2nd, shifting axle 22 drives scraper 301 and nozzle 21 shifts to shaped platform 31, and 301 bottom surface of scraper is less than stock chest 32
Interior Copper Powder Surface, so as to push the copper powder for being located at upper strata to shaped platform 31,301 bottom surface of scraper is again flat higher than molding simultaneously
Platform 31, and with the spacing of shaped platform 31 layer thickness is printed for one；
3rd, copper powder is pushed into shaped platform 31 by scraper 301, forms a powdery printable layer（It does not solidify）, nozzle 21 enter into
After type platform 31, according to the print data of control unit, local hydrojet printing is proceeded by, is solidified in powdery printable layer needs
Position jet printing solution, it is still powdered not need to the position of solidification, and nozzle 21 both moved along in shaped platform 31
22 longitudinal direction of axis（Y-direction）It is mobile, and with shifting axle 22 laterally（X to）It is mobile, it is printed so as to fulfill plane, with the fortune of nozzle 21
It is dynamic to be completed up to entire printable layer prints；
4th, shifting axle 22, nozzle 21 again move into initial position, and control unit control shaped platform 31 declines one and beats
Layer height is printed, the bottom plate 321 of stock chest at least rises a printing layer height（Generally slightly larger than the height of a printable layer）；
5th, repeat the above steps 2-4, until printing terminates.
Metal 3D printing device nozzle transfer mechanism described in the present embodiment drives nozzle 21 laterally to move by shifting axle 22
Dynamic, nozzle 21 realizes the plane fortune of nozzle 21 simultaneously under the driving of showerhead electrode 20 along 22 longitudinal movement of shifting axle
Dynamic, total is succinct and compact, can realize quick movement by showerhead electrode 20 and mobile motor 25, shaping efficiency is high；It beats
During print, by high-precision nozzle successively jet inhibitor, a complete three-dimensional part outer profile is preliminarily formed, later by rear
Sequence operation preheating becomes a smooth outer profile in high-melting-point, surface, then melt by reheating, makes to be enclosed in wheel
Metal powders melt in exterior feature, because the smooth final surface for realizing part of outer contour surface is equally smooth, is beaten into an entity
It is high to print precision.
