The cold printing techniques of 3D using low-viscosity, high solid loading powder slurry as printing when " ink ", pass through printing
Machine shower nozzle by powder slurry with thread jet deposition to print platform, while triggering material with modes such as chemistry initiation, thermal initiations
The polymerisation of organic monomer in slurry, forms tridimensional network and fixes powder in-stiu coating, powder slurry is solidified rapidly,
The successively printing of metal or ceramic part base substrate is realized, base substrate obtains metal or ceramic part through drying, degreasing and sintering.Its into
Chemical reagent volatilization pollution environment, is limited by drying, degreasing and sintering process in shape complex process, forming process, it is difficult to real
The increasing material manufacturing of the existing fine and close part of large volume, the surface accuracy and dimensional accuracy of part are poor after shaping.
In summary, existing silk material deposition increasing material manufacturing device, moulding material species is limited, can only in forming process
Realize that same material shapes, it is impossible to realize the increasing material manufacturing of multiple material FGM；Due to thermal stress and exemplar
The dimensional accuracy of part is poor after aftertreatment technology, shaping；By rear after silk material adhesive solidification shapes or shaped in forming process
Handling process causes solid phase particles to fuse, and the comprehensive mechanical property of part is poor after shaping.
