Accompanying drawing explanation
Fig. 1 is the schematic diagram of the 4th kind of technique of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The mixing stereoforming method of a kind of multicomponent material, it is characterised in that step is as follows:
Step one: preparing matrix (1) and one group of multicomponent material group containing bonding agent, material can be powder body, and its granularity is more than 0.1mm, it is also possible to be sheet material, and its thickness is less than 5mm.Bonding agent can be hot melt adhesive, it is also possible to be water soluble adhesive, and water can also regard special bonding agent as.Here adopt binding agent in order that improve the bonding force of storeroom so that molded body becomes for ease of the preform of machining.Bonding agent can also as lubricant (such as PUR bonding agent), when it is melted time, it can play lubrication, this is conducive to deformation molding, bonding agent can not also be used, such as, when adopting the methods such as plating, Vacuum Deposition (including magnetron sputtering, evaporation etc.) to prepare laminated body, but first must electroplate with multicomponent material, Vacuum Deposition (including magnetron sputtering, evaporation etc.) etc. prepares positive plate or target for use
