bottom；In the quantity of described shape layer and step one, this is treated The quantity in the described layering cross section of shaping workpiece is identical, the installation position of multiple described shape layers respectively with Installation position one_to_one corresponding and its thickness in multiple described layering cross sections are the most identical, the layer of described shape layer Distance between thick and adjacent two described layering cross sections is identical, and in step 3, this workpiece to be formed is many The printing path in individual described layering cross section is respectively the printing path of multiple described shape layer；
When synchronizing the most successively to print to multiple described workpiece to be formed, process is as follows:
Step 401, bottom print: print the bottom of multiple described workpiece to be formed respectively, And the bottom Method of printing of multiple described workpiece to be formed is the most identical；Treat multiple described workpiece to be formed After bottom has all printed, enter step 402；
Wherein, when the bottom of workpiece to be formed any one described is printed, all comprise the following steps:
Step 4011, walking displacement: by the traveling controller electric walking to multiple described print platforms Walk mechanism to be respectively controlled, the described print platform printed for this workpiece to be formed is moved to described etc. The underface of ion beam current system of processing；Now, it is positioned at immediately below described plasma beam system of processing Described print platform be platform to be controlled；
Step 4012, print: described position adjustment controller is treated into according to acquired this in step 3 The printing path of the current institute printing shaping layer of type workpiece, the stamp pad position to described platform to be controlled Adjusting apparatus is controlled and drives horizontal stamp pad to move in the horizontal plane；Described level prints In platform moving process, interior band is melted the plasma beam of liquid stream even by described plasma beam system of processing Continue and be sprayed onto on horizontal stamp pad；After melted liquid stream all solidifies, complete beating of current institute's printing shaping layer Print process；
Step 402, last layer print: the upper shape layer difference to multiple described workpiece to be formed Print, and the Method of printing of a upper shape layer of multiple described workpiece to be formed is the most identical；
Wherein, when the upper shape layer of workpiece to be formed any one described is printed, all include Following steps:
Step 4021, walking displacement and horizontal stamp pad move down: first pass through traveling controller to multiple institutes The electric walking mechanism stating print platform is respectively controlled, described in printing for this workpiece to be formed Print platform moves to the underface of described plasma beam system of processing；Now, it is positioned at described plasma Described print platform immediately below line system of processing is platform to be controlled；Afterwards, described position adjustment Controller, by controlling the stamp pad position regulator of described platform to be controlled, drives horizontal stamp pad In the vertical direction once moves down and moves down the thickness phase of height and described shape layer With；
Step 4022, print and synchronize temperature control: described position adjustment controller is obtained according in step 3 The printing path of the current institute printing shaping layer of this workpiece to be formed taken, to described platform to be controlled Stamp pad position regulator is controlled and drives horizontal stamp pad to move in the horizontal plane；Institute State in horizontal stamp pad moving process, described plasma beam system of processing interior band is melted liquid stream etc. Ion beam current is sprayed onto on the upper surface of the most printed described shape layer of the next one continuously；Wait to melt After liquid stream all solidifies, complete the print procedure of current institute printing shaping layer；
