3) keep the open and-shut mode of air valve, move integrally this layer of particle to being positioned at Jiao Chi on, above the grid tightened and close gas check valve, particle is just transferred on grid, reaches the object that grid spreads powder;
4) grid after spreading powder sinks together with particle, carries out applying glue;
5) by bonding for the stratum granulosum after applying glue, be solidificated on workbench or existing stratum granulosum;
6) repeat above absorption successively, paving powder, applying glue and bonding process, to the last one deck, realize the superposition of interlayer, melt removing after extracting Gitterfasern or heating out, form final to be formed.
Described micro-pore suction tray is evenly equipped with the pore dot matrix in some and aperture.
Described pore, according to the shape of individual layer figure, realizes opening and closing separately under the control of air valve.
Described grid is the fiber interweaved in length and breadth tightened.
The raw material adopted is metal, plastics or pottery etc., and epigranular, the circularity of ingredient requirement particle are good.
Compared with prior art, the increasing material manufacture method based on grid paving powder technology provided by the invention, the shaping method in employing face carries out the manufacture of part, can realize direct forming plane, have forming speed fast, support easy reliable advantage.

Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
The present invention includes following steps:
1) according to the shape need of to be formed, build its threedimensional model, and carry out layering sliding-model control according to machine direction;
2) to discrete go out each section figure, again successively discrete is the lattice model of material in each plane, obtains the plane distribution of material;
3) micro-pore suction tray is placed in the top of container for granule, is having the correspondence position of material, opening the air valve of this pore, adsorption particle; Do not needing the position of material, keeping the closed state of corresponding air valve, particle is not adsorbed, and can control the distribution of particle in plane, realizes the dot matrix in kind of particle;
4) keep the open and-shut mode of air valve, move integrally this layer of particle to being positioned at Jiao Chi on, above the grid tightened and close gas check valve, particle is just transferred on grid, reaches the object that grid spreads powder;
5) grid sinks certain degree of depth together with particle, carries out applying glue;
