Above-mentioned metal 3D printing system operation principle：
1st, first, shifting axle 22, shower nozzle 21 reset to initial position, and shaped platform 31 rises to highest point, regulation stock chest bottom
Plate 321, make the raw metal in stock chest 32（The present embodiment is copper powder）Higher than shaped platform 31；
2nd, shifting axle 22 drives scraper 341 and shower nozzle 21 shifts to shaped platform 31, and the bottom surface of scraper 341 is less than in stock chest 32
Copper Powder Surface, so as to push the copper powder positioned at upper strata to shaped platform 31, the bottom surface of scraper 341 is higher than shaped platform again simultaneously
31, and be a printable layer thickness with the spacing of shaped platform 31；
3rd, copper powder is pushed into shaped platform 31 by scraper 341, forms a powdery printable layer（Do not solidify）, it is flat that shower nozzle 21 enters shaping
After platform 31, according to the print data of control unit 4, local hydrojet printing is proceeded by, in the position that powdery printable layer needs to solidify
Put jet printing solution, it is not necessary to which the position of solidification is still powdered, and shower nozzle 21 both moves along axle in shaped platform 31
22 longitudinal directions（Y-direction）It is mobile, and with shifting axle 22 laterally（X to）It is mobile, so as to realize that plane prints, with the motion of shower nozzle 21
Until the printing of whole printable layer is completed；
4th, shifting axle 22, shower nozzle 21 again move into initial position, and shaped platform 31 declines a printing layer height, stock chest
Bottom plate 321 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 system described in the present embodiment, quick transfer and lifting, terminal with compact integral structure are realized by motor
And it is compact, relative to the print system of traditional SLM device, volume significantly reduces, and production cost and later maintenance into
This is also reduced.During printing, high-precision shower nozzle 21 successively jet inhibitor, a complete three-dimensional part outline is preliminarily formed,
A smooth outline in high-melting-point, surface is become by subsequent operations preheating afterwards, then melted by reheating,
Make to be enclosed in the copper powder in profile and be melt into an entity, because of the smooth final same light in surface for making part of outer contour surface
It is sliding, realize the high printing of precision；Because need to only print the outline of part during printing, so as to substantially increase the efficiency of shaping.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
